  • JSON Feed Appears to be XHR when it should be JS

    - by Oscar Godson
    I don't get why it'd doing this with the 2nd feed (appearing as a XHR call rather than just JS [looking at it in Firefox/Firebug]). The 2nd feed has the exact same MIME type as Flickr's JSON feed, yet the PortlandOregon.gov one shows as XHR and i get a NULL callback when using $.getJSON and if i use $.ajax with a 'json' or 'jsonp' type i get nothing at all. If i do the Flickr one i get the normal "[object Object]" callback. Whats going on? Please help! This has been such a headache for about a week. And i have authorization to change the feed, but i have to request the change, so if anyone knows for absolute sure let me know that!

  • help with jquery ajax and templates in asp.net mvc

    - by NachoF
    So I have a complex form for an IncomeDeclaration. Its going to display a textfield GrossIncome for each Activity that the IncomeDeclaration is related to... this all gets done on the server and works just fine.... the problem is. The User should also be able to add Activities on the fly.. through javascript... so when the user clicks on Add Activity a Dropdown and a textfield must be appended to the bottom the activities list... heres what Ive got so far <tbody id="activities"> @Html.EditorFor(model => model.income.EconomicActivityIncomeDeclarations) </tbody> </table> <a href="#" id="add_activity">Agregar Otra Actividad</a> </fieldset> <script type="text/javascript"> $("#add_activity").click(function () { $.getJSON('/IncomeDeclarations/GetEconomicActivities', function (data) { var select = new Select(); var data = new Array(); for (var i = 0; i < data.length; i++) { var option = new Option(data[i]["name"], data[i]["i"]) //should do something here } //should call the template and append to #activities }); }); </script> <script id="template" type="text/x-jquery-tmpl"> <tr> <td><select name="income.EconomicActivityIncomeDeclarations[${SomeNumber}].EconomicActivityId"> ${MyOptions} </select></td> <td><input type="text" name="income.EconomicActivityIncomeDeclarations[${SomeNumber}].GrossIncome" /></td>> </tr> </script> } The name attribute for both the select and the text_field is key for this to work... otherwise modelbinding wont work... I would think that if the SomeNumber variable is set to new Date.GetTime() model Binding should work just fine... I actually dont see the need of ajax for this but thats another topic.. I just havent figured out a way to do this without ajax... right now I want to get the template to work and append the form elements to the bottom of the list.

  • load Javascript object from file

    - by megapool020
    Hi there, I asked a question in this thread Stackoverflow, and it works perfect. So tnx to all the users who gave me a reply. But now I have a other question. I would like to have the object in a seperate file, so I only need to update the file in stead of the JS file (otherwise it will be very big). I'm using JQUERY. I now looks like this (with all the info in the JS file). IBANInfo is used to fill a selectbox var IBANInfo = { "ccAL":{ countryCode:"AL", countryName:"Albani&euml;", IBANlength:"28", bankFormCode:"0 8n 0 ", accountNum:"0 16 0 " }, "ccAD":{ countryCode:"AD", countryName:"Andorra", IBANlength:"24", bankFormCode:"0 4n 4n", accountNum:"0 12 0 " }, "ccBE":{ countryCode:"BE", countryName:"Belgi&euml;", IBANlength:"16", bankFormCode:"0 3n 0 ", accountNum:"0 7n 2n" } }; //---- then this function is used to build the selectList function createSelect(){ var selectList = ''; var key; selectList += "<option value=''>Kies een land</option>\n"; for (key in IBANInfo) { if (IBANInfo.hasOwnProperty(key)) { var countryInfo = IBANInfo[key]; selectList += "<option value='"+countryInfo.countryCode+"'>"+countryInfo.countryName+"</option>\n"; } } $('#selectBox').html(selectList); } I thought I could do it like this, but I get the message undefined in my selectbox. var IBANInfo = $.get('include/countryCodes.txt'); // also tried var IBANInfo = $.getJSON('include/countryCodes.txt'); //---- then this function is used to build the selectList function createSelect(){ var selectList = ''; var key; selectList += "<option value=''>Kies een land</option>\n"; for (key in IBANInfo) { if (IBANInfo.hasOwnProperty(key)) { var countryInfo = IBANInfo[key]; selectList += "<option value='"+countryInfo.countryCode+"'>"+countryInfo.countryName+"</option>\n"; } } $('#selectBox').html(selectList); } /* the countryCodes.txt file is like this: { "ccAL":{ countryCode:"AL", countryName:"Albani&euml;", IBANlength:"28", bankFormCode:"0 8n 0 ", accountNum:"0 16 0 " }, "ccAD":{ countryCode:"AD", countryName:"Andorra", IBANlength:"24", bankFormCode:"0 4n 4n", accountNum:"0 12 0 " }, "ccBE":{ countryCode:"BE", countryName:"Belgi&euml;", IBANlength:"16", bankFormCode:"0 3n 0 ", accountNum:"0 7n 2n" } } */ What am I doing wrong. Tnx in advance

  • JSon/Jquery request with a setTimeout always returns a "null" result? (for Twitter Search API)

    - by supermogx
    I make a call to the twitter API. 100 posts are retreived + a properties that tells me what the next page to call is. So I wait 5 sec. and call that next page, but the JSon results in the callback function is always null the second time... I think it's probably a JQuery problem... Here's a complete sample HTML code : <html> <head> <script type="text/javascript" src="./jquery-1.4.2.min.js"></script> <script> function test() { var rqUrl = "http://search.twitter.com/search.json?q=%23apple+OR+%23ipad&rpp=100&callback=?" callTwitterSearchApi(rqUrl); } function callTwitterSearchApi(tiwtterRequestUrl) { debug("request to twitter : " + tiwtterRequestUrl); // *** FIRST CALL WORKS GREAT... *** $.getJSON(tiwtterRequestUrl, callTwitterSearchApi_callback); } function callTwitterSearchApi_callback(jsonPostsResults) { debug("callback"); if (jsonPostsResults == null) { debug("Why is jsonPostsResults null? If I copy paste the request inside a browser, I get something =("); return; } if (jsonPostsResults.error != undefined && jsonPostsResults.error != "") { debug("twitter api error"); } var posts = new Array(); $(jsonPostsResults.results).each(function() { posts.push(this); }); debug("Number of posts : " + posts.length); if (jsonPostsResults.next_page != undefined && jsonPostsResults.next_page.trim() != "") { debug("calling next request in 5 sec..."); // *** WHEN COMMING BACK FROM THAT LINE, JSON RESULTS == NULL?! **** setTimeout("callTwitterSearchApi(\"http://search.twitter.com/search.json" + jsonPostsResults.next_page + "\")", 5000); } } function debug(message) { document.getElementById('debug').innerHTML = message + "\n" + document.getElementById('debug').innerHTML; } </script> </head> <body> <input type="button" onclick="test();" value="test" /><br /> <textarea id="debug" cols="80" rows="20"></textarea> </body> </html> at line 18, at the second callback (back from the setTimeout), the parameter "jsonPostsResults" is always returned as null... I have no idea why. If I copy paste that 2nd request in a browser, it returns 100 results. Anybody had a problem like that with the Ajax JQuery functions when calling it with a setTimeout?

  • highlight query string in more than one field using solr search feature

    - by Romi
    i am using solr indexes for showing my search results. to show serch results i am parsing json data received from solr. i am able to highlight a query string in search result but only in a single field. for this i set hl=true and hl.fl="field1". i did it as $.getJSON("http://192.168.1.9:8983/solr/db/select/?wt=json&&start=0&rows=100&q="+lowerCaseQuery+"&hl=true&hl.fl=description,name&hl.usePhraseHighlighter=true&sort=price asc&json.wrf=?", function(result){ var n=result.response.numFound var highlight = new Array(n); $.each(result.highlighting, function(i, hitem){ var match = hitem.text[0].match(/<em>(.*?)<\/em>/); highlight[i]=match[1]; }); $.each(newresult.response.docs, function(i,item){ var word=highlight[item["UID_PK"]]; var result = item.text[0].replace(new RegExp(word,'g'), '<em>' + word + '</em>'); }); for this json object is as : { "responseHeader": { "status": 0, "QTime": 32 }, "response": { "numFound": 21, "start": 0, "docs": [ { "description": "The matte finish waves on this wedding band contrast with the high polish borders. This sharp and elegant design was finely crafted in Japan.", "UID_PK": "8252", }, { "description": "This elegant ring has an Akoya cultured pearl with a band of bezel-set round diamonds making it perfect for her to wear to work or the night out.", "UID_PK": "8142", }, ] }, "highlighting": { "8252": { "description": [ " and <em>elegant</em> design was finely crafted in Japan." ] }, "8142": { "description": [ "This <em>elegant</em> ring has an Akoya cultured pearl with a band of bezel-set round diamonds making" ] }, } } Now if i want to highlight query string in two fields i did as hl=true hl.fl=descrption, name my json is as: { "responseHeader":{ "status":0, "QTime":16 }, "response":{ "numFound":1904, "start":0, "docs":[ { "description":"", "UID_PK":"7780", "name":[ "Diamond bracelet with Milgrain Bezel1" ] }, { "description":"This pendant is sure to win hearts. Round diamonds form a simple and graceful line.", "UID_PK":"8121", "name":[ "Heartline Diamond Pendant" ] }, "highlighting":{ "7780":{ "name":[ "<em>Diamond</em> bracelet with Milgrain Bezel1" ] }, "8121":{ "description":[ "This pendant is sure to win hearts. Round <em>diamonds</em> form a simple and graceful line." ], "name":[ "Heartline <em>Diamond</em> Pendant" ] } } } Now how should i parse it to get the result. suggest me some general technique, so if i want to highlight query in more fields then i could do so. Thanks

  • jQuery Form plugin - no data from file upload?

    - by pojo
    I've been struggling a bit with the jQuery Form plugin. I want to create a file upload form that posts the data (JSON, from the chosen file) into a REST service exposed by a servlet. The URL for the POST is calculated from what the user chooses in a SELECT dropdown. When the upload is complete, I want to notify the user immediately, AJAX-style. The problem is that the POST header has a Content-Length of 0 and contains no data. I would appreciate any help! <html> <head> <script type="text/javascript" src="js/jquery-1.4.2.min.js">/* ppp */</script> <script type="text/javascript" src="js/jquery.form.js">/* ppp */</script> <script type="text/javascript"> function cb_beforesubmit (arr, $form, options) { // This should override the form's action attribute options.url = "/rest/services/" + $('#selectedaction')[0].value; return true; } function cb_success (rt, st, xhr, wf) { $('#response').html(rt + '<br>' + st + '<br>' + xhr); } $(document).ready(function () { var options = { beforeSubmit: cb_beforesubmit, success: cb_success, dataType: 'json', contentType: 'application/json', method: 'POST', }; $('#myform').ajaxForm(options); $.getJSON('/rest/services', function (data, ts) { for (var property in data) { if (typeof property == 'string') { $('#selectedaction').append('<option>' + property + '</option>'); } } }); }); </script> </head> <body> <form id="myform" action="/rest/services/foo1" method="POST" enctype="multipart/form-data"> <!-- The form does not seem to submit at all if I don't set action to a default value? !--> <select id="selectedaction"> <script type="text/javascript"> </script> </select> <input type="file" value="Choose"/> <input type="submit" value="Submit" /> </form> <div id="response"> </div> </body> </html>

  • embed a jquery script after jquery is loaded by widget

    - by matthew k
    http://stackoverflow.com/a/6065421 was helpful to see how to confirm jquery has been loaded. my widget will need a class that was written using jquery. may i have some assistance on embedding this other class built using jquery? thank you, below is the snippet from the above link with my code added in the final portion as noted in the code comments: (function(window, document, version, callback) { var j, d; var loaded = false; if (!(j = window.jQuery) || version > j.fn.jquery || callback(j, loaded)) { var script = document.createElement("script"); script.type = "text/javascript"; script.src = "/media/jquery.js"; script.onload = script.onreadystatechange = function() { if (!loaded && (!(d = this.readyState) || d == "loaded" || d == "complete")) { callback((j = window.jQuery).noConflict(1), loaded = true); j(script).remove(); } }; document.documentElement.childNodes[0].appendChild(script) } })(window, document, "1.3", function($, jquery_loaded) { //my code added below var script_tag = document.createElement('script'); script_tag.setAttribute("type","text/javascript"); script_tag.setAttribute("src", "http://mysite.com/widget/slides.jquery.js"); (document.getElementsByTagName("head")[0] || document.documentElement).appendChild(script_tag); $('#slides').slides({}); //this line gives an error. }); right now, i am trying the following based on the response(s) provided to this question (line that throws error is noted with a comment): //this function is called after jquery being embedded has been confirmed. {mysite} placeholder is nonexistent in actual code. function main() { jQuery(document).ready(function($) { var css_link = $("<link>", { rel: "stylesheet", type: "text/css", href: "http://mysite/widget/widget.css" }); css_link.appendTo('head'); $('#crf_widget').after('<div id="crf_widget_container"></div>'); /******* Load HTML *******/ var jsonp_url = "http://mysite/widget.php?callback=?"; $.getJSON(jsonp_url, function(data) { $('#crf_widget_container').html(data); $('#category_sel').change(function(){ alert(this.value); }); $.getScript("http://mysite/widget/slides.jquery.js", function(data, textStatus, jqxhr) { alert(1); //fires ok $('#slides').slides({}); //errors }); }); }); }

  • Elements added with appendTo() not immediately available

    - by Zip Gun Jim
    I'm having a problem with elements added with appendTo() not being immediately available in the DOM. First, I'm reading some data from a JSON file and then appending some html to a div. jsonUrl = "js/performers.json"; $.getJSON(jsonUrl, function(json) { $.each(json.performers, function(i, performer) { var html = '<div class="performer_mini">'; html += '<img src="' + performer.thumbnail + '" alt="' + performer.name + '" /><br />'; html += performer.name + '<br /></div>'; $(html).appendTo("div#performer_spotlight"); }); }); Then I'm calling a random shuffler plugin to show one of the added divs at a time. $("#performer_spotlight").randomShuffler(".performer_mini", 3000, 3000, 9000); The random shuffler does the following: (function($) { $.fn.randomShuffler = function(shuffledElements, fadeInTime, fadeOutTime, timeout) { fadeInTime = fadeInTime || 3000; fadeOutTime = fadeOutTime || 3000; timeout = timeout || 9000; $(shuffledElements).hide(); var $old_element; var $new_element; var old_index = 0; var new_index = 0; function shuffleElement() { $old_element = $new_element; old_index = new_index; while ($(shuffledElements).length > 0 && old_index == new_index) { // don't display the same element twice in a row new_index = Math.floor(Math.random()*$(shuffledElements).length); } $new_element = $(shuffledElements + ":eq(" + new_index + ")"); if ($old_element != undefined) { $old_element.fadeOut(fadeOutTime, function() { $new_element.fadeIn(fadeInTime); }); } else { $new_element.fadeIn(fadeInTime); } setTimeout(shuffleElement, timeout); } $(this).show(); shuffleElement(); } })(jQuery); The first time the shuffleElement() function is called $(shuffledElements).length equals 0, so no element is displayed. On the next call to shuffleElement(), the elements added with appendTo() are available and one is selected at random as expected. Everything works correctly after that. Is there some way to refresh the DOM or make these elements available to jQuery immediately after I add them with appendTo()? Any other suggestions for how to accomplish this?

  • Forced closed only when put alphabetical string in edit text

    - by Abdullah Al Mubarok
    So, I make a checker if an id is in the database or not, the id is in numerical string, the type in database is char(6) though. So this is my code public class input extends Activity{ /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.input); final EditText edittext = (EditText)findViewById(R.id.editText1); Button button = (Button)findViewById(R.id.button1); button.setOnClickListener(new OnClickListener(){ @Override public void onClick(View arg0) { // TODO Auto-generated method stub String nopel = edittext.getText().toString(); if(nopel.length() == 0){ Toast.makeText(getApplicationContext(), "error", Toast.LENGTH_SHORT).show(); }else{ List<NameValuePair> pairs = new ArrayList<NameValuePair>(); pairs.add(new BasicNameValuePair("nopel", nopel)); JSON json_dp = new JSON(); JSONObject jobj_dp = json_dp.getJSON("http://10.0.2.2/KP/pdam/nopel.php", pairs); try { if(jobj_dp.getInt("row") == 0){ Toast.makeText(getApplicationContext(), "error", Toast.LENGTH_SHORT).show(); }else{ String snopel = jobj_dp.getString("nopel"); String snama = jobj_dp.getString("nama"); String salamat = jobj_dp.getString("alamat"); String sgolongan = jobj_dp.getString("golongan"); Intent i = new Intent(input.this, list.class); i.putExtra("nopel", snopel); i.putExtra("nama", snama); i.putExtra("alamat", salamat); i.putExtra("golongan", sgolongan); startActivity(i); } } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } }); } } the first check is to check if an input is null, it's going right for now, the second check is to check if an id in the database, and it's the problem. When I try some id in numerical value like "0001" or "02013" it's fine, and can run. but when I just got to put "abushd" it forced close. anyone know why I got this?

    function getItemDialogContent(planItemType) { var oDialogContent = $('<div/>').append($('#cardDialogHelper').html()).addClass("card"); if (planItemType) { oDialogContent.find('#cardDialogHeader').addClass(planItemType).find('#dialogTitle').html(planItemType); oDialogContent.find('#cardDialogCustomFields').html($('#' + planItemType + 'DialogFields').html()); if (planItemType == 'announcement' || planItemType == 'question') { oDialogContent.find("#dialogPin").remove(); } } return oDialogContent; } I am doing some code cleanup for a web application I am working on. The above method lags in IE and most of our user base use IE. Can someone help me. I figure the find() method is very expensive because of the DOM traversal and I am thinking of optimizing. Any ideas anyone? Thanks in advance :D Been doing some profiling on the application and the following line seems to be causing alot of problems. help me please. is there any way I can optimize ? $('').append($('#cardDialogHelper').html()).addClass("card"); This is the ajax call that does the work. Is there a way to do some of this after the call. Please help me. (Added some functions I thought would be helpful in the diagnosis) GetAllPlansTemp = function() { $.getJSON("/SAMPLE/GetAllPlanItems",processData); } processData = function(data) { _throbber = showThrobber(); var sortedPlanItems = $(data.d).sort("Sequence", "asc"); // hideThrobber(_throbber); $(sortedPlanItems).each(createCardSkipTimelime); doCardStacks(); doTimelineFormat(); if (boolViewAblePlans == 'false') { $("p").show(); } hideThrobber(_throbber); } function createCardSkipTimelime() { boolViewAblePlans = 'false'; if (this.__Deleted == 'true' || IsPastPlanItem(this)) { return; } boolViewAblePlans = 'true'; fixer += "\n" + this.TempKey; // fixes what looks like a js threading issue. var value = CreatePlanCard2(this, GetPlanCardStackContainer(this.__type)); UpdatePlanCardNoTimeLine(value, this); } function CreatePlanCard2(carddata, sContainer) { var sCardclass = GetPlanCardClass(carddata.__type); var editdialog = getItemDialogContent(sCardclass); return $('<div/>').attr('id', carddata.TempKey).card({ 'container': $(sContainer), 'cardclass': sCardclass, 'editdialog': editdialog, 'readonly': GetCardMode(carddata) }); }

  • Wishful Thinking: Why can't HTML fix Script Attacks at the Source?

    - by Rick Strahl
    The Web can be an evil place, especially if you're a Web Developer blissfully unaware of Cross Site Script Attacks (XSS). Even if you are aware of XSS in all of its insidious forms, it's extremely complex to deal with all the issues if you're taking user input and you're actually allowing users to post raw HTML into an application. I'm dealing with this again today in a Web application where legacy data contains raw HTML that has to be displayed and users ask for the ability to use raw HTML as input for listings. The first line of defense of course is: Just say no to HTML input from users. If you don't allow HTML input directly and use HTML Encoding (HttyUtility.HtmlEncode() in .NET or using standard ASP.NET MVC output @Model.Content) you're fairly safe at least from the HTML input provided. Both WebForms and Razor support HtmlEncoded content, although Razor makes it the default. In Razor the default @ expression syntax:@Model.UserContent automatically produces HTML encoded content - you actually have to go out of your way to create raw HTML content (safe by default) using @Html.Raw() or the HtmlString class. In Web Forms (V4) you can use:<%: Model.UserContent %> or if you're using a version prior to 4.0:<%= HttpUtility.HtmlEncode(Model.UserContent) %> This works great as a hedge against embedded <script> tags and HTML markup as any HTML is turned into text that displays as HTML but doesn't render the HTML. But it turns any embedded HTML markup tags into plain text. If you need to display HTML in raw form with the markup tags rendering based on user input this approach is worthless. If you do accept HTML input and need to echo the rendered HTML input back, the task of cleaning up that HTML is a complex task. In the projects I work on, customers are frequently asking for the ability to post raw HTML quite frequently.  Almost every app that I've built where there's document content from users we start out with text only input - possibly using something like MarkDown - but inevitably users want to just post plain old HTML they created in some other rich editing application. See this a lot with realtors especially who often want to reuse their postings easily in multiple places. In my work this is a common problem I need to deal with and I've tried dozens of different methods from sanitizing, simple rejection of input to custom markup schemes none of which have ever felt comfortable to me. They work in a half assed, hacked together sort of way but I always live in fear of missing something vital which is *really easy to do*. My Wishlist Item: A <restricted> tag in HTML Let me dream here for a second on how to address this problem. It seems to me the easiest place where this can be fixed is: In the browser. Browsers are actually executing script code so they have a lot of control over the script code that resides in a page. What if there was a way to specify that you want to turn off script code for a block of HTML? The main issue when dealing with HTML raw input isn't that we as developers are unaware of the implications of user input, but the fact that we sometimes have to display raw HTML input the user provides. So the problem markup is usually isolated in only a very specific part of the document. So, what if we had a way to specify that in any given HTML block, no script code could execute by wrapping it into a tag that disables all script functionality in the browser? This would include <script> tags and any document script attributes like onclick, onfocus etc. and potentially also disallow things like iFrames that can potentially be scripted from the within the iFrame's target. I'd like to see something along these lines:<article> <restricted allowscripts="no" allowiframes="no"> <div>Some content</div> <script>alert('go ahead make my day, punk!");</script> <div onfocus="$.getJson('http://evilsite.com/')">more content</div> </restricted> </article> A tag like this would basically disallow all script code from firing from any HTML that's rendered within it. You'd use this only on code that you actually render from your data only and only if you are dealing with custom data. So something like this:<article> <restricted> @Html.Raw(Model.UserContent) </restricted> </article> For browsers this would actually be easy to intercept. They render the DOM and control loading and execution of scripts that are loaded through it. All the browser would have to do is suspend execution of <script> tags and not hookup any event handlers defined via markup in this block. Given all the crazy XSS attacks that exist and the prevalence of this problem this would go a long way towards preventing at least coded script attacks in the DOM. And it seems like a totally doable solution that wouldn't be very difficult to implement by vendors. There would also need to be some logic in the parser to not allow an </restricted> or <restricted> tag into the content as to short-circuit the rstricted section (per James Hart's comment). I'm sure there are other issues to consider as well that I didn't think of in my off-the-back-of-a-napkin concept here but the idea overall seems worth consideration I think. Without code running in a user supplied HTML block it'd be pretty hard to compromise a local HTML document and pass information like Cookies to a server. Or even send data to a server period. Short of an iFrame that can access the parent frame (which is another restriction that should be available on this <restricted> tag) that could potentially communicate back, there's not a lot a malicious site could do. The HTML could still 'phone home' via image links and href links potentially and basically say this site was accessed, but without the ability to run script code it would be pretty tough to pass along critical information to the server beyond that. Ahhhh… one can dream… Not holding my breath of course. The design by committee that is the W3C can't agree on anything in timeframes measured less than decades, but maybe this is one place where browser vendors can actually step up the pressure. This is something in their best interest to reduce the attack surface for vulnerabilities on their browser platforms significantly. Several people commented on Twitter today that there isn't enough discussion on issues like this that address serious needs in the web browser space. Realistically security has to be a number one concern with Web applications in general - there isn't a Web app out there that is not vulnerable. And yet nothing has been done to address these security issues even though there might be relatively easy solutions to make this happen. It'll take time, and it's probably not going to happen in our lifetime, but maybe this rambling thought sparks some ideas on how this sort of restriction can get into browsers in some way in the future.© Rick Strahl, West Wind Technologies, 2005-2012Posted in ASP.NET  HTML5  HTML  Security   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • Populate google.visualization.DataTable for a AnnotatedTimeLine using JSON

    - by Lucifer
    Hi I have a HttpHandler which returns some JSON in (i think) the correct format for a google.visualization.DataTable, but the AnnotatedTimeLine fails to work? This is the JSON returned by the Handler: {cols: [{id: 'DATE', label: 'Date', type: 'date'}, {id: 'KEYWORD51', label: 'vw cheltenham', type: 'number'}, {id: 'KEYWORD52', label: 'volkswagen cheltenham', type: 'number'}, {id: 'KEYWORD61', label: 'vw dealer cheltenham', type: 'number'}], rows: [{c: [{v: new Date(2010, 3, 13)}, {v: 20}, {v: 1}, {v: 2}]}, {c: [{v: new Date(2010, 3, 14)}, {v: 19}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 15)}, {v: 19}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 16)}, {v: 18}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 17)}, {v: 17}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 18)}, {v: 17}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 19)}, {v: 12}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 20)}, {v: 13}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 21)}, {v: 11}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 22)}, {v: 10}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 23)}, {v: 10}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 24)}, {v: 8}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 25)}, {v: 6}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 26)}, {v: 6}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 27)}, {v: 5}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 28)}, {v: 4}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 29)}, {v: 4}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 3, 30)}, {v: 2}, {v: 1}, {v: 1}]}, {c: [{v: new Date(2010, 4, 1)}, {v: 2}, {v: 1}, {v: 1}]}, {c: [{v: new Date(2010, 4, 2)}, {v: 1}, {v: 1}, {v: 1}]}, {c: [{v: new Date(2010, 4, 3)}, {v: 2}, {v: 1}, {v: 1}]}, {c: [{v: new Date(2010, 4, 4)}, {v: 0}, {v: 1}, {v: 1}]}, {c: [{v: new Date(2010, 4, 5)}, {v: 0}, {v: 1}, {v: 1}]}, {c: [{v: new Date(2010, 4, 6)}, {v: 0}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 4, 7)}, {v: 0}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 4, 8)}, {v: 0}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 4, 9)}, {v: 0}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 4, 10)}, {v: 0}, {v: 0}, {v: 0}]}, {c: [{v: new Date(2010, 4, 11)}, {v: 0}, {v: 1}, {v: 1}]}, {c: [{v: new Date(2010, 4, 12)}, {v: 2}, {v: 1}, {v: 1}]}]} This is the Javascript, I used JQuery to get the JSON, have also tried $.getJSON() google.load('visualization', '1', { 'packages': ['annotatedtimeline'] }); google.setOnLoadCallback(loadGraph); function loadGraph() { $.get("/GraphDataHandler.axd", function(response) { drawGraph(response); }); } function drawGraph(response) { var visualization = new google.visualization.AnnotatedTimeLine(document.getElementById('chart_div')); var data = new google.visualization.DataTable(response, 0.6); visualization.draw(data, { title: 'Rankings', titleX: 'Date', titleY: 'Position', displayAnnotations: false, allowRedraw: true }); } But, if I write the same JSON to the page like below it works fine!? <script type="text/javascript"> //<![CDATA[ var gData = {cols: [{id: 'DATE', label: 'Date', type: 'date'}, {id: 'KEYWORD51', label: 'vw cheltenham', type: 'number'}], rows: [{c: [{v: new Date(2010, 3, 13)}, {v: 20}]}, {c: [{v: new Date(2010, 3, 14)}, {v: 19}]}, {c: [{v: new Date(2010, 3, 15)}, {v: 19}]}, {c: [{v: new Date(2010, 3, 16)}, {v: 18}]}, {c: [{v: new Date(2010, 3, 17)}, {v: 17}]}, {c: [{v: new Date(2010, 3, 18)}, {v: 17}]}, {c: [{v: new Date(2010, 3, 19)}, {v: 12}]}, {c: [{v: new Date(2010, 3, 20)}, {v: 13}]}, {c: [{v: new Date(2010, 3, 21)}, {v: 11}]}, {c: [{v: new Date(2010, 3, 22)}, {v: 10}]}, {c: [{v: new Date(2010, 3, 23)}, {v: 10}]}, {c: [{v: new Date(2010, 3, 24)}, {v: 8}]}, {c: [{v: new Date(2010, 3, 25)}, {v: 6}]}, {c: [{v: new Date(2010, 3, 26)}, {v: 6}]}, {c: [{v: new Date(2010, 3, 27)}, {v: 5}]}, {c: [{v: new Date(2010, 3, 28)}, {v: 4}]}, {c: [{v: new Date(2010, 3, 29)}, {v: 4}]}, {c: [{v: new Date(2010, 3, 30)}, {v: 2}]}, {c: [{v: new Date(2010, 4, 1)}, {v: 2}]}, {c: [{v: new Date(2010, 4, 2)}, {v: 1}]}, {c: [{v: new Date(2010, 4, 3)}, {v: 2}]}, {c: [{v: new Date(2010, 4, 4)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 5)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 6)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 7)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 8)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 9)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 10)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 11)}, {v: 0}]}, {c: [{v: new Date(2010, 4, 12)}, {v: 2}]}]}; //]]> </script> Please advise how I can get it to work correctly using a the JSON calls?

  • How to optimize this JSON/JQuery/Javascript function in IE7/IE8?

    - by melaos
    hi guys, i'm using this function to parse this json data but i find the function to be really slow in IE7 and slightly slow in IE8. basically the first listbox generate the main product list, and upon selection of the main list, it will populate the second list. this is my data: [{"ProductCategoryId":209,"ProductCategoryName":"X-Fi","ProductSubCategoryId":668,"ProductSubCategoryName":"External Solutions","ProductId":15913,"ProductName":"Creative Xmod","ProductServiceLifeId":1},{"ProductCategoryId":209,"ProductCategoryName":"X-Fi","ProductSubCategoryId":668,"ProductSubCategoryName":"External Solutions","ProductId":15913,"ProductName":"Creative Xmod","ProductServiceLifeId":1},{"ProductCategoryId":209,"ProductCategoryName":"X-Fi","ProductSubCategoryId":668,"ProductSubCategoryName":"External Solutions","ProductId":18094,"ProductName":"Sound Blaster Wireless Receiver","ProductServiceLifeId":1},{"ProductCategoryId":209,"ProductCategoryName":"X-Fi","ProductSubCategoryId":668,"ProductSubCategoryName":"External Solutions","ProductId":16185,"ProductName":"Xdock Wireless","ProductServiceLifeId":1},{"ProductCategoryId":209,"ProductCategoryName":"X-Fi","ProductSubCategoryId":668,"ProductSubCategoryName":"External Solutions","ProductId":16186,"ProductName":"Xmod Wireless","ProductServiceLifeId":1}] and these are the functions that i'm using: //Three Product Panes function function populateMainPane() { $.getJSON('/Home/ThreePaneProductData/', function(data) { products = data; alert(JSON.stringify(products)); var prodCategory = {}; for (i = 0; i < products.length; i++) { prodCategory[products[i].ProductCategoryId] = products[i].ProductCategoryName; } //end for //take only unique product category to be used var id = 0; for (id in prodCategory) { if (prodCategory.hasOwnProperty(id)) { $(".LBox1").append("<option value='" + id + "'>" + prodCategory[id] + "</option>"); //alert(prodCategory[id]); } } var url = document.location.href; var parms = url.substring(url.indexOf("?") + 1).split("&"); for (var i = 0; i < parms.length; i++) { var parm = parms[i].split("="); if (parm[0].toLowerCase() == "pid") { $(".PanelProductReg").show(); var nProductIds = parm[1].split(","); for (var k = 0; k < nProductIds.length; k++) { var nProductId = parseInt(nProductIds[k], 10); for (var j = 0; j < products.length; j++) { if (nProductId == parseInt(products[j].ProductId, 10)) { addProductRow(nProductId, products[j].ProductName); j = products.length; } } //end for } } } }); } //end function function populateSubCategoryPane() { var subCategory = {}; for (var i = 0; i < products.length; i++) { if (products[i].ProductCategoryId == $('.LBox1').val()) subCategory[products[i].ProductSubCategoryId] = products[i].ProductSubCategoryName; } //end for //clear off the list box first $(".LBox2").html(""); var id = 0; for (id in subCategory) { if (subCategory.hasOwnProperty(id)) { $(".LBox2").append("<option value='" + id + "'>" + subCategory[id] + "</option>"); //alert(prodCategory[id]); } } } //end function is there anything i can do to optimize this or is this a known browser issue?

  • Change form field options dynamically (and restore previously selected options) using jQuery

    - by Martin
    I'm fairly new to both jQuery and JavaScript so can anyone please point out what I'm missing here? I have a form with multiple pairs of select fields, where the content of the second field relies on the selection of the first one. Once a value is chosen from the first one then a piece of jQuery code empties the corresponding second select options, gets new values as JSON and inserts them as new select values. All of this works with the code I've written. However if a user has chosen a second value, I'd like to restore it if possible (meaning if the new values also include the one previously selected). I tried to do this by first saving the second value and then trying to set it once the new options have been inserted. This did not work. However when trying to debug I inserted an alert() just before restoring the second value and with that in there it does work... Am I missing something very basic here? Any help would be appreciated. HTML: <select name="party-0-first" id="id_party-0-first"> <option value="" selected="selected">---------</option> <option value="1">first_value1</option> <option value="2">first_value2</option> <option value="3">first_value3</option> <option value="4">first_value4</option> </select> <select name="party-0-second" id="id_party-0-second"> <option value="" selected="selected">---------</option> <option value="1">second_value1</option> <option value="2">second_value2</option> <option value="3">second_value3</option> <option value="4">second_value4</option> </select> <select name="party-1-first" id="id_party-1-first"> ... JavaScript: $.fn.setSecond = function() { var divName = $(this).attr("name"); divName = divName.replace('-first', ''); divName = divName.replace('party-', ''); // Save the currently selected value of the "second" select box // This seems to work properly setValue = $('#id_party-' + divName + '-second').val(); // Get the new values $.getJSON("/json_opsys/", { client: $(this).val() }, function(data){ $('#id_party-' + divName + '-second').empty(); $('#id_party-' + divName + '-second').append('<option value="" selected="selected">---------</option>'); $.each(data, function(i, item){ $('#id_party-' + divName + '-second').append('<option value="' + item.pk + '">' + item.fields.name + '</option>'); }); }); // Here I try to restore the selected value // This does not work normally, however if I place a javascript alert() before // this for some reason it does work $('#id_party-' + divName + '-second').val(setValue); $(document).ready(function(){ $('[id*=first]').change(function() { $(this).setSecond(); }); });

  • jQuery , Trigger change event on newly created elements

    - by kwhohasamullet
    Hi Guys, I have a button in a form that when clicked adds another set of form fields, In these form fields there are 2 drop downs where the contents of the 2nd dropdown rely on what is selected in the first dropdown... What i want to do is when the new form field button is clicked for the new items to be added and then the change event to be triggered on the drop down that was created so what only that drop down changes and not all the drop downs with the same name currently in that form. THe first drop down is called product Category The code for the addFormField function is: function addFormField() { var id = document.getElementById("field_id").value; $("#products").append("<table width='600' cellpadding='5' cellspacing='0' class='Add_Products' id='row" + id + "'><td width='250' class='left'><label>Select Product Category</label></td><td class='right' ><label><select name='" + id + "' id='ProductCategory'><?php foreach($categories as $key=>$category){ echo "<option value=".$key.">".$category."</option>"; } ?></select></label></td></tr><tr><td width='250' class='left'><label>Select Product Template</label></td><td class='right' ><label><select name='data[QuoteItem][" + id + "][product_id]' id='QuoteItem" + id + "product_id' class='Product' title='" + id + "'></select></label></td></tr><tr ><td class='left'>Name</td><td class='right'><label><input name='data[QuoteItem][" + id + "][name]' type='text' id='QuoteItem" + id + "name' size='50' /></label></td></tr><tr ><td class='left'>Price (ex GST)</td><td class='right'><input type='text' name='data[QuoteItem][" + id + "][price]' id='QuoteItem" + id + "price' onchange='totalProductPrice();' class='quote-item-price' value='0' /></td></tr><tr><td class='left'>Description</td><td class='right'><label><textarea name='data[QuoteItem][" + id + "][description]' cols='38' rows='5' id='QuoteItem" + id + "description'></textarea></label></td></tr><tr><td><a href='#' onClick='removeFormField(\"#row" + id + "\"); return false;'>Remove</a></td></tr></table>"); $('#row' + id).highlightFade({ speed:1000 }); id = (id - 1) + 2; document.getElementById("field_id").value = id; } The code that detects change in ProductCategory dropdown and triggers the AJAX is below: $("select#ProductCategory").live('change', function(){ var url = base + "/quotes/productList/" + $(this).val() + ""; var id = $(this).attr('name'); $.getJSON(url,{id: $(this).val(), ajax: 'true'}, function(j){ var options = ''; options += '<option value="0">None</option>'; $.each(j, function(key, value){ options += '<option value="' + key + '">' + value + '</option>'; }) $("select#QuoteItem" + id + "product_id").html(options); }) }).trigger('change'); I have been trying all afternoon to work this out and the closest one i got to work applied the returned ajax values to all items. Currently using the live function people can add new fields and are able to use the drops down independant of each other dropdown but its only when the field is first added that i have trouble getting is populated Thanks in advance for any help

    - by user303518
    Hi guys, I'm trying to make a request/reply section in my project. I want to achieve these functionality in that code (that I'm not able to implement; so guys please help me out): 1 When user click on reply button; other reply area(text-area +button) should be hide (means at a time only one reply area should be visible to the user). 2 when user click on reply button text-area will focus and page will slide down (suppose user reply 10 comment focus will automatically set to the 10 number text area and page will slide down to that position accordingly).

  • Creating a JSONP Formatter for ASP.NET Web API

    - by Rick Strahl
    Out of the box ASP.NET WebAPI does not include a JSONP formatter, but it's actually very easy to create a custom formatter that implements this functionality. JSONP is one way to allow Browser based JavaScript client applications to bypass cross-site scripting limitations and serve data from the non-current Web server. AJAX in Web Applications uses the XmlHttp object which by default doesn't allow access to remote domains. There are number of ways around this limitation <script> tag loading and JSONP is one of the easiest and semi-official ways that you can do this. JSONP works by combining JSON data and wrapping it into a function call that is executed when the JSONP data is returned. If you use a tool like jQUery it's extremely easy to access JSONP content. Imagine that you have a URL like this: http://RemoteDomain/aspnetWebApi/albums which on an HTTP GET serves some data - in this case an array of record albums. This URL is always directly accessible from an AJAX request if the URL is on the same domain as the parent request. However, if that URL lives on a separate server it won't be easily accessible to an AJAX request. Now, if  the server can serve up JSONP this data can be accessed cross domain from a browser client. Using jQuery it's really easy to retrieve the same data with JSONP:function getAlbums() { $.getJSON("http://remotedomain/aspnetWebApi/albums?callback=?",null, function (albums) { alert(albums.length); }); } The resulting callback the same as if the call was to a local server when the data is returned. jQuery deserializes the data and feeds it into the method. Here the array is received and I simply echo back the number of items returned. From here your app is ready to use the data as needed. This all works fine - as long as the server can serve the data with JSONP. What does JSONP look like? JSONP is a pretty simple 'protocol'. All it does is wrap a JSON response with a JavaScript function call. The above result from the JSONP call looks like this:Query17103401925975181569_1333408916499( [{"Id":"34043957","AlbumName":"Dirty Deeds Done Dirt Cheap",…},{…}] ) The way JSONP works is that the client (jQuery in this case) sends of the request, receives the response and evals it. The eval basically executes the function and deserializes the JSON inside of the function. It's actually a little more complex for the framework that does this, but that's the gist of what happens. JSONP works by executing the code that gets returned from the JSONP call. JSONP and ASP.NET Web API As mentioned previously, JSONP support is not natively in the box with ASP.NET Web API. But it's pretty easy to create and plug-in a custom formatter that provides this functionality. The following code is based on Christian Weyers example but has been updated to the latest Web API CodePlex bits, which changes the implementation a bit due to the way dependent objects are exposed differently in the latest builds. Here's the code:  using System; using System.IO; using System.Net; using System.Net.Http.Formatting; using System.Net.Http.Headers; using System.Threading.Tasks; using System.Web; using System.Net.Http; namespace Westwind.Web.WebApi { /// <summary> /// Handles JsonP requests when requests are fired with /// text/javascript or application/json and contain /// a callback= (configurable) query string parameter /// /// Based on Christian Weyers implementation /// https://github.com/thinktecture/Thinktecture.Web.Http/blob/master/Thinktecture.Web.Http/Formatters/JsonpFormatter.cs /// </summary> public class JsonpFormatter : JsonMediaTypeFormatter { public JsonpFormatter() { SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/json")); SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/javascript")); //MediaTypeMappings.Add(new UriPathExtensionMapping("jsonp", "application/json")); JsonpParameterName = "callback"; } /// <summary> /// Name of the query string parameter to look for /// the jsonp function name /// </summary> public string JsonpParameterName {get; set; } /// <summary> /// Captured name of the Jsonp function that the JSON call /// is wrapped in. Set in GetPerRequestFormatter Instance /// </summary> private string JsonpCallbackFunction; public override bool CanWriteType(Type type) { return true; } /// <summary> /// Override this method to capture the Request object /// and look for the query string parameter and /// create a new instance of this formatter. /// /// This is the only place in a formatter where the /// Request object is available. /// </summary> /// <param name="type"></param> /// <param name="request"></param> /// <param name="mediaType"></param> /// <returns></returns> public override MediaTypeFormatter GetPerRequestFormatterInstance(Type type, HttpRequestMessage request, MediaTypeHeaderValue mediaType) { var formatter = new JsonpFormatter() { JsonpCallbackFunction = GetJsonCallbackFunction(request) }; return formatter; } /// <summary> /// Override to wrap existing JSON result with the /// JSONP function call /// </summary> /// <param name="type"></param> /// <param name="value"></param> /// <param name="stream"></param> /// <param name="contentHeaders"></param> /// <param name="transportContext"></param> /// <returns></returns> public override Task WriteToStreamAsync(Type type, object value, Stream stream, HttpContentHeaders contentHeaders, TransportContext transportContext) { if (!string.IsNullOrEmpty(JsonpCallbackFunction)) { return Task.Factory.StartNew(() => { var writer = new StreamWriter(stream); writer.Write( JsonpCallbackFunction + "("); writer.Flush(); base.WriteToStreamAsync(type, value, stream, contentHeaders, transportContext).Wait(); writer.Write(")"); writer.Flush(); }); } else { return base.WriteToStreamAsync(type, value, stream, contentHeaders, transportContext); } } /// <summary> /// Retrieves the Jsonp Callback function /// from the query string /// </summary> /// <returns></returns> private string GetJsonCallbackFunction(HttpRequestMessage request) { if (request.Method != HttpMethod.Get) return null; var query = HttpUtility.ParseQueryString(request.RequestUri.Query); var queryVal = query[this.JsonpParameterName]; if (string.IsNullOrEmpty(queryVal)) return null; return queryVal; } } } Note again that this code will not work with the Beta bits of Web API - it works only with post beta bits from CodePlex and hopefully this will continue to work until RTM :-) This code is a bit different from Christians original code as the API has changed. The biggest change is that the Read/Write functions no longer receive a global context object that gives access to the Request and Response objects as the older bits did. Instead you now have to override the GetPerRequestFormatterInstance() method, which receives the Request as a parameter. You can capture the Request there, or use the request to pick up the values you need and store them on the formatter. Note that I also have to create a new instance of the formatter since I'm storing request specific state on the instance (information whether the callback= querystring is present) so I return a new instance of this formatter. Other than that the code should be straight forward: The code basically writes out the function pre- and post-amble and the defers to the base stream to retrieve the JSON to wrap the function call into. The code uses the Async APIs to write this data out (this will take some getting used to seeing all over the place for me). Hooking up the JsonpFormatter Once you've created a formatter, it has to be added to the request processing sequence by adding it to the formatter collection. Web API is configured via the static GlobalConfiguration object.  protected void Application_Start(object sender, EventArgs e) { // Verb Routing RouteTable.Routes.MapHttpRoute( name: "AlbumsVerbs", routeTemplate: "albums/{title}", defaults: new { title = RouteParameter.Optional, controller = "AlbumApi" } ); GlobalConfiguration .Configuration .Formatters .Insert(0, new Westwind.Web.WebApi.JsonpFormatter()); }   That's all it takes. Note that I added the formatter at the top of the list of formatters, rather than adding it to the end which is required. The JSONP formatter needs to fire before any other JSON formatter since it relies on the JSON formatter to encode the actual JSON data. If you reverse the order the JSONP output never shows up. So, in general when adding new formatters also try to be aware of the order of the formatters as they are added.

  • Metro: Promises

    - by Stephen.Walther
    The goal of this blog entry is to describe the Promise class in the WinJS library. You can use promises whenever you need to perform an asynchronous operation such as retrieving data from a remote website or a file from the file system. Promises are used extensively in the WinJS library. Asynchronous Programming Some code executes immediately, some code requires time to complete or might never complete at all. For example, retrieving the value of a local variable is an immediate operation. Retrieving data from a remote website takes longer or might not complete at all. When an operation might take a long time to complete, you should write your code so that it executes asynchronously. Instead of waiting for an operation to complete, you should start the operation and then do something else until you receive a signal that the operation is complete. An analogy. Some telephone customer service lines require you to wait on hold – listening to really bad music – until a customer service representative is available. This is synchronous programming and very wasteful of your time. Some newer customer service lines enable you to enter your telephone number so the customer service representative can call you back when a customer representative becomes available. This approach is much less wasteful of your time because you can do useful things while waiting for the callback. There are several patterns that you can use to write code which executes asynchronously. The most popular pattern in JavaScript is the callback pattern. When you call a function which might take a long time to return a result, you pass a callback function to the function. For example, the following code (which uses jQuery) includes a function named getFlickrPhotos which returns photos from the Flickr website which match a set of tags (such as “dog” and “funny”): function getFlickrPhotos(tags, callback) { $.getJSON( "http://api.flickr.com/services/feeds/photos_public.gne?jsoncallback=?", { tags: tags, tagmode: "all", format: "json" }, function (data) { if (callback) { callback(data.items); } } ); } getFlickrPhotos("funny, dogs", function(data) { $.each(data, function(index, item) { console.log(item); }); }); The getFlickr() function includes a callback parameter. When you call the getFlickr() function, you pass a function to the callback parameter which gets executed when the getFlicker() function finishes retrieving the list of photos from the Flickr web service. In the code above, the callback function simply iterates through the results and writes each result to the console. Using callbacks is a natural way to perform asynchronous programming with JavaScript. Instead of waiting for an operation to complete, sitting there and listening to really bad music, you can get a callback when the operation is complete. Using Promises The CommonJS website defines a promise like this (http://wiki.commonjs.org/wiki/Promises): “Promises provide a well-defined interface for interacting with an object that represents the result of an action that is performed asynchronously, and may or may not be finished at any given point in time. By utilizing a standard interface, different components can return promises for asynchronous actions and consumers can utilize the promises in a predictable manner.” A promise provides a standard pattern for specifying callbacks. In the WinJS library, when you create a promise, you can specify three callbacks: a complete callback, a failure callback, and a progress callback. Promises are used extensively in the WinJS library. The methods in the animation library, the control library, and the binding library all use promises. For example, the xhr() method included in the WinJS base library returns a promise. The xhr() method wraps calls to the standard XmlHttpRequest object in a promise. The following code illustrates how you can use the xhr() method to perform an Ajax request which retrieves a file named Photos.txt: var options = { url: "/data/photos.txt" }; WinJS.xhr(options).then( function (xmlHttpRequest) { console.log("success"); var data = JSON.parse(xmlHttpRequest.responseText); console.log(data); }, function(xmlHttpRequest) { console.log("fail"); }, function(xmlHttpRequest) { console.log("progress"); } ) The WinJS.xhr() method returns a promise. The Promise class includes a then() method which accepts three callback functions: a complete callback, an error callback, and a progress callback: Promise.then(completeCallback, errorCallback, progressCallback) In the code above, three anonymous functions are passed to the then() method. The three callbacks simply write a message to the JavaScript Console. The complete callback also dumps all of the data retrieved from the photos.txt file. Creating Promises You can create your own promises by creating a new instance of the Promise class. The constructor for the Promise class requires a function which accepts three parameters: a complete, error, and progress function parameter. For example, the code below illustrates how you can create a method named wait10Seconds() which returns a promise. The progress function is called every second and the complete function is not called until 10 seconds have passed: (function () { "use strict"; var app = WinJS.Application; function wait10Seconds() { return new WinJS.Promise(function (complete, error, progress) { var seconds = 0; var intervalId = window.setInterval(function () { seconds++; progress(seconds); if (seconds > 9) { window.clearInterval(intervalId); complete(); } }, 1000); }); } app.onactivated = function (eventObject) { if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) { wait10Seconds().then( function () { console.log("complete") }, function () { console.log("error") }, function (seconds) { console.log("progress:" + seconds) } ); } } app.start(); })(); All of the work happens in the constructor function for the promise. The window.setInterval() method is used to execute code every second. Every second, the progress() callback method is called. If more than 10 seconds have passed then the complete() callback method is called and the clearInterval() method is called. When you execute the code above, you can see the output in the Visual Studio JavaScript Console. Creating a Timeout Promise In the previous section, we created a custom Promise which uses the window.setInterval() method to complete the promise after 10 seconds. We really did not need to create a custom promise because the Promise class already includes a static method for returning promises which complete after a certain interval. The code below illustrates how you can use the timeout() method. The timeout() method returns a promise which completes after a certain number of milliseconds. WinJS.Promise.timeout(3000).then( function(){console.log("complete")}, function(){console.log("error")}, function(){console.log("progress")} ); In the code above, the Promise completes after 3 seconds (3000 milliseconds). The Promise returned by the timeout() method does not support progress events. Therefore, the only message written to the console is the message “complete” after 10 seconds. Canceling Promises Some promises, but not all, support cancellation. When you cancel a promise, the promise’s error callback is executed. For example, the following code uses the WinJS.xhr() method to perform an Ajax request. However, immediately after the Ajax request is made, the request is cancelled. // Specify Ajax request options var options = { url: "/data/photos.txt" }; // Make the Ajax request var request = WinJS.xhr(options).then( function (xmlHttpRequest) { console.log("success"); }, function (xmlHttpRequest) { console.log("fail"); }, function (xmlHttpRequest) { console.log("progress"); } ); // Cancel the Ajax request request.cancel(); When you run the code above, the message “fail” is written to the Visual Studio JavaScript Console. Composing Promises You can build promises out of other promises. In other words, you can compose promises. There are two static methods of the Promise class which you can use to compose promises: the join() method and the any() method. When you join promises, a promise is complete when all of the joined promises are complete. When you use the any() method, a promise is complete when any of the promises complete. The following code illustrates how to use the join() method. A new promise is created out of two timeout promises. The new promise does not complete until both of the timeout promises complete: WinJS.Promise.join([WinJS.Promise.timeout(1000), WinJS.Promise.timeout(5000)]) .then(function () { console.log("complete"); }); The message “complete” will not be written to the JavaScript Console until both promises passed to the join() method completes. The message won’t be written for 5 seconds (5,000 milliseconds). The any() method completes when any promise passed to the any() method completes: WinJS.Promise.any([WinJS.Promise.timeout(1000), WinJS.Promise.timeout(5000)]) .then(function () { console.log("complete"); }); The code above writes the message “complete” to the JavaScript Console after 1 second (1,000 milliseconds). The message is written to the JavaScript console immediately after the first promise completes and before the second promise completes. Summary The goal of this blog entry was to describe WinJS promises. First, we discussed how promises enable you to easily write code which performs asynchronous actions. You learned how to use a promise when performing an Ajax request. Next, we discussed how you can create your own promises. You learned how to create a new promise by creating a constructor function with complete, error, and progress parameters. Finally, you learned about several advanced methods of promises. You learned how to use the timeout() method to create promises which complete after an interval of time. You also learned how to cancel promises and compose promises from other promises.

  • Why is JSON outputting out of order?

    - by dcp3450
    I'm am trying to get a list of weather information for 8 locations. I'm using a weather API that accepts longitude and latitude and spits back json output with the weather info for that location. I feed the coords in order 0-7 but when json processes the data it comes back in a seemingly random order. I assume it's because some process faster than others and json is outputing what it gets back as it gets it. The output is correct, only the order is wrong. var loc = null; var body = ""; var campuses = new Array(8); campuses[0] = "34.47242,-84.42489,1"; campuses[1] = "33.81488,-84.62048,2"; campuses[2] = "34.27502,-84.46976,3"; campuses[3] = "33.92987,-84.55065,4"; campuses[4] = "34.03433,-84.46723,5"; campuses[5] = "34.08362,-84.67115,6"; campuses[6] = "33.91124,-84.82634,7"; campuses[7] = "34.10409,-84.51804,8"; function getWeather(campusArray) { body += '<p class="topTitle">Campus Weather</p>'; var cSplit = new Array(); cSplit = campusArray.split(','); var loc = "http://www.worldweatheronline.com/feed/weather.ashx?q="+cSplit[0]+","+cSplit[1]+"&format=json&num_of_days=2&key=0a05fff921162948110401&callback=?"; $('#content').html('asdf'); $.getJSON(loc,function(js) { var data = js.data; var humidity = data.current_condition[0].humidity; var tempF = data.current_condition[0].temp_F; var iconDESC = data.current_condition[0].weatherDesc[0].value; var iconURL = data.current_condition[0].weatherIconUrl[0].value; var windDir = data.current_condition[0].winddir16Point; var windSpeed = data.current_condition[0].windspeedMiles; var tempMaxF = data.weather[0].tempMaxF; var tempMinF = data.weather[0].tempMinF; body += '<p class="title">'+cSplit[2]+'</p>'+ '<span class="body">'+tempF+ ' '+windSpeed+ '<img src="'+iconURL+'" /></span>'; $('#content').html(body); }); } getWeather(campuses[0]); getWeather(campuses[1]); getWeather(campuses[2]); getWeather(campuses[3]); getWeather(campuses[4]); getWeather(campuses[5]); getWeather(campuses[6]); getWeather(campuses[7]); I have also tried it as $.ajax var loc = null; var body = ""; var campuses = new Array(8); campuses[0] = "34.47242,-84.42489,1"; campuses[1] = "33.81488,-84.62048,2"; campuses[2] = "34.27502,-84.46976,3"; campuses[3] = "33.92987,-84.55065,4"; campuses[4] = "34.03433,-84.46723,5"; campuses[5] = "34.08362,-84.67115,6"; campuses[6] = "33.91124,-84.82634,7"; campuses[7] = "34.10409,-84.51804,8"; function getWeather(campusArray) { body += '<p class="topTitle">Campus Weather</p>'; var cSplit = new Array(); cSplit = campusArray.split(','); var loc = "http://www.worldweatheronline.com/feed/weather.ashx?q="+cSplit[0]+","+cSplit[1]+"&format=json&num_of_days=2&key=0a05fff921162948110401&callback=?"; $.ajax({ url: loc, async: true, dataType: "json", success: function(js) { var data = js.data; var humidity = data.current_condition[0].humidity; var tempF = data.current_condition[0].temp_F; var iconDESC = data.current_condition[0].weatherDesc[0].value; var iconURL = data.current_condition[0].weatherIconUrl[0].value; var windDir = data.current_condition[0].winddir16Point; var windSpeed = data.current_condition[0].windspeedMiles; var tempMaxF = data.weather[0].tempMaxF; var tempMinF = data.weather[0].tempMinF; body += '<p class="title">'+cSplit[2]+'</p>'+ '<span class="body">'+tempF+ ' '+windSpeed+ '<img src="'+iconURL+'" /></span>'; $('#content').html(body); } }); } getWeather(campuses[0]); getWeather(campuses[1]); getWeather(campuses[2]); getWeather(campuses[3]); getWeather(campuses[4]); getWeather(campuses[5]); getWeather(campuses[6]); getWeather(campuses[7]); EDIT: example of json output: { "data": { "current_condition": [ {"cloudcover": "100", "humidity": "93", "observation_time": "04:04 PM", "precipMM": "0.0", "pressure": "1009", "temp_C": "2", "temp_F": "36", "visibility": "8", "weatherCode": "116", "weatherDesc": [ {"value": "Mist" } ], "weatherIconUrl": [ {"value": "http:\/\/www.worldweatheronline.com\/images\/wsymbols01_png_64\/wsymbol_0006_mist.png" } ], "winddir16Point": "WNW", "winddirDegree": "290", "windspeedKmph": "7", "windspeedMiles": "4" } ], "request": [ {"query": "Lat 34.47 and Lon -84.42", "type": "LatLon" } ], "weather": [ {"date": "2011-01-06", "precipMM": "9.3", "tempMaxC": "7", "tempMaxF": "45", "tempMinC": "2", "tempMinF": "35", "weatherCode": "113", "weatherDesc": [ {"value": "Sunny" } ], "weatherIconUrl": [ {"value": "http:\/\/www.worldweatheronline.com\/images\/wsymbols01_png_64\/wsymbol_0001_sunny.png" } ], "winddir16Point": "WNW", "winddirDegree": "293", "winddirection": "WNW", "windspeedKmph": "20", "windspeedMiles": "13" }, {"date": "2011-01-07", "precipMM": "0.0", "tempMaxC": "6", "tempMaxF": "44", "tempMinC": "0", "tempMinF": "31", "weatherCode": "116", "weatherDesc": [ {"value": "Partly Cloudy" } ], "weatherIconUrl": [ {"value": "http:\/\/www.worldweatheronline.com\/images\/wsymbols01_png_64\/wsymbol_0002_sunny_intervals.png" } ], "winddir16Point": "WNW", "winddirDegree": "286", "winddirection": "WNW", "windspeedKmph": "25", "windspeedMiles": "16" } ] }}

    [Ruby on Rails DataTable guide][1]https://github.com/phronos/rails_datatables/blob/master/README.md I"m following the above and have installed the git plugin as well.
