  • REST API Best practice: How to accept as input a list of parameter values

    - by whatupwilly
    Hi All, We are launching a new REST API and I wanted some community input on best practices around how we should have input parameters formatted: Right now, our API is very JSON-centric (only returns JSON). The debate of whether we want/need to return XML is a separate issue. As our API output is JSON centric, we have been going down a path where our inputs are a bit JSON centric and I've been thinking that may be convenient for some but weird in general. For example, to get a few product details where multiple products can be pulled at once we currently have: http://our.api.com/Product?id=["101404","7267261"] Should we simplify this as: http://our.api.com/Product?id=101404,7267261 Or is having JSON input handy? More of a pain? We may want to accept both styles but does that flexibility actually cause more confusion and head aches (maintainability, documentation, etc.)? A more complex case is when we want to offer more complex inputs. For example, if we want to allow multiple filters on search: http://our.api.com/Search?term=pumas&filters={"productType":["Clothing","Bags"],"color":["Black","Red"]} We don't necessarily want to put the filter types (e.g. productType and color) as request names like this: http://our.api.com/Search?term=pumas&productType=["Clothing","Bags"]&color=["Black","Red"] Because we wanted to group all filter input together. In the end, does this really matter? It may be likely that there are so many JSON utils out there that the input type just doesn't matter that much. I know our javascript clients making AJAX calls to the API may appreciate the JSON inputs to make their life easier. Thanks, Will

  • RESTful WCF Data Service Authentication

    - by Adrian Grigore
    Hi, I'd like to implement a REST api to an existing ASP.NET MVC website. I've managed to set up WCF Data services so that I can browse my data, but now the question is how to handle authentication. Right now the data service is secured via the site's built in forms authentication, and that's ok when accessing the service from AJAX forms. However, It's not ideal for a RESTful api. What I would like as an alternative to forms authentication is for the users to simply embed the user name and password into the url to the web service or as request parameters. For example, if my web service is usually accessible as http://localhost:1234/api.svc I'd like to be able to access it using the url http://localhost:1234/api.svc/{login}/{password} So, my questions are as follows: Is this a sane approach? If yes, how can I implement this? It seems trivial redirecting GET requests so that the login and password are attached as GET parameters. I also know how to inspect the http context and use those parameters to filter the results. But I am not sure if / how the same approach could be applied to POST, PUT and DELETE requests. Thanks, Adrian

  • Javascript :(….. Oh!! So its jquery? Now what?? I’m a C# Guy

    - by Shekhar_Pro
    Hi guys I want you to Guide me here. This other day I was working out some AJAX for my ASP.Net website and handling client side code in Java was taking the hell out of me. Then I got my hands on this Book jQuery In Action 2nd Edition and solved my problem with the help of Example code in the book. Now as I checked the contents I got an overview that whatever I had ever thought of doing can be done by this jQuery so easily and quite cleanly. I am actually pretty new to web development (say abt 4months ) and from C# world where we have cool libraries and Simple and Elegant coding style. (yeah including those generic, Ienumerable, lambadas, chained statements.. you got it…) and you know what you’re doing when writing some code. And we have so great IntelliSense to care., and above all we have everything Strongly Typed. But in Javascript everything is so messy.. . (and I don’t know why they are not properly indented.. see page source ) Now tell me what should I do, go straight with jQuery or should I first learn Javascript (like a disciplined boy…I even have a book for that too… got in gift :) …. ) I have seen Is it a good idea to learn JavaScript before learning jQuery? but remember I have already got a project on my hand…

  • Programmatically controlling a Dojo Accordion

    - by prule
    I have a dijit.layout.AccordionContainer on my page which is defined in the html and created when dojo parses the page on load. Then, as the user interacts with the page I use Ajax to retrieve data and programmatically populate the container (removing existing items first). To illustrate my issue simply, here is some code that doesn't work: function doit() { var accordion = dijit.byId("accordionShell"); accordion.getChildren().each(function(item) { accordion.removeChild(item); }); for (i = 1; i < 5; i++) { var d = new dijit.layout.AccordionPane({title:'hello', content:'world'}); accordion.addChild(d); } } This fails, because only the first item in the accordian is visible. I think the others actually exist, but they are not visible so you can't do anything. I've managed to get around it by: Always ensuring there is 1 item in the accordian (so I never remove the first child) Call accordian.layout() after changing the contents So, this code "works" as long as you always want to see the first item, and don't actually expand any but the first one: function doit() { var accordion = dijit.byId("accordionShell"); var i = 0; accordion.getChildren().each(function(item) { if (i > 0) accordion.removeChild(item); i++; }); for (i = 1; i < 5; i++) { var d = new dijit.layout.AccordionPane({title:'hello', content:'world'}); accordion.addChild(d); } accordion.layout(); } I am using Dojo 1.2.0 - Anyone know what I am doing wrong?

  • Looping through python-dictionary-turned-into-json in javascript.

    - by Phil
    In writing a django app, I am returning the following json on a jQuery ajax call: { "is_owner": "T", "author": "me", "overall": "the surfing lifestyle", "score": "1", "meanings": { "0": "something", "1": "something else", "3": "yet something else", "23": "something random" }, "user vote": "1" } In the javascript/jQuery callback function, I can access the is_owner, author, etc. easily enough. is_owner = json.is_owner; author = json.author; But for meanings, the numbers are different depending on what it pulls from the server. On the server side for the meanings part, right now what I'm doing is constructing a dictionary like so: meanings_dict = {} meanings = requested_tayke.meanings.all() for meaning in meanings: meanings_dict[meaning.location] = meaning.text and then returning a json I create like this: test_json = simplejson.dumps({'is_owner':is_owner, 'overall':overall, 'score':str(score),'user vote':str(user_vote), 'author': author, 'meanings' : meanings_dict }) print test_json return HttpResponse(test_json) My question is this: how do I access the 'meanings' data from my json in javascript? I need to loop through all of it. Maybe I need to be loading it into json differently. I have full control so of both the server and client side so I'm willing to change either to make it work. Also worth noting: I'm not using Django's serialize functionality. I couldn't make it work with my situation.

  • Rails Autocompletion Issue - Rails 1.2.3 to 2.3.5

    - by Grant Sayer
    I have an issue with rails Autocompletion from some code that i've inherited from an old Rails 1.2.3 project that I'm porting to Rails 2.3.5. The issue revolves around javascript execution within the auto_complete helper :after_update_element. The scenario is: A user is presented with a popup form with a number of fields. In the first field as they enter text the auto_complete AJAX call occurs, returning a result, plus a series of other HTML data wrapped in <divs> so that the after_update_element call can iterate over the other data and fill in the remaining fields. The issue lies with the extraction of the other fields which works on IE, fails on Firefox. Here is the code: <%= text_field_with_auto_complete :item, :product_code, {:value => ""}, {:size => 40, :class => "input-text", :tabindex => 6, :select => 'code', :with => "element.name + '=' + escape(element.value) + '&supplier_id=' + $('item_supplier_id').value", :after_update_element => "function (ele, value) { $('item_supplier_id').value = Utilities.extract_value(value, 'supplier_id'); $('item_supplied_size').value = Utilities.extract_value(value, 'size')}"}%> Now the function Utilities is designed to grab the fields from the string of values and looks like: // // Extract a particular set of data from the autocomplete actions // Utilities.extract_value = function (value, className) { var result; var elements = document.getElementsByClassName(className, value); if (elements && elements.length == 1) { result = elements[0].innerHTML.unescapeHTML(); } return result; }; In Firefox the value of result is undefined

  • Choosing a Java Web Framework now?

    - by hbagchi
    we are in the planning stage of migrating a large website which is built on a custom developed mvc framework to a java based web framework which provides built-in support for ajax, rich media content, mashup, templates based layout, validation, maximum html/java code separation. Grails looked like a good choice, however, we do not want to use a scripting language. We want to continue using java. Template based layout is a primary concern as we intend to use this web application with multiple web sites with similar functionality but radically different look and feel. Is portal based solution a good fit to this problem? Any insights on using "Spring Roo" or "Play" will be very helpful. I did find similar posts like this, but it is more than a year old. Things have surely changed in the mean time! EDIT 1: Thanks for the great answers! This site is turning to be the best single source for in-the-trenches programmer info. However, I was expecting more info on using a portal-cms duo. Jahia looks goods. Anything similar?

  • How to know $(window).load(); status from jquery

    - by Starx
    I have created a website loading bar using Jquery UI Progress bar, this progress bar shows the status of scripts loading. A sample is $.getScript('_int/ajax.js',function() { $("#progressinfo").html("Loading Complete ..."); $("#progressbar").progressbar({ value: 100 }); }); This progress bar is in #indexloader which is blocking the website being loaded behind, its CSS is #indexloader { z-index:100; position:fixed; top:0; left:0; background:#FFF; width:100%;height:100%; } After the progress bar reaches 100% I want to hide and remove #indexloader for that I used $("#indexloader").fadeOut("slow",function() { $("#indexloader").remove(); }); But the problem is, although the scripts have loaded, the pages are not fully loaded, I see images and other things still loading. So before fading and removing the #indexloader i want to check whether the $(window).load() has completed or not Is there a way to check this? Thanks in advance

  • Rotate a feature Image in Open Layers - ReApply StyleMap to layer.

    - by Ozaki
    I have an open layers map. It adds and removes my "imageFeature" every 10secs or so. I have a JSON feed that gives me the rotation that I need, I have a request to get that rotation and set it as a variable of rotationv. Everything works but the fact when the image is recreated it does not update the rotation. My code is as follows: JSON request: var rotationv = (function () { rotationv = null; $.ajax({ 'async': false, 'global': true, 'url': urldefault, 'dataType': "json", 'success': function (data) { rotationv = data.rotation; } }); return rotationv })(); Creating image feature: imageFeature = new OpenLayers.Feature.Vector( new OpenLayers.Geometry.Point(mylon, mylat), { rotation: rotationv } ); The image is set in the styling elsewhere. Why does this not rotate my image? Debugging with firebug I now notice that "rotationv" is updating as per it should be. But when the point is destroyed then added again it does not apply the new rotation... Add: I realised that the "image" is applied as per the layer. So I need to figure out how to re apply the stylemap to the layer so it will trigger the "update" on the page. //redefine layer 2 so it can be updated - test.js is just a 0.0 ref// var layer2 = new OpenLayers.Layer.GML("Layer 2", "test.js", { format: OpenLayers.Format.GeoJSON, styleMap: styleMap }); But even if I add the above into my function still no luck. Included map.addLayers([layer2]); into the function as well. Edit: Attaching stylemap: var styleMap = new OpenLayers.StyleMap({ "default": new OpenLayers.Style({ rotation: rotationv, labelXOffset: "0", labelYOffset: "-15", graphicZIndex: 1 }) });

  • Is jQuery.parseJSON able to process all valid json?

    - by murze
    This piece of valid json (it has been generated using php's json_encode): {"html":"form is NOT valid<form id=\"articleform\" enctype=\"application\/x-www-form-urlencoded\" method=\"post\" action=\"\"><dl class=\"zend_form\">\n<dt id=\"title-label\">&nbsp;<\/dt>\n<dd id=\"title-element\">\n<input type=\"text\" name=\"title\" id=\"title\" value=\"Artikel K\"><\/dd>\n<dt id=\"articleFormSubmitted-label\">&nbsp;<\/dt>\n<dd id=\"articleFormSubmitted-element\">\n<input type=\"hidden\" name=\"articleFormSubmitted\" value=\"1\" id=\"articleFormSubmitted\"><\/dd>\n<dt id=\"submit-label\">&nbsp;<\/dt><dd id=\"submit-element\">\n<input type=\"submit\" name=\"submit\" id=\"submit\" value=\"Bewaar artikel\" onclick=\"this.value='Bezig...';\"><\/dd><\/dl><\/form><script type=\"text\/javascript\">\n\t $(\"#articleform\").submit(function(){\n $.post(\"\/admin\/ajax\/contenttree\/node\/9\/ajaxtarget\/ajaxContainer\", $(\"#articleform\").serialize(), function(html){$(\"#ajaxContainer\").html(html);} );\n\t\t return false;\n\t });\n\n <\/script>","newNodeName":""} is giving jQuery.parseJSON(data) and me a hard time. With this piece of code: alert('start'); alert(data); jQuery.parseJSON(data) alert('stop'); I get a message start and then the data (jsonstring above) is shown. The message "stop" never appears. When I use this json: {"html":"test","newNodeName":""} I've verified that my first big chick of json is valid. Why isn't it processed by jQuery.parseJSON Are there any special characters that don't go well with json?

  • Will JSON replace XML as a data format?

    - by 13ren
    When I first saw XML, I thought it was basically a representation of trees. Then I thought: the important thing isn't that it's a particularly good representation of trees, but that it is one that everyone agrees on. Just like ASCII. And once established, it's hard to displace due to network effects. The new alternative would have to be much better (maybe 10 times better) to displace it. Of course, ASCII has been (mostly) replaced by Unicode, for internationalization. According to google trends, XML has a x43 lead, but is declining - while JSON grows. Will JSON replace XML as a data format? (edited) for which tasks? for which programmers/industries? NOTES: S-expressions (from lisp) are another representation of trees, but which has not gained mainstream adoption. There are many, many other proposals, such as YAML and Protocol Buffers (for binary formats). I can see JSON dominating the space of communicating with client-side AJAX (AJAJ?), and this possibly could back-spread into other systems transitively. XML, being based on SGML, is better than JSON as a document format. I'm interested in XML as a data format. XML has an established ecosystem that JSON lacks, especially ways of defining formats (XML Schema) and transforming them (XSLT). XML also has many other standards, esp for web services - but their weight and complexity can arguably count against XML, and make people want a fresh start (similar to "web services" beginning as a fresh start over CORBA).

  • .net MVC RenderPartial renders information that is not in the model

    - by Andreas
    Hi, I have a usercontrol that is rendering a list of items. Each row contains a unique id in a hidden field, a text and a delete button. When clicking on the delete button I use jquery ajax to call the controller method DeleteCA (seen below). DeleteCA returns a new list of items that replaces the old list. [HttpPost] public PartialViewResult DeleteCA(CAsViewModel CAs, Guid CAIdToDelete) { int indexToRemove = CAs.CAList.IndexOf(CAs.CAList.Single(m => m.Id == CAIdToDelete)); CAs.CAList.RemoveAt(indexToRemove); return PartialView("EditorTemplates/CAs", CAs); } I have checked that DeleteCA is really removing the correct item. The modified list of CAs passed to PartialView no longer contains the deleted item. Something weird happens when the partial view is rendered. The number of items in the list is reduced but it is always the last element that is removed from the list. The rendered items does not correspond to the items in the list/model sent to PartialView. In the usercontrol file (ascx) I'm using both Model.CAList and lambda expression m = m.CAList. How is it possible for the usercontrol to render stuff that is not in the model sent to PartialView? Thanx Andreas

  • Why doesn't jquery .load() load a text file from an external website?

    - by Edward Tanguay
    In the example below, when I click the button, it says "Load was performed" but no text is shown. I have a clientaccesspolicy.xml in the root directory and am able to asynchronously load the same file from silverlight. So I would think I should be able to access from AJAX as well. What do I have to change so that the text of the file http://www.tanguay.info/knowsite/data.txt is properly displayed in the #content element? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("jquery", "1.3.2"); google.setOnLoadCallback(function() { $('#loadButton').click(loadDataFromExernalWebsite); }); function loadDataFromExernalWebsite() { $('#content').load('http://www.tanguay.info/knowsite/data.txt', function() { alert('Load was performed.'); }); } </script> </head> <body> <p>Click the button to load content:</p> <p id="content"></p> <input id="loadButton" type="button" value="load content"/> </body> </html>

  • Running job in the background from Perl WITHOUT waiting for return

    - by Rafael Almeida
    The Disclaimer First of all, I know this question (or close variations) have been asked a thousand times. I really spent a few hours looking in the obvious and the not-so-obvious places, but there may be something small I'm missing. The Context Let me define the problem more clearly: I'm writing a newsletter app in which I want the actual sending process to be async. As in, user clicks "send", request returns immediately and then they can check the progress in a specific page (via AJAX, for example). It's written in your traditional LAMP stack. In the particular host I'm using, PHP's exec() and system() are disabled for security reasons, but Perl's system functions (exec, system and backticks) aren't. So my workaround solution was to create a "trigger" script in Perl that calls the actual sender via the PHP CLI, and redirects to the progress page. Where I'm Stuck The very line the calls the sender is, as of now: system("php -q sender.php &"); Problem being, it's not returning immediately, but waiting for the script to finish. I want it to run in the background but the system call itself returns right away. I also tried running a similar script in my Linux terminal, and in fact the prompt doesn't show until after the script has finished, even though my test output doesn't run, indicating it's really running in the background. What I already tried Perl's exec() function - same result of system(). Changing the command to: "php -q sender.php | at now"), hoping that the "at" daemon would return and that the PHP process itself wouldn't be attached to Perl. What should I try now?

  • accessing $_SESSION when using file_get_contents in PHP

    - by hairdresser-101
    I have a page called send.email.php which sends an email - pretty simple stuff - I pass an order id, it creates job request and sends it out. This works fine when used in the context I developed it (Use javascript to make an AJAX call to the URL and pass the order_id as a query parameter) I am now trying to reuse the exact same page in another application however I am calling it using php file_get_contents($base_url.'admin/send.email.php?order_id='.$order_id). When I call the page this way, the $_SESSION array is empty isempty() = 1. Is this because I am initiating a new session using file_get_contents and the values I stored in the $_SESSION on login are not available to me within there? -- Thanks for the feedback. It makes sense that the new call doesn't have access to the existing session... New problem though: I now get: failed to open stream: HTTP request failed! When trying to execute: $opts = array('http' => array('header'=> 'Cookie: ' . $_SERVER['HTTP_COOKIE']."\r\n")); $context = stream_context_create($opts); $contents = file_get_contents($base_url.'admin/send.sms.php?order_id='.order_id, false, $context); YET, the URL works fine if I call it as: (It just doesn't let me access session) $result file_get_contents($base_url.'admin/send.sms.php?order_id='.$order_id);

  • Spell checker software

    - by Naren
    Hello Guys, I have been assigned a task to find a decent spell checker (UK English) preferably the free one for a project that we are doing. I have looked at Google AJAX API for this. The project contains some young person's (kids less than 18 years old) data which shouldn't allow exposing or storing outside the application boundaries. Google logs the data for research purpose that means Google owns the data whatever we send over the wire through Google API. Is this right? I fired an email to Google regarding the privacy of data and storage but they haven't come back. If you have some knowledge regarding this please share with me. At this point our servers might not have access to external entities that means we might not be able to use Web API for this over the wire. But it may change in the future. That means I have to find out some spell checker alternatives that can sit in our environment and do the job or an external APIs. Would you mind share your findings and knowledge in this regard. I would prefer free services but never know if you have some cracking spell checker for a few quid’s then I don't mind recommending to the project board. Technology using ASP.NET 3.5/4.0, MVC, jQuery, SQL Sever 2008 etc Cheers, Naren

  • Overlay an HTML page with an HTML form

    - by jah
    Hi folks, this is a question about the best way (or least effort of the best ways) to overlay an html page with a form. Best in this context meaning best user experience whilst meeting the functional requirements. Let's say I have a page with a short form on it; the user has to enter some financial details. To assist the user to enter an accurate value for one of the fields there's another, much longer form. The longer form needs to be displayed only if the user requests the help. For users without javascript, clicking a link will submit the short form (persisting already filled fields in a session) and the server will respond with the long form. They'll submit the long form and the server will combine the submitted data with the persisted data and serve the short form again - with the fields populated. For users with javascript I want to overlay the short form page (in a lightbox stylee) with the long form, allow them to populate the long form and then go back to the short form with less round-trips to the server. Do I: Overlay the short form page with an iframe whose target is the long form? Request the long form over ajax and stuff it into a div? Generate the long form entirely on the client-side? Some other wizadry I haven't thought of? A short explanation of the best mechanism will do me very nicely indeed. Thank you very much!

  • How to determine the (natural) language of a document?

    - by Robert Petermeier
    I have a set of documents in two languages: English and German. There is no usable meta information about these documents, a program can look at the content only. Based on that, the program has to decide which of the two languages the document is written in. Is there any "standard" algorithm for this problem that can be implemented in a few hours' time? Or alternatively, a free .NET library or toolkit that can do this? I know about LingPipe, but it is Java Not free for "semi-commercial" usage This problem seems to be surprisingly hard. I checked out the Google AJAX Language API (which I found by searching this site first), but it was ridiculously bad. For six web pages in German to which I pointed it only one guess was correct. The other guesses were Swedish, English, Danish and French... A simple approach I came up with is to use a list of stop words. My app already uses such a list for German documents in order to analyze them with Lucene.Net. If my app scans the documents for occurrences of stop words from either language the one with more occurrences would win. A very naive approach, to be sure, but it might be good enough. Unfortunately I don't have the time to become an expert at natural-language processing, although it is an intriguing topic.

  • jQuery: script remember values between times it is triggered?

    - by Marius
    Hello there, I am writing an ajax script in jQuery. The script gets new or previous page from a php documents that returns HTML. If, located on page 1, I click next, the script IS able to find the next page number (page2), but when I click it AGAIN, the script again has to be able to find the next page number (page3) and at the minute it doesnt. I was wondering how I can save a variable between time a script is triggered, so that I can just + 1 to each time somebody clicks "next", and -1 when somebody clicks "previous". This is my code: $('.buttonNeste').click(function(event){ event.preventDefault(); if (page == null || id == null ) { var page = parseInt($(this).closest('.paginationFullWidth').attr('id')) + 1; var id = $(this).closest('.paginationFullWidth').siblings('.jtextfill').children('h1').attr('id'); } else { var page = page + 1; } var target = $(this); $.post( 'http://www.example.com/controllers/foo.php', { 'page': ( page ), 'id': id }, function(data) { $(target).closest('.paginationFullWidth').siblings('.commentsContainer').html(data); }); }); Thank you for your time. Kind regards, Marius

  • jqModal/JQuery problem, div not updating with new content?

    - by echoesofspring
    I'm hoping someone can point a relative jQuery/jqModal newbie in the right direction for debugging this error. I'm loading an html fragment into a div and then use jqModal to display that div as a modal dialog. The problem is that the div is displayed but not with my updated html. I'm showing my jqModal dialog in the response from a jquery call, function foo is called from an onclick event: function foo(url) { $.ajax({ type: "GET", url: url, success: function(msg) { $('#ajaxmodal').html(msg); $('#ajaxmodal').jqmShow(); } }); } ajaxmodal is a simple div. Initially I thought the problem must be in the html snippet (msg) I'm passing to the callback, but I don't think that's it, I get the err (see below) even when I comment out the $('#ajaxmodal').html(msg) line or pass it hardcode html. I think I have jqModal configured correctly, other calls using our ajaxmodal div work correctly, I'm able to display the modal, update the content based the server response, etc. When I try to debug in firebug, I get the following error following the call to .jqmShow(). I have seen the err on occasion in other places when it seemed maybe the page hadn't loaded yet, and I confess I'm confused about that, since we've wrapped our jqModal selectors in a $(document).ready() call, so maybe I have a larger issue that this call just happens to trigger? From the jquery.jqModal.js file, line 64: js err is $(':input:visible',h.w)[0] is undefined in the line: f=function(h){try{$(':input:visible',h.w)[0].focus();}catch(_){}} When I step through this in firefox, h.w[0] seems ok, it references our '#ajaxmodal' div. Thanks in advance for any suggestions in tracking this down?

  • Populating JavaScript Array from JSP List

    - by tkeE2036
    Ok so perhaps someone can help me with a problem I'm trying to solve. Essentially I have a JSP page which gets a list of Country objects (from the method referenceData() from a Spring Portlet SimpleFormController, not entirely relevant but just mentioning in case it is). Each Country object has a Set of province objects and each province and country have a name field: public class Country { private String name; private Set<Province> provinces; //Getters and setters } public class Province { private String name; //Getters and setters } Now I have two drop down menus in my JSP for countries and provinces and I want to filter the provinces by country. I've been following this tutorial/guide to make a chain select in JavaScript. Now I need a dynamic way to create the JavaScript array from my content. And before anyone mentions AJAX this is out of the question since our project uses portlets and we'd like to stay away from using frameworks like DWR or creating a servlet. Here is the JavaScript/JSP I have so far but it is not populating the Array with anything: var countries = new Array(); <c:forEach items="${countryList}" var="country" varStatus="status"> countries[status.index] = new Array(); countries[status.index]['country'] = ${country.name}; countries[status.index]['provinces'] = [ <c:forEach items="${country.provinces}" var="province" varStatus="provinceStatus"> '${province.name}' <c:if test="${!provinceStatus.last}"> , </c:if> </c:forEach> ]; </c:forEach> Does anyone know how to create an JavaScript array in JSP in the case above or what the 'best-practice' would be considered in this case? Thanks in advance!

  • javascript class calling XMLHttpRequest internally, then handling onreadystatechange

    - by Radu M
    this thing almost works: function myClass(url) { this.source = url; this.rq = null; this.someOtherProperty = "hello"; // open connection to the ajax server this.start = function() { if (window.XMLHttpRequest) { this.rq = new XMLHttpRequest(); if (this.rq.overrideMimeType) this.rq.overrideMimeType("text/xml"); } else this.rq = new ActiveXObject("Microsoft.XMLHTTP"); try { this.rq.onreadystatechange = connectionEvent; this.rq.open("GET", this.source, true); this.rq.send(null); this.state = 1; } catch (err) { // some error handler here } } function connectionEvent() { alert("i'm here"); alert("this doesnt work: " + this.someOtherProperty); } } // myClass so it's nothing more than having the XMLHttpRequest object as a member of my class, instead of globally defined, and invoking it in the traditional way. however, inside my connectionEvent callback function, the meaning of "this" is lost, even though the function itself is scoped inside myClass. i also made sure that the object that i instantiate from myClass is kept alive long enough (declared global in the script). in all the examples of using javascript classes that i saw, "this" was still available inside the inner functions. for me, it is not, even if i take my function outside and make it a myClass.prototype.connectionEvent. what am i doing wrong? thank you.

  • how to create wizard forms in ruby on rails

    - by Branden Silva
    I'm trying to understand the best options for pulling off a wizard form in ruby on rails. Ideally I'd like to have it so the application signup has a back and next button that allows the user to submit data in steps. So in step 1 they could fill out contact info. Once they are done they could click next and be on step 2 to fill out payment info, etc. If they make a mistake, they can click back and correct it. Some steps will be required, while others will not, but you do have to make it to the last step to submit the data to the database to sign up. They then need the ability to go back and fill out the past steps in the same fashion after completion. (example: perhaps if they clicked on a profile link they could recomplete the steps in the same fashion because they didn't want to complete all the steps right away. Maybe by being given a skip button before they completed the steps to sign up?). I also need validation to happen on what steps have been completed preventing them from moving onto the next step until corrected or completed. Option 1) I've noticed that ajax has been recommended as an option in other questions on stackoverflow. The only problem I have with it is that the user would not be able to sign up if javascript was disabled. Ideally I'd like to have it be native to ruby on rails but I'm willing to work with whatever is necessary to get it to work.
