  • Jquery mobile function calls before Ajax Request end

    - by rpmlins
    Here is my problem. When My Home page shows, I call the LoadUser functions, which on success, sets the globalUser variable with the returned json, and after it loads I call the alert function but it says globalUser is undefined. I have tried many other work arounds, but I always get the undefined mesage. If I call the alert(globalUser); on the success function, it works as expected alerting the object. $('#Home').live('pageshow', function(event) { $.when(LoadUser()).done(function(a1) { alert(globalUser); }); }); function LoadUser() { $.ajax({ // connects with the web service and validate de user input url: "http://localhost:51396/Icademy.asmx/GetUser", contentType: "application/json; charset=utf-8", data: { "userName": "'rodrigo'" }, dataType: "jsonp", success: function(json) { globalUser = JSON.parse(json.d); return globalUser; }, error: function(ret) { alert("Um erro ocorreu, tente novamente mais tarde."); } }); }

  • Is there more than one jQuery Autocomplete widget?

    - by Cheeso
    I thought there was only one - included in jQuery UI and documented here. I know there are third-party autocomplete widgets that plug-in to jQuery, like the one from devbridge. But I would describe that as an autocomplete widget for jQuery, rather than the jQuery autocomplete widget. But on Stackoverflow, I see questions asking about an autocomplete widget that does not use the syntax described in the jQuery UI documentation. For example: jquery.autocomplete.js - how does autocomplete work? Jquery AutoComplete Plugin calling Help with jquery autocomplete and json response The jQuery UI syntax looks like this: $("#input1").autocomplete({ source: function(req, responseFn) { ... }, select: function(value, data){ ... } }); Whereas some of those other questions hae a syntax like this: $("#city").autocomplete("CUList.asmx/GetCUList", { dataType: 'jsonp', parse: function(data) { var rows = new Array(); for(var i=0; i<data.length; i++){ rows[i] = { data:data[i], value:data[i].CUName, result:data[i].CUName }; } return rows; }, formatItem: function(row, i, n) { return row.CUName + ', ' + row.CUCity; }, max: 50 }); What's the explanation for the discrepancy? People ask about "jquery autocomplete" without specifying which one. With no direction, shouldn't I assume THE jquery UI autocomplete?

  • JQuery UI Autocomplete Syntax

    - by djs22
    Can someone help me understand the following code? I found it here. It takes advantage of the JQuery UI Autocomplete with a remote source. I've commented the code as best I can and a more precise question follows it. $( "#city" ).autocomplete({ source: function( request, response ) { //request is an objet which contains the user input so far // response is a callback expecting an argument with the values to autocomplete with $.ajax({ url: "http://ws.geonames.org/searchJSON", //where is script located dataType: "jsonp", //type of data we send the script data: { //what data do we send the script featureClass: "P", style: "full", maxRows: 12, name_startsWith: request.term }, success: function( data ) { //CONFUSED! response( $.map( data.geonames, function( item ) { return { label: item.name+(item.adminName1 ? ","+item.adminName1:"")+","+item.countryName, value: item.name } } ) ); } }); } }); As you can see, I don't understand the use of the success function and the response callback. I know the success function literal is an AJAX option which is called when the AJAX query returns. In this case, it seems to encapsulate a call to the response callback? Which is defined where? I thought by definition of a callback, it should be called on its own? Thanks!

  • How can I stop SharePoint from appending <mso:CustomDocumentProperties> to my output

    - by tath.am
    I'm trying to hack together an extra feature on top of a POC (smoke and mirrors demo). The POC is on SPS 2007 and I need to integrate with another system. To facilitate part of this, I need to provide a JSONP endpoint. I want this URL: http://sharepoint:2024/Pages/SomeExternalSystem/Payload.aspx?callback=abc To return this: abc({ sampleField1: "sampleData1", sampleField2: 234.56 }); It's all smoke and mirrors anyway, so I uploaded this file to SharePoint: <%@ Page ContentType="text/javascript" Language="C#" %> <%= Request.QueryString["callback"] %>({ sampleField1: "sampleData1", sampleField2: 234.56 }); (And added a page parser rule to allow it to compile the code blocks.) No matter what I seem to do, SharePoint emits this instead: abc({ sampleField1: "sampleData1", sampleField2: 234.56 }); <html xmlns:mso="urn:schemas-microsoft-com:office:office" xmlns:msdt="uuid:C2F41010-65B3-11d1-A29F-00AA00C14882"><head> <!--[if gte mso 9]><xml> <mso:CustomDocumentProperties> <mso:PublishingContactPicture msdt:dt="string"></mso:PublishingContactPicture> <mso:PublishingRollupImage msdt:dt="string"></mso:PublishingRollupImage> <mso:Audience msdt:dt="string"></mso:Audience> <mso:PublishingContactName msdt:dt="string"></mso:PublishingContactName> <mso:ContentType msdt:dt="string">Page</mso:ContentType> <mso:Comments msdt:dt="string"></mso:Comments> <mso:PublishingContactEmail msdt:dt="string"></mso:PublishingContactEmail> </mso:CustomDocumentProperties> </xml><![endif]--> </head> It's proving hard to Google for.

  • Problem with authentication from different domains using Django sessions.

    - by Greg
    Hi all, I am developing a bookmarklet which essentially adds a toolbar to a web page user is currently looking at. To use it, user needs to be logged in. To login user clicks on 'Singin' which displays a standard form containing Username, Password etc fields. When user successfully logs in they may chose to navigate to a different web-site. When on another page, they (a) re-load the bookmarklet (b) their session is retrieved from the server (c) user doesn't need to login again. Pretty standard I've would have thought. Using Django sessions and JQuery. I'm having troubles implementing the above usecase. Here are some problems I've encountered: Cross domain POST AJAX requests are disallowed. That was solved with JSONp. I doubt it is a very secure approach but for now it works. My server returns the session id in a cookie, however when the user navigates to a different page I don't really know how to retrieve that session id to send back to my server. Can I even read third party cookies from my JavaScript? I'm looking for some guidelines on implementing the above usecase. Ideally I don't want to redirect user to another page for them to sign in. Any suggestion would be greatly appreciated. Thanks.

  • jquery ui autocomplete with database

    - by user301766
    I fairly new to JQuery and perhaps trying to achieve something that might be abit harder for a beginner. However I am trying to create an autocomplete that sends the current value to a PHP script and then returns the necessary values. Here is my Javascript code $("#login_name").autocomplete({ source: function(request, response) { $.ajax({ url: "http://www.myhost.com/myscript.php", dataType: "jsonp", success: function(data) { alert(data); response($.map(data, function(item) { return { label: item.user_login_name, value: item.user_id } })) } }) }, minLength: 2 }); And here is the the last half of "myscript.php" while($row = $Database->fetch(MYSQLI_ASSOC)) { foreach($row as $column=>$val) { $results[$i][$column] = $val; } $i++; } print json_encode($results); Which produces the following output [{"user_id":"2","user_login_name":"Name1"},{"user_id":"3","user_login_name":"Name2"},{"user_id":"4","user_login_name":"Name3"},{"user_id":"5","user_login_name":"Name4"},{"user_id":"6","user_login_name":"Name5"},{"user_id":"7","user_login_name":"Name6"}] Can anyone tell me where I am going wrong please? Starting to get quite frustrated. The input box just turns "white" and no options are shown. The code does work if I specify an array of values.

  • jQuery1.4.2 $.ajax crashes IE6/7

    - by Kenny Eliasson
    Hello there! I'm having a really hard time debugging one of our latest reported bugs. The problem occurs "randomly", not on every page load, sometimes I can "click" around for a minute or two before IE6/7 crashes. By crash I mean that the IE-window shuts down and I get the option to send the crash info to Microsoft. In FF, Chrome, Safari, IE8 everything is working perfectly. What the page does is issuing 2 AJAX Jsonp calls and building some menus with the data returned. The data brought back can be from ~500b to approx. 35kb. The JSON is valid (else it wouldn't have loaded at all in FF etc), and as i told previous, it works for when navigating around the site soemtimes in IE6/7. I've tested to comment out the callbacks, still crashes. If I remove the $.ajax calls the page will work again. Whats strange is that if I downgrade to jQuery 1.3.2 everything works in all browsers including IE6/7. I've taken the crash-logs and looked at them in WinDbg and what happens seems to be a NULL POINTER reference. The last entries of the stack trace is as follows mshtml!CTreePos::SourceIndex+0x9 mshtml!CMarkup::InsertElementInternal+0x3a8 mshtml!CDoc::InsertElement+0x98 mshtml!CDocument::get_implementation+0x144 Anyone having a clue what could cause this?

  • WCF REST with jQuery AJAX - removing/working around same origin policy

    - by csauve
    So I'm trying to create a C# WCF REST service that is called by jQuery. I've discovered that jQuery requires that AJAX calls are made under the same origin policy. I have a few questions for how I might proceed. I am already aware of; 1. The hacky solution of JSONP with a server callback 2. The way too much server overhead of having a cross-domain proxy. 3. Using Flash in the browser to make the call and setting up crossdomain.xml at my WCF server root. I'd rather not use these because; 1. I don't want to use JSON, or at least I don't want to be restricted to using it 2. I would like to separate the server that serves static pages from the one that serves application state. 3. Flash in this day in age is out of the question. What I'm thinking: is there anything like Flash's crossdomain.xml file that works for jQuery? Is this "same-origin" policy a part of jQuery or is it a restriction in specific browsers? If it's just a part of jQuery, maybe I'll try digging in the code to work around it.

  • jQuery: Inserting li items one by one?

    - by Legend
    I wrote the following (part of a jQuery plugin) to insert a set of items from a JSON object into a <ul> element. ... query: function() { ... $.ajax({ url: fetchURL, type: 'GET', dataType: 'jsonp', timeout: 5000, error: function() { self.html("Network Error"); }, success: function(json) { //Process JSON $.each(json.results, function(i, item) { $("<li></li>") .html(mHTML) .attr('id', "div_li"+i) .attr('class', "divliclass") .prependTo("#" + "div_ul"); $(slotname + "div_li" + i).hide(); $(slotname + "div_li" + i).show("slow") } } }); } }); }, ... Doing this maybe adding the <li> items one by one theoretically but when I load the page, everything shows up instantaneously. Instead, is there an efficient way to make them appear one by one more slowly? I'll explain with a small example: If I have 3 items, this code is making all the 3 items appear instantaneously (at least to my eyes). I want something like 1 fades in, then 2 fades in, then 3 (something like a newsticker perhaps). Anyone has a suggestion?

  • jQuery HOW TO?? pass additional parameters to success callback for $.ajax call ?

    - by dotnetgeek
    Hello jQuery Ninjas! I am trying, in vain it seems, to be able to pass additional parameters back to the success callback method that I have created for a successful ajax call. A little background. I have a page with a number of dynamically created textbox / selectbox pairs. Each pair having a dynamically assigned unique name such as name="unique-pair-1_txt-url" and name="unique-pair-1_selectBox" then the second pair has the same but the prefix is different. In an effort to reuse code, I have crafted the callback to take the data and a reference to the selectbox. However when the callback is fired the reference to the selectbox comes back as 'undefined'. I read here that it should be doable. I have even tried taking advantage of the 'context' option but still nothing. Here is the script block that I am trying to use: <script type="text/javascript" language="javascript"> $j = jQuery.noConflict(); function getImages(urlValue, selectBox) { $j.ajax({ type: "GET", url: $j(urlValue).val(), dataType: "jsonp", context: selectBox, success:function(data){ loadImagesInSelect(data, $j(this)) } , error:function (xhr, ajaxOptions, thrownError) { alert(xhr.status); alert(thrownError); } }); } function loadImagesInSelect(data, selectBox) { //var select = $j('[name=single_input.<?cs var:op_unique_name ?>.selImageList]'); var select = selectBox; select.empty(); $j(data).each(function() { var theValue = $j(this)[0]["@value"]; var theId = $j(this)[0]["@name"]; select.append("<option value='" + theId + "'>" + theValue + "</option>"); }); select.children(":first").attr("selected", true); } From what I have read, I feel I am close but I just cant put my finger on the missing link. Please help in your typical ninja stealthy ways. TIA

  • Json HTTP Module stream issue

    - by Justin
    Hey, I have an HTTP Module that I use to clean up the JSON returned by my web service (see http://www.codeproject.com/KB/webservices/ASPNET_JSONP.aspx?msg=3400287#xx3400287xx for an example of this.) Basically it relates to calling cross-domain JSON web services from javascript. There is this JsonHttpModule which uses a JsonResponseFilter Stream class to write out the JSON and the overloaded Write method is supposed to wrap the name of the callback function around the JSON, otherwise the JSON errors out as needing a label. However, if the JSON is really long, the Write method in the Stream class is called multiple times, causing the callback function to incorrectly get inserted midway through the JSON. Is there a way in the Stream class to wrap the callback function around the stream at the end or to specify that it write all of the JSON in 1 Write method instead of in chunks?? Here's where it calls the JsonResponseFilter in the JsonHttpModule: public void OnReleaseRequestState(object sender, EventArgs e) { HttpApplication app = (HttpApplication)sender; if (!_Apply(app.Context.Request)) return; // apply response filter to conform to JSONP app.Context.Response.Filter = new JsonResponseFilter(app.Context.Response.Filter, app.Context); } Here's the Write method in the JsonResponseFilter Stream class that gets called multiple times: public override void Write(byte[] buffer, int offset, int count) { var b1 = Encoding.UTF8.GetBytes(_context.Request.Params["callback"] + "("); _responseStream.Write(b1, 0, b1.Length); _responseStream.Write(buffer, offset, count); var b2 = Encoding.UTF8.GetBytes(");"); _responseStream.Write(b2, 0, b2.Length); } Thanks for any help!

  • Cross-domain templating with Javascript

    - by Husky
    I'm currently building a Javascript library that can be used to easily create embeddable media based on the URL of a media file, and then be controlled using Javascript methods and events (think something like the Flash / Silverlight JW player). Of course, i could simply cat all the html tags from the Javascript library and send that to the browser: function player(url) { document.write('<object type="foo"><param name="something" value="bar">' + <param name="source" value=" + url + '/></object>'); } But i think this is a very ugly practice that tends to create unmanageable code that is unreadable when you review it a few weeks later. So, a templating solution seems to be the way to go. I've been looking to EJS because it loads the templates using AJAX, so you can manage your templates in separate file instead of directly on the HTML page. There's one 'gotcha' with that: my library needs to be completely cross-domain: the library itself could be located on foo.com while the serving site could be located on bar.com. So if bar.com would want to add a media player using the library it needs to do an AJAX call to a template located on foo.com, which won't work because of the same-origin policy in browsers. AFAIK, there's no library that uses something like JSONP to read and write templates to get around this problem. Could anyone point me to a solution for this problem?

  • How to output JSON from within Django and call it with jQuery from a cross domain?

    - by Emre Sevinç
    For a bookmarklet project I'm trying to get JSON data using jQuery from my server (which is naturally on a different domain) running a Django powered system. According to jQuery docs: "As of jQuery 1.2, you can load JSON data located on another domain if you specify a JSONP callback, which can be done like so: "myurl?callback=?". jQuery automatically replaces the ? with the correct method name to call, calling your specified callback." And for example I can test it successfully in my Firebug console using the following snippet: $.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any& format=json&jsoncallback=?", function(data){ alert(data.title); }); It prints the returned data in an alert window, e.g. 'Recent uploads tagged cat'. However when I try the similar code with my server I don't get anything at all: $.getJSON("http://mydjango.yafz.org/randomTest?jsoncallback=?", function(data){ alert(data.title); }); There are no alert windows and the Firebug status bar says "Transferring data from mydjango.yafz.org..." and keeps on waiting. On the server side I have this: def randomTest(request): somelist = ['title', 'This is a constant result'] encoded = json.dumps(somelist) response = HttpResponse(encoded, mimetype = "application/json") return response I also tried this without any success: def randomTest(request): if request.is_ajax() == True: req = {} req ['title'] = 'This is a constant result.' response = json.dumps(req) return HttpResponse(response, mimetype = "application/json") So to cut a long story short: what is the suggested method of returning a piece of data from within a Django view and retrieve it using jQuery in a cross domain fashion? What are my mistakes above?

  • How can I display an ASP.NET MVC html part from one application in another

    - by Frank Sessions
    We have several asp.net MVC apps in the following setup SecurityApp (root application - handles forms auth for SSO and has a profile edit page) Application1 (virtual directory) Application2 (virtual directory) Application3 (virtual directory) so that domain.com points to SecurityApp and domain.com/Application1 etc point to their associated virtual directories. All of our Single Sign On (SSO) is working properly using forms authentication. Based on the users permissions when logging in a menu that lists their available applications and a logout link will be generated and saved in the cache - this menu displays fine whenever the user is in the SecurityApp (editing their profile) but we cannot figure out how to get the Applications in the virtual directories to display the same application menu. We have tried: 1) Using JSONP to do an request that will return the html for the menu. The ajax call returns the HTML with the html; however, because User.IsAuthenticated is false the menu comes back empty. 2) We created a user control and include it along with the dll's for the SecurityApp project and this works; however, we dont want to have to include all the dlls for the SecurityApp project in every application that we create (along with all the app settings in the web.config) We would like this to be as simple as possible to implement so that anyone creating a new app can add the menu to their application in as few steps as possible... Any ideas? To Clarify - we are using ASP.NET MVC 1.0 since these apps are in production and we do not have the okay to go to ASP.NET MVC 2.0 (unfortunately)

  • RPC for java/python with rest support, HTML monitoring and goodies

    - by Ran
    Here's my set of requirements: I'm looking for an RPC framework such as thrift, avro, protobuf (when adding services to it) which supports: Easy and intuitive IDL. No serial numbers, no manual versioning, simple... avro is a good example for this. Works with Java and Python Supports both fast binary prorocol, as well as HTTP based restful style. I'd like to be able to use it for both backend-to-backend communication (java-java or python-java) as well as frontend-to-backend communication (javascript to java). The rest support needs to include &param=value input as get/post requests (configurable per request) and output in three possible formats: json, jsonp, XML. Compact, fast, backward compatible, easy to upgrade etc... Provides some nice monitoring interfaces such as: JMX, web page status reports (e.g. packets in, packets out, error rate etc) Ops friendly... no need to take the whole site down to release new versions Both sync and asyc communication ... other goodies are welcome... Is there something out there? So far I've looked at thrift and avro and they are both nice in some ways, but don't check all my list. Thanks

  • How do I fully reload my Sencha Touch App when tapping 'refresh'?

    - by torr
    My list view layout is similar to Pinterest, with absolutely positioned blocks. Unfortunately, this seems to require a full re-initialization at refresh. If reload only the store (as below) the new blocks are incorrectly positioned. How do I reload the app when the user clicks on refresh? This is my View: Ext.require(['Ext.data.Store', 'MyApp.model.StreamModel'], function() { Ext.define('MyApp.view.HomeView', { extend: 'Ext.navigation.View', xtype: 'homepanel', requires: [ 'Ext.dataview.List', ], config: { title: 'Home', iconCls: 'home', styleHtmlContent: true, navigationBar: { items: [ { xtype: 'button', iconMask: true, iconCls: 'refresh', align: 'left', action: 'refreshButton' } ] }, items: { title: 'My', xtype: 'list', itemTpl: [ '<div class="post">', ... '</div>' ].join(''), store: new Ext.data.Store({ model: 'MyApp.model.StreamModel', autoLoad: true, storeId: 'stream' }), } } }); }); Model: Ext.define('MyApp.model.StreamModel', { extend: 'Ext.data.Model', config: { fields: [ 'post_id', 'comments' ], proxy: { type: 'jsonp', url: 'http://My.com/app', reader: { type: 'json', } } } }); and my Controller: Ext.define('MyApp.controller.RefreshController', { extend: 'Ext.app.Controller', requires: [ 'Ext.navigation.View' ], config: { control: { 'button[action=refreshButton]': { tap: 'refresh' } } }, refresh: function() { // Ext.StoreMgr.get('stream').load(); // here I'd like to reload the app instead // not just the store } });

  • Cross-Origin Resource Sharing (CORS) - am I missing something here?

    - by David Semeria
    I was reading about CORS (https://developer.mozilla.org/en/HTTP_access_control) and I think the implementation is both simple and effective. However, unless I'm missing something, I think there's a big part missing from the spec. As I understand, it's the foreign site that decides, based on the origin of the request (and optionally including credentials), whether to allow access to its resources. This is fine. But what if malicious code on the page wants to POST a user's sensitive information to a foreign site? The foreign site is obviously going to authenticate the request. Hence, again if I'm not missing something, CORS actually makes it easier to steal sensitive information. I think it would have made much more sense if the original site could also supply an immutable list of servers its page is allowed to access. So the expanded sequence would be: 1) Supply a page with list of acceptable CORS servers (abc.com, xyz.com, etc) 2) Page wants to make an XHR request to abc.com - the browser allows this because it's in the allowed list and authentication proceeds as normal 3) Page wants to make an XHR request to malicious.com - request rejected locally (ie by the browser) because the server is not in the list. I know that malicious code could still use JSONP to do its dirty work, but I would have thought that a complete implementation of CORS would imply the closing of the script tag multi-site loophole. I also checked out the official CORS spec (http://www.w3.org/TR/cors) and could not find any mention of this issue.

  • select2: "text is undefined" when getting json using ajax

    - by user3046715
    I'm having an issue when getting json results back to select2. My json does not return a result that has a "text" field so need to format the result so that select2 accepts "Name". This code works if the text field in the json is set to "text" but in this case, I cannot change the formatting of the json result (code outside my control). $("#e1").select2({ formatNoMatches: function(term) {return term +" does not match any items." }, ajax: { // instead of writing the function to execute the request we use Select2's convenient helper url: "localhost:1111/Items.json", dataType: 'jsonp', cache: true, quietMillis: 200, data: function (term, page) { return { q: term, // search term p: page, s: 15 }; }, results: function (data, page) { // parse the results into the format expected by Select2. var numPages = Math.ceil(data.total / 15); return {results: data.Data, numPages: numPages}; } } }); I have looked into the documentation and found some statements you can put into the results such as text: 'Name', but I am still getting "text is undefined". Thanks for any help.

  • Apache Cordova (Phonegap): is jsop needed for cross-site scripting?

    - by DEX
    I've just started using Apache Cordova. I have an library that makes calls (via ajax) to a soap server. When I run these on my local machine in chrome, I get cross site scripting errors when trying to make calls to the service. When I run the same exact code using the Cordova browser in the iOS emulator, the scripts seem to hit the server fine and the response data is received properly. So my question is how is the Cordova browser able to make these requests without cross-site scripting permissions & JSONP ? One thing I noticed is that when the request is sent from iOS, there is no "Origin" header. Is this allowing the Cordova browser to stealthily circumvent cross-site scripting requirements? Is it possible that the node.js server on the device (I believe this is how Cordova works) is manipulating the headers to allow this? I'd like to avoid enabling cross-site scripting on my site so I think this "feature" is nice, but I'm wondering if it's a security hole as well. Anyone have experience with this?

  • No results are returned when using Flickr JSON request

    - by Martijn1981
    I'm still fairly new to AJAX and I'm experimenting with Twitter and Flickr. Twitter is working fine so far, but I've run into some issues with the Flickr API. I'm getting no results back. The URL seems to be working fine and I'm pointing to the right object containing the array ('items'). Can anybody tell me what I'm doing wrong please? Thanks! $('#show_pictures').click(function(e){ e.preventDefault(); $.ajax({ url: 'http://api.flickr.com/services/feeds/photos_public.gne?format=json&jsoncallback=?&tags=home', dataType: 'jsonp', success: function(data) { $.each(data.items, function(i, item){ $('<div></div>') .hide() .append('<h1>'+item.title+'</h1>') .append('<img src="'+item.media.m+'" >') .append('<p>'+item.description+'</p>') .appendTo('#results') .fadeIn(); }) }, error: function(data) { alert('Something went wrong!'); } }); });

  • jQuery .ajax method executing but not firing error (or success)

    - by John Swaringen
    I'm having a very strange situation. I have a .NET Web Service (.asmx) that I'm trying to call via jQuery ajax to populate some <select></select>'s. The service is running System.Web.Services like it's supposed to and should be returning a JSON list. At least that's the way I understand that it will in .NET 3.5/4.0. The main problem is that the .ajax() function (below) seems to execute but the internal callbacks aren't executing. I know it's executing because I can do something before and after the function and both execute, so JavaScript isn't blowing up. $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: 'http://localhost:59191/AFEDropDownService/Service.asmx/GetAVP', data: "{}", dataType: "jsonp", crossDomain: true, success: function(list) { console.log(list); console.log("success!!"); }, error: function(msg) { console.log("error: " + msg.text); } }); If you need more of the code let me know. Or if you know a better way as I'm trying to build cascading <select></select's.

  • OpenCalais API using jQuery

    - by Varun
    Hi I've wanted to do some language processing for an application and have been trying to use the OpenCalais API. The call to the API works perfectly and returns data. The problem is that even though I can see the data in the firebug, I cannot access it because the callback never triggers. Details: the call requires callback=? as it is a JSONP request. so callback=foo SHOULD call the foo method once the data is returned, it doesn't. in fact, if callback is anything other than ? the call fails and doesn't return any data. (i've also checked JSLint to make sure the returned JSON is valid). tried using $.ajax instead of $.getJSON so that I can get an error callback, but neither the success or error callbacks fire. in firebug, usually when you make a JSON request, the request shows up in the console. In this case, the request doesn't show up in the console, but instead shows in the "Net" tab in firebug...dunno what that means, but somehow the browser doesn't think its an XHR request. any ideas? thanks.
