  • Work with AJAX response with DOM methods

    - by Stomped
    I'm retrieving an entire HTML document via AJAX - and that works fine. But I need to extract certain parts of that document and do things with them. Using a framework (jquery, mootools, etc) is not an option. The only solution I can think of is to grab the body of the HTML document with a regex (yes, I know, terrible) ie. <body>(.*)</body> put that into the current page's DOM in a hidden element, and work with it from there. Is there an easier/better way? Update I've done some testing, and inserting an entire HTML document into a created element behaves a bit differently across browsers I've tested. For example: FF3.5: keeps the contents of the HEAD and BODY tags IE7 / Safari4: Only includes what's between ... Opera 10.10: Keeps HEAD and everything inside it, Keeps contents of BODY The behavior of IE7 and Safari are ideal, but different browsers are doing this differently. Since I'm loading a predetermined HTML document I think I'm going to use the regEx to grab what I want and insert it into a DOM element - unless someone has other suggestions.

  • Mootools periodical funcion and time rewind

    - by hsz
    Hello ! I have some function taht is caller periodically: var func = function() { alert('Hello world!'); }; func.periodical(5000); This function is also called with click event: $('element').addEvent('click', function(){ func(); }); The timer starts and counts 2500msec, then I click $('element'), func() is executed and I want right now to reset the timer that func() will not be called in next 2500msec but in following 5000msec. How to do that ?

  • jQuery encoding values differently than expected for jQuery.ajax data elements

    - by Adam Tuttle
    I'm using jQuery.ajax() to make a PUT request to a REST web service, but seeing some really strange serialization behavior. (Before you say it: Yes, I know that not all browsers support PUT -- this is just an example implementation for an api/framework, and ultimately will not be called by a browser, but rather by a server-side library that does support the extra http verbs.) Here's the form: <form action="/example/api/artist" method="put" id="update"> First Name: <input type="text" name="firstname" /><br/> Last Name: <input type="text" name="lastname" /><br/> Address: <input type="text" name="address" /><br/> City: <input type="text" name="city" /><br/> State: <input type="text" name="state" /><br/> Postal Code: <input type="text" name="postalcode" /><br/> Email: <input type="text" name="email" /><br/> Phone: <input type="text" name="phone" /><br/> Fax: <input type="text" name="fax" /><br/> Password: <input type="text" name="thepassword" /><br/> <input type="hidden" name="debug" value="true" /> <input type="submit" value="Update Artist" /> <input type="reset" value="Cancel" id="updateCancel" /> </form> And the JS: $("#update").submit(function(e){ e.preventDefault(); var frm = $(this); $.ajax({ url: frm.attr('action'), data:{ firstname: $("#update input[name=firstname]").val(), lastname: $("#update input[name=lastname]").val(), address: $("#update input[name=address]").val(), city: $("#update input[name=city]").val(), state: $("#update input[name=state]").val(), postalcode: $("#update input[name=postalcode]").val(), email: $("#update input[name=email]").val(), phone: $("#update input[name=phone]").val(), fax: $("#update input[name=fax]").val(), thepassword: $("#update input[name=thepassword]").val() }, type: frm.attr('method'), dataType: "json", contentType: "application/json", success: function (data, textStatus, xhr){ console.log(data); reloadData(); }, error: function (xhr, textStatus, err){ console.log(textStatus); console.log(err); } }); }); When using FireBug, I see the request go through as this: firstname=Austin&lastname=Weber&address=25463+Main+Street%2C+Suite+C&city=Berkeley&state=CA&postalcode=94707-4513&email=austin%40life.com&phone=555-513-4318&fax=510-513-4888&thepassword=nopolyes That's not horrible, but ideally I'd rather get %20 instead of + for spaces. I tried wrapping each field value lookup in an escape: firstname: escape($("#update input[name=firstname]").val()) But that makes things worse: firstname=Austin&lastname=Weber&address=25463%2520Main%2520Street%252C%2520Suite%2520C&city=Berkeley&state=CA&postalcode=94707-4513&email=austin%40life.com&phone=555-513-4318&fax=510-513-4888&thepassword=nopolyes In this case, the value is being escaped twice; so first the space is encoded to %20, and then the % sign is escaped to %25 resulting in the %2520 for spaces, and %252C for the comma in the address field. What am I doing wrong here?

  • Controlling a browser from Python

    - by Noio
    I am looking for a way to control a browser from Python, i.e. fill out form fields and submit them, possibly call JS functions. I've looked around a bit, but as far as I could see PyWebKitGtk only lets you show the browser as a GUI element, not interface with it. Is there a way to do this easily? I wrote my program logic in Python, and I would hate to port it to JS. Besides that, even if I'd use pure JS "bookmarklets", those wouldn't be able to read/write to my local filesystem, would they? P.S. to quell your suspicions, I'm not trying to automatically fill out forum account creation forms or something similarly spammious, though the task is technically similar. I need to crawl/scrape sites for my research project.

  • How can I wait for the image to load in my new window before printing via child.print()?

    - by libertas
    $("#print").on('click', function () { var child = window.open("image.jpg", "_blank", "location=0,toolbar=0,scrollbars=1,fullscreen=1,menubar=0"); //any way to know/wait for image to load? child.print(); }); Any way for my parent window to know that the child window has completed loading the image prior to calling .print()? If they were trigger happy they would end up printing a blank page. I've tried both: child.attachEvent("onload", function () { child.print(); }); and child.attachEvent("DOMContentLoaded", function () { child.print(); }); //(found this online, apparently it's Firefox only, still didn't work)

  • element height after content change

    - by Neph
    I have a snippet of code that alters the contents of a DIV to match the contents of a textarea and then applies the height change in the DIV to the textarea element. function growTextArea(parameter) { $('div').find("[data-fieldid='1_description']").text($(parameter).val()); // No Works height = $('.hiddenDiv').find("[data-fieldid='1_description']").outerHeight(); alert(height); // Works heightDiv = $('.hiddenDiv').outerHeight(); alert(heightDiv); $(parameter).css('height', $('div').find("[data-fieldid='1_description']").outerHeight()); } The DIV contents change properly, so the search function is working properly, however the search function always returns the original height of the DIV. The function is called by onKeyUp in the textarea. If the .find is swapped out for a .hiddenDiv the height change is reflected properly.

  • Interpolation on Cubism graphs

    - by Abe Stanway
    Cubism was designed, by mbostock's own words, for maximum information density - which means it generally wants to display one datapoint per pixel. While this is useful in many cases, it doesn't help when your data itself is not that dense. In these cases, you get ugly, staccato-style graphs like so: Is there a way to interpolate my data/graph within Cubism to show a nice, smoothed graph? EDIT: After adding keepLastValue to the metric, I get this: Here is the same data as shown in Graphite: I would like to smooth the Cubism view to look more like Graphite (with the added awesomeness of the horizon overplotting)

  • Internet Explore works very slowly executing JS code

    - by Sergey Basharov
    There is a page that uses PHP to fetch search results from Google Search API and then it puts the results on the page some funny way in a circle. Code and may look crappy but seems that it works more or less fine in Firefox. When you enter a search query and click submit button or Next/Previous links, it fills the wheel with results. The problem is its work in IE. It works there very slowly and then it doesn't clear the wheel before filling in new data, but puts it over that. My friend asked me to help him with this code. Please give me a piece of advice how I can fix it. Thanks so much!

What is wrong here?

  • In an array of buttons, how can you tell which button was clicked?

    - by Michael Seltenreich
    If I have an array of buttons, how can I tell which button was clicked? example below var i=0 CreateButton = new function () { savebutton[i]=NewButton() i++ } every time a user runs the function a new button is generated. the first button is savebutton[0] the second is savebutton[1] and so on potentially infinity times. when later the user presses the button I want the screen to alert it's index number (or 'i'). is there any way to make this work in arrays?

  • stop cript debug error dialogs occur in ie8 ?

    - by Haroldo
    I get this, clicking 'no' means the page displays flawlessly. it's refering to this part of jquery1.4.2.js: // Get the Nth element in the matched element set OR // Get the whole matched element set as a clean array get: function( num ) { return num == null ? // Return a 'clean' array this.toArray() : // Return just the object ( num < 0 ? this.slice(num)[ 0 ] : this[ num ] ); }, I assume i'm calling something in the wrong context somewhere in one of my js files (which would be a real mission to find). Will standard IE8 users get this error? (i imagine ms make it pretty difficult to reinstall ie!)

  • mootools event listener disappears after element.innerHTML is changed

    - by baiano
    I putting together a page that will display a set of stored values. I am using mootools and AJAX calls to update the values without needing to refresh the page each time the user selects a new item from the drop down menus. the HTML each line looks something like: <div class="selections"> <input class="checkbox selector" type="checkbox" CHECKED /> <span class="b_name"> <select class="b_n selector"> <!-- options --> </select> </span> <span class="b_level"> <select class="b_l selector"> <!-- options --> </select> </span> <span class="values"> <!-- the values --> </span> In the head I have set up an event listener like: $$('.selector').addEvent('change', function(event){changeValues(this);}); My problem is that when the "b_name" select changes I have to update the list of options in the "b_level" select. I accomplish that by getting a list of the possible options from my database through a php script on another page and replacing "b_level"'s innerHTML. Once I do that, the event listener attached to "b_l selector" no longer works. I tried to resolve this issue by explicitly attaching an event listener to "b_l selector" each time "b_name" changes like so: row.getElement('.b_l').addEvent('change', function(event){changeValues(row.getElement('.b_l'));}); where 'row' is the html element 'div.selections'. It still isn't working and I have no idea what's going on. Can anyone offer a suggestion as to how I can get this resolved? or perhaps a better way to do what I'm doing. Thanks

  • Can I access an iframe of the same domain in a separate window?

    - by jozecuervo
    How can I detect the presence of and then call a function on a frame that is already loaded in one tab (my iframed facebook app) from a page being loaded in a new tab (from an ad-served link). It seems most examples focus on parent/child iframe communication. In this case, a link will be served from Google Ad Manager, which only allows _top or _blank to be targeted. I want to pass an id through the ad click into the new page/tab on my domain and then JS call over to the frame my app is in to switch state. Both frames are on my domain but not in the same document or window. Is this possible?

  • Get client timezone (not GMT offset amount) in JS

    - by Rex M
    I need to determine the client timezone (e.g. CET, GMT, EST) in JS. Getting the offset is straightforward, but doesn't have all the info necessary to determine the TZ, at least not easily. I have a feeling it might be possible to use a combination of offset, whether DST is in use and in effect, etc. but I'm hoping someone else has done the work already, especially considering the weird exceptions when dealing with time. This question is similar but both the question and the answer are based on the (incorrect) assumption every browser's DateString format includes the name of the timezone - which it does not. That is an implementation detail. So, with that I am currently stuck.

  • How to retain focus on an editable html after deleting an element.

    - by Lukasz
    Hello, I have a website with design mode on (aka. content editable = true) with some basic text on it. To that site I hooked up a shortcut so that at any point in the text I can insert an input box that serves me as an autocomplete. For that input however I want it to disappear right after I hit ENTER so that I can continue typing. It is an easy task to just make the input box disappear but I always loose focus from my document. I would greatly appreciate any suggestions on how to make this work?
