• Client-side templating frameworks to streamline using jQuery with REST/JSON

  - by Tauren

  I'm starting to migrate some html generation tasks from a server-side framework to the client. I'm using jQuery on the client. My goal is to get JSON data via a REST api and use this data to populate HTML into the page. Right now, when a user on my site clicks a link to My Projects, the server generates HTML like this: <dl> <dt>Clean Toilet</dt> <dd>Get off your butt and clean this filth!</dd> <dt>Clean Car</dt> <dd>I think there's something growing in there...</dd> <dt>Replace Puked on Baby Sheets</dt> </dl> I'm changing this so that clicking My Projects will now do a GET request that returns something like this: [ { "name":"Clean Car", "description":"I think there's something growing in there..." }, { "name":"Clean Toilets", "description":"Get off your butt and clean this filth!" }, { "name":"Replace Puked on Baby Sheets" } ] I can certainly write custom jQuery code to take that JSON and generate the HTML from it. This is not my question, and I don't need advice on how to do that. What I'd like to do is completely separate the presentation and layout from the logic (jquery code). I don't want to be creating DL, DT, and DD elements via jQuery code. I'd rather use some sort of HTML templates that I can fill the data in to. These templates could simply be HTML snippets that are hidden in the page that the application was loaded from. Or they could be dynamically loaded from the server (to support user specific layouts, i18n, etc.). They could be displayed a single time, as well as allow looping and repeating. Perhaps it should support sub-templates, if/then/else, and so forth. I have LOTS of lists and content on my site that are presented in many different ways. I'm looking to create a simple and consistent way to generate and display content without creating custom jQuery code for every different feature on my site. To me, this means I need to find or build a small framework on top of jQuery (probably as a plugin) that meets these requirements. The only sort of framework that I've found that is anything like this is jTemplates. I don't know how good it is, as I haven't used it yet. At first glance, I'm not thrilled by it's template syntax. Anyone know of other frameworks or plugins that I should look into? Any blog posts or other resources out there that discuss doing this sort of thing? I just want to make sure that I've surveyed everything out there before building it myself. Thanks!

• 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.

• jQuery plugin validate() : apply plugin to ajax injected form

  - by pixelboy

  My issue here is quite simple : i'm trying to use the jQuery validate plugin to a form that gets injected after certain user actions. My problem mostly is that : I could use live support to bind the change event over inputs, like this $("#adresseLivraisonPro").live('change',function(e){ $("#adresseLivraisonPro").validate({ But this makes my form validated if and only if user changes inputs... How would you surround that problem ?

• Cannot populate form with ajax and populate jquery plugin

  - by Azriel_

  I'm trying to populate a form with jquery's populate plugin, but using $.ajax The idea is to retrieve data from my database according to the id in the links (ex of link: get_result_edit.php?id=34), reformulate it to json, return it to my page and fill up the form up with the populate plugin. But somehow i cannot get it to work. Any ideas: here's the code: $('a').click(function(){ $('#updatediv').hide('slow'); $.ajax({ type: "GET", url: "get_result_edit.php", success: function(data) { var $response=$(data); $('#form1').populate($response); } }); $('#updatediv').fadeIn('slow'); return false; whilst the php file states as follow: <?php $conn = new mysqli('localhost', 'XXXX', 'XXXXX', 'XXXXX'); @$query = 'Select * FROM news WHERE id ="'.$_GET['id'].'"'; $stmt = $conn->query($query) or die ($mysql->error()); if ($stmt) { $results = $stmt->fetch_object(); // get database data $json = json_encode($results); // convert to JSON format echo $json; } ?> Now first thing is that the mysql returns a null in this way: is there something wrong with he declaration of the sql statement in the $_GET part? Second is that even if i put a specific record to bring up, populate doesn't populate. Update: I changed the populate library with the one called "PHP jQuery helper functions" and the difference is that finally it says something. finally i get an error saying NO SUCH ELEMENT AS i wen into the library to have a look and up comes the following function function populateFormElement(form, name, value) { // check that the named element exists in the form var name = name; // handle non-php naming var element = form[name]; if(element == undefined) { debug('No such element as ' + name); return false; } // debug options if(options.debug) { _populate.elements.push(element); } } Now looking at it one can see that it should print out also the name, but its not printing it out. so i'm guessing that retrieving the name form the json is not working correctly. Link is at http://www.ocdmonline.org/michael/edit%5Fnews.php with username: Testing and pass:test123 Any ideas?

• jquery checkbox help

  - by sea_1987

  The Problem I am trying to run some ajax on one my pages for my website, basically I have three checkboxes all of which on pageload are unselected, when a checkbox is clicked I need to be able load in via ajax the relevant HTML. This system is currently a PHP script that depending on what the POST is set returns a different view, so I think all I need to is send the POST via AJAX, but I need to do everytime a new checkbox is checked. My HTML looks like this, div class="segment"> <div class="label"> <label>Choose region: </label> </div> <div class="column w190"> <div class="segment"> <div class="input"> <input type="checkbox" checked="checked" class="radio checked" value="Y" name="area[Nationwide]" id="inp_Nationwide"> </div> <div class="label "> <label for="inp_Nationwide">Nationwide</label> </div> <div class="s">&nbsp;</div> </div> </div> <div class="column w190"> <div class="segment"> <div class="input"> <input type="checkbox" checked="checked" class="radio checked" value="Y" name="area[Lancashire]" id="inp_Lancashire"> </div> <div class="label "> <label for="inp_Lancashire">Lancashire</label> </div> <div class="s">&nbsp;</div> </div> </div> <div class="column w190"> <div class="segment"> <div class="input"> <input type="checkbox" checked="checked" class="radio" value="Y" name="area[West_Yorkshire]" id="inp_West_Yorkshire"> </div> <div class="label "> <label for="inp_West_Yorkshire">West Yorkshire</label> </div> <div class="s">&nbsp;</div> </div> <div class="s">&nbsp;</div> </div> </div> My current attempt was to ascertain whether the input has been clicked so I have done this with my javascript, though this is probably wrong, $('input.radio').click(function(){ if($(this).hasClass('clicked')) { $(this).removeClass('clicked'); } else { $(this).addClass('clicked'); } });

• Thread-safe queue in Javascript or jQuery

  - by at

  I have many asynchronous AJAX calls whose results will get processed. It doesn't matter what order the processing occurs, but the results need to get processed one at a time. So I'd like to simple do my AJAX calls and they all just put their results in a single queue. That queue should then get processed on a single thread. This way the results get processed one at a time as soon as possible. What's the best way to do this? I'm using jQuery, so happy to take advantage of any facilities it provides for this.

• jQuery show submit button on input field click

  - by Pjack

  Hi, I'm trying to have a comment input field that will show the submit button on a dynamically created form when you click on the input field. Similar to how facebook comments work. When you click on the input field the submit button appears and when you click off it disappears. All the comment input id's are comment_1 etc and the submit button id's are submit_1 etc. I've tried this, jQuery("#[id^='comment_']").live('click',function(event){ if(jQuery("#[id^='comment_']").val() == ""){ jQuery("#[id^='submit_']").hide(); } else { jQuery("#[id^='submit_']").show(); } }); And that won't work for some reason. Any suggestion or how it can be accomplished would be great.

• IE browser caching and the jQuery Form Plugin

  - by Harfleur

  Like so many lost souls before me, I'm floundering in the snake pit that is Ajax form submission and IE browser caching. I'm trying to write a simple script using the jQuery Form Plugin to Ajaxify Wordpress comments. It's working fine in Firefox, Chrome, Safari, et. al., but in IE, the response text is cached with the result that Ajax is pulling in the wrong comment. jQuery(this).ajaxSubmit({ success: function(data) { var response = $("<ol>"+data+"</ol>"); response.find('.commentlist li:last').hide().appendTo(jQuery('.commentlist')).slideDown('slow'); } }); ajaxSubmit sends the comment to wp-comments-post.php, which inelegantly spits back the entire page as a response. So, despite the fact that it's ugly as toads, I'm sticking the response text in a variable, using :last to isolate the most recent comment, and sliding it down in its place. IE, however, is returning the cached version of the page, which doesn't include the new comment. So ".commentlist li:last" selects the previous comment, a duplicate of which then uselessly slides down beneath the original. I've tried setting "cache: false" in the ajaxSubmit options, but it has no effect. I've tried setting a url option and tacking on a random number or timestamp, but it winds up being attached to the POST that submits the comment to the server rather than the GET that returns the response, and so has no effect. I'm not sure what else to try. Everything works fine in IE if I turn off browser caching, but that's obviously not something I can expect anyone viewing the page to do. Any help will be hugely appreciated. Thanks in advance! EDIT WITH A PROGRESS REPORT: A couple of people have suggested using PHP headers to prevent caching, and this does indeed work. The trouble is that wp-comments-post is spitting back the entire page when a new comment is submitted, and the only way I can see to add headers is to put them in the Wordpress post template, which disables caching on all posts at all times--not quite the behavior I'm looking for. Is there a way to set a php conditional--"if is_ajax" or something like that--that would keep the headers from being applied during regular pageloads, but plug them in if the page was called by an Ajax GET?

• Get reference to all instances of jquery ui widget?

  - by Hailwood

  I am writing a jquery UI widget that simply wraps the bootstrap popover plugin, In the widget you can pass in the option 'singular', if this is passed in then it should call a function of all other instances of the plugin. something like $('#one').myWidget(); $('#two').myWidget(); $('#three').myWidget(); $('#four').myWidget(); $('#one').myWidget('show'); //stuff from widget one is now visible $('#two').myWidget('show'); //stuff from widget one and two are now visible $('#three').myWidget('show'); //stuff from widget one, two and three are now visible $('#two').myWidget('hide'); //stuff from widget one and three are now visible $('#four').myWidget('show', {singular:true}); //stuff from widget four is now visible So, I imagine the show function looking like: show: function(options){ options = options || {}; if(options.singular){ var instances = '????'; // how do I get all instances? $.each(instances, function(i, o){ o.myWidget('hide'); }); } this.element.popover('show'); } So, question being, how would I get a reference to all elements that have the myWidget widget on them?

• Update JQuery Progressbar with JSON Response in an ajax Request

  - by Vincent

  All, I have an AJAX request, which makes a JSON request to a server, to get the sync status. The JSON Request and responses are as under: I want to display a JQuery UI progressbar and update the progressbar status, as per the percentage returned in the getStatus JSON response. If the status is "insync", then the progressbar should not appear and a message should be displayed instead. Ex: "Server is in Sync". How can I do this? //JSON Request to getStatus { "header": { "type": "request" }, "payload": [ { "data": null, "header": { "action": "load", } } ] } //JSON Response of getStatus (When status not 100%) { "header": { "type": "response", "result": 400 }, "payload": [ { "header": { "result": 400 }, "data": { "status": "pending", "percent": 20 } } ] } //JSON Response of getStatus (When percent is 100%) { "header": { "type": "response", "result": 400 }, "payload": [ { "header": { "result": 400 }, "data": { "status": "insync" } } ] }

• jQuery-Ui Ajax Tabs bug?

  - by vsync

  I have a JSON that returns from the server which tabs to build, so I init them in my JS like this: $('#tabs').tabs( 'ajaxOptions', { timeout: 20000, error: function(xhr, status, index, anchor){ console.log( status, index, anchor ); } }) .tabs('add', item.CategoryLink, item.CategoryName); Thing is, when I click a tab, and before it is done loading I click another tab, the previous request is aborted and never called again when I click that first one again! this is very bad, because it obviously didn't fetch the request, so what gives? I tried bypassing this by setting: .tabs({ cache: false }) but this is a bad thing to do, because I don't want to have a request each time again... it should be cachced if response was sent. using jquery-ui 1.8.1

• Returning mySQL error with jQuery & AJAX

  I've got a form inserting data into mySQL. It works but I'm trying to add error handling in case something happens.

• jQuery Address Plugin - Not allowing loading ajax?

  - by Nic Hubbard

  I am trying to test the jQuery Address Plugin and it seems to not allow ajax to work in the change function. I am using: $.address.change(function(event) { $('#content').load(event.value+' #content'); $.address.title(event.value); }); $('a').click(function() { $.address.value($(this).attr('href')); }); While I can use event.value for other things, it just does not seem to let the .load() function work. Even trying a static URL in .load() does nothing. Is something in the plugin preventing this? I thought this was the point of the plugin!

• DevConnections jQuery Session Slides and Samples posted

  - by Rick Strahl

  I’ve posted all of my slides and samples from the DevConnections VS 2010 Launch event last week in Vegas. All three sessions are contained in a single zip file which contains all slide decks and samples in one place: www.west-wind.com/files/conferences/jquery.zip There were 3 separate sessions: Using jQuery with ASP.NET Starting with an overview of jQuery client features via many short and fun examples, you'll find out about core features like the power of selectors to select document elements, manipulate these elements with jQuery's wrapped set methods in a browser independent way, how to hook up and handle events easily and generally apply concepts of unobtrusive JavaScript principles to client scripting. The session also covers AJAX interaction between jQuery and the .NET server side code using several different approaches including sending HTML and JSON data and how to avoid user interface duplication by using client side templating. This session relies heavily on live examples and walk-throughs. jQuery Extensibility and Integration with ASP.NET Server Controls One of the great strengths of the jQuery Javascript framework is its simple, yet powerful extensibility model that has resulted in an explosion of plug-ins available for jQuery. You need it - chances are there's a plug-in for it! In this session we'll look at a few plug-ins to demonstrate the power of the jQuery plug-in model before diving in and creating our own custom jQuery plug-ins. We'll look at how to create a plug-in from scratch as well as discussing when it makes sense to do so. Once you have a plug-in it can also be useful to integrate it more seamlessly with ASP.NET by creating server controls that coordinate both server side and jQuery client side behavior. I'll demonstrate a host of custom components that utilize a combination of client side jQuery functionality and server side ASP.NET server controls that provide smooth integration in the user interface development process. This topic focuses on component development both for pure client side plug-ins and mixed mode controls. jQuery Tips and Tricks This session was kind of a last minute substitution for an ASP.NET AJAX talk. Nothing too radical here :-), but I focused on things that have been most productive for myself. Look at the slide deck for individual points and some of the specific samples.   It was interesting to see that unlike in previous conferences this time around all the session were fairly packed – interest in jQuery is definitely getting more pronounced especially with microsoft’s recent announcement of focusing on jQuery integration rather than continuing on the path of ASP.NET AJAX – which is a welcome change. Most of the samples also use the West Wind Web & Ajax Toolkit and the support tools contained within it – a snapshot version of the toolkit is included in the samples download. Specicifically a number of the samples use functionality in the ww.jquery.js support file which contains a fairly large set of plug-ins and helper functionality – most of these pieces while contained in the single file are self-contained and can be lifted out of this file (several people asked). Hopefully you'll find something useful in these slides and samples.© Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET  jQuery

• JSON and jQuery.ajax

  - by Andreas

  Hello, im trying to use the jQuery UI autocomplete to communitate with a webservice with responseformate JSON, but i am unable to do so. My webservice is not even executed, the path should be correct since the error message does not complain about this. What strikes me is the headers, response is soap but request is json, is it supposed to be like this? Response Headersvisa källkod Content-Type application/soap+xml; charset=utf-8 Request Headersvisa källkod Accept application/json, text/javascript, */* Content-Type application/json; charset=utf-8 The error message i get is as follows (sorry for the huge message, but it might be of importance): soap:ReceiverSystem.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Xml.XmlException: Data at the root level is invalid.

• 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.

• How to change Jquery UI Slider handle

  I want to modify the stock JQuery UI slider so that the handle has a arrow on it rather than being a square. i.e. I want to use a custom image as the handle. There are a few tutorials that do it: http://jqueryfordesigners.com/slider-gallery/ http://www.ryancoughlin.com/2008/11/04/using-the-jquery-ui-slider/ http://www.keepthewebweird.com/creating-a-nice-slider-with-jquery-ui/ But I can't get it to work. The following code results in a stationary handle image: <!DOCTYPE html> <html> <head> <link type="text/css" href="http://jqueryui.com/latest/themes/base/ui.all.css" rel="stylesheet" /> <script type="text/javascript" src="http://jqueryui.com/latest/jquery-1.3.2.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.core.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.slider.js"></script> <style type="text/css"> #myhandle {position: absolute;z-index: 100;height: 25px;width: 35px;top: auto;background: url(http://stackoverflow.com/content/img/so/vote-arrow-down.png) no-repeat;} </style> <script type="text/javascript"> $(document).ready(function(){ $("#slider").slider({handle: '#myhandle'}); }); </script> </head> <body> <div id="slider"><div id="myhandle"></div></div> </body> </html> It is as if JQuery doesn't pick up that I want to use the myhandle id for the handle. I'm wondering: Do I need a plugin for JQuery to recognise the handle option? (it is not documented in http://docs.jquery.com/UI/Slider). Or perhaps it only worked in an old version of JQuery? Any ideas?

• Jquery-UI tabs : Double loading of the default tab

  - by Stephane

  I use jqueryui-tabs to display a tabbed UI. here is how my markup looks in a MasterPage: <div id="channel-tabs" class="ui-tabs"> <ul class="ui-tabs-nav"> <li><%=Html.ActionLink("Blogs", "Index", "Blog", new { query = Model.Query, lang = Model.SelectedLanguage, fromTo = Model.FromTo, filters = Model.FilterId }, new{ title="Blog Results" }) %></li> <li><%=Html.ActionLink("Forums", "Index", "Forums", new { query = Model.Query, lang = Model.SelectedLanguage, fromTo = Model.FromTo, filters = Model.FilterId }, null) %></li> <li><%=Html.ActionLink("Twitter", "Index", "Twitter", new { query = Model.Query, lang = Model.SelectedLanguage, fromTo = Model.FromTo, filters = Model.FilterId }, null) %></li> </ul> <div id="Blog_Results"> <asp:ContentPlaceHolder ID="ResultPlaceHolder" runat="server"> </asp:ContentPlaceHolder> </div> If the content is loaded via ajax, I return a partial view with the content of the tab. If the content is loaded directly, I load a page that include the content in the ContentPlaceHolder. somewhat like this : <asp:Content ID="Content2" ContentPlaceHolderID="BlogPlaceHolder" runat="server"> <%=Html.Partial("Partial",Model) %> </asp:Content> //same goes for the other tabs. With this in place, if I access the url "/Forums" It loads the forum content in the Blog tab first, trigger the ajax load of the Blog tab and replace the content with the blog content. I tried putting a different placeholder for each tab, but that didn't fix everything either, since when loading "/Forums" it will sure load the forum tab, but the Blog tab will show up first. Furthermore, when using separate placeholders, If I load the "/Blogs" url, It will first load the content statically in the Blog contentplaceholder and then trigger an ajax call to load it a second time and replace it. If I just link the tab to the hashtag, then when loading the forum tabs, I won't get the blog content... How would you achieve the expected behaviour? I feel like I might have a deeper probelm in the organization of my views. Is putting the tabs in the masterpage the way to go? Maybe I should just hijax the links manually and not rely on jquery-ui tabs to do the work for me. I cannot load all tabs by default and display them using the hash tags, I need an ajax loading because it is a search process that can be long. So to sum up : /Forum should load the forum tab, and let the other tabs be loaded with an ajax call when clicking on it. /Twitter should load the twitter tab and let the other tabs.... the same goes for /Blogs and any tabs I would add later. Any idea to have this working properly?
