  • Jquery Form ajaxSubmit not submitting

    - by Gazler
    Hi, I am using the JQuery Form extension to submit a form with AJAX. I have the following code: var options = { beforeSubmit: showRequest, // pre-submit callback success: showResponse, // post-submit callback // other available options: //url: url // override for form's 'action' attribute //type: 'post', // 'get' or 'post', override for form's 'method' attribute //dataType: null // 'xml', 'script', or 'json' (expected server response type) clearForm: true, // clear all form fields after successful submit //resetForm: true // reset the form after successful submit // $.ajax options can be used here too, for example: timeout: 3000 }; $('#composeForm').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).find(':disabled').removeAttr('disabled'); $(this).ajaxSubmit(options); // !!! Important !!! // always return false to prevent standard browser submit and page navigation return false; }); The problem is that the form doesn't appear to be submitting, or atleast the success function is not being called. If I remove the return false, then the submission works, but the page navigates away. Is there a problem in my code that could be causing this? Cheers, Gazler.

  • AJAX in Drupal Forms?

    - by Kevin
    How would you go about constructing a step by step form that uses AJAX through Drupal to pull the next form step? For example, Step 1: I like Baseball I don't like Baseball. When that person clicks on either Like or Don't Like, I want to use AJAX to recognize and pull the next part of the form, remove/hide the first section since its not needed, and present the next section. Example: Step 1: I like Baseball *click (fade out) Step 2: My favorite team is __________ The player I like most is __________ What is the best way to do this through Drupal Form API? I know how to build the forms and modules, but I have never used AJAX yet. I know a few things exist out there that are supposed to help, but I wanted to know if anyone here has done it and how they approached it.

  • Problem with JSON, Struts 2 and Ajax.

    - by Javi
    Hello, I have an apllication with Struts 2, Spring and I want to send JSON as a response to an Ajax request, but my server in not sending the JSON in the response. I have this base package: <package name="myApp-default" extends="struts-default"> <result-types> <result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult" /> <result-type name="json" class="com.googlecode.jsonplugin.JSONResult"> <param name="enableGZIP">true</param> <param name="noCache">true</param> <param name="defaultEncoding">ISO-8859-1</param> </result-type> </result-types> </package> And another package which extends the previous one. <package namespace="/rest" name="rest" extends="myApp-default"> <action name="login" class="restAction" method="login"> <result type="json"/> </action> So I call with jQuery Ajax and debugging it I see it enters in the Action restAction in the method login and it also enters in the method getJsonData() because I have set two breakpoints and the program is stopped first in login and then in getJsonData. public class RestAction extends BaseAction { private String login; private String password; private String jsonData; public String login() { jsonData = "changed"; return Action.SUCCESS; } //I ommit getter/setters for login and password @JSON(name="jsonData") public String getJsonData() { return jsonData; } public void setJsonData(String jsonData) { this.jsonData = jsonData; } } My ajax looks like this: $.ajax({type: 'GET', url: this_url, data: pars, cache:false, success: handleResponse, error: handleError}); With firebug I see that the response to my request is completely void (though I have seen that the data saved in pars variable has been populated to the action and the methods have been executed correctly). And maybe for that reason my ajax enters in my handleError function where xmlHttpRequest.readyState is 4 and xmlHttpRequest.status is 0. Can anyone tell me what may the problem be? Thanks.

  • login form using ajax, to submit without refreshing

    - by Brad
    I am using this tutorial to create a login form http://www.ryancoughlin.com/2008/11/04/use-jquery-to-submit-form/ It authenticates against w/ our ldap server. What I am having a problem with is the line success: function(){ $('form#submit').hide(function(){$('div.success').fadeIn();}); It runs success even though we don't even know if the username and password binded successfully. Is there a way to only run success if the username and password posted was binded successfully?

  • Need advice on using Grails and Ajax to append to a div like in Rails

    - by Nate
    I'm just starting out in Grails and need some advice on using Ajax. I want to append some html to the bottom of a div inside a form. This is basically what I have: -form- -div id="listOfchildren"- childrow 1 input fields childrow 2 input fields childrow 3 input fields -/div- -form- -a-Add Child 4-/a- When I click on the "Add Child" I want to make an ajax call that results in a new childrow getting inserted into the "listOfchildren" div. So the document would look like this: -form- -div id="listOfchildren"- childrow 1 input fields childrow 2 input fields childrow 3 input fields childrow 4 input fields -/div- -form- -a-Add Child 5-/a- In Rails I would do something simple like this: render :update do |page| page.insert_html :bottom, "list_of_children", :partial = child_partial page.replace "add_link", :partial = 'add_link' end The previous code sends an javascript back to the browser with two commands. The first command tells the browser to append some html to the bottom of a div. The second command updates the "add link" counter. In grails I can only see how to replace an entire div (which would wipe out the user's existing input) and I don't see how I can call multiple functions from the ajax response. I can probably do this if I was to write some javascript functions in prototype or whatever, but I'd like to avoid that if there is a simpler way. Thanks! Nate

  • 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 ajax post callback - manipulation stops after the "third" call

    - by shanyu
    EDIT: The problem is not related to Boxy, I've run into the same issue when I've used JQuery 's load method. EDIT 2: When I take out link.remove() from inside the ajax callback and place it before ajax load, the problem is no more. Are there restrictions for manipulating elements inside an ajax callback function. I am using JQuery with Boxy plugin. When the 'Flag' link on the page is clicked, a Boxy modal pops-up and loads a form via ajax. When the user submits the form, the link (<a> tag) is removed and a new one is created from the ajax response. This mechanism works for, well, 3 times! After the 3rd, the callback function just does not remove/replace/append (tested several variations of manipulation) the element. The only hint I have is that after the 3rd call, the parent of the link becomes non-selectable. However I can't make anything of this. Sorry if this is a very trivial issue, I have no experience in client-side programming. The relevant html is below: <div class="flag-link"> <img class="flag-img" style="width: 16px; visibility: hidden;" src="/static/images/flag.png" alt=""/> <a class="unflagged" href="/i/flag/showform/9/1/?next=/users/1/ozgurisil">Flag</a> </div> Here is the relevant js code: $(document).ready(function() { $('div.flag-link a.unflagged').live('click', function(e){ doFlag(e); return false; }); ... }); function doFlag(e) { var link = $(e.target); var url = link.attr('href'); Boxy.load(url, {title:'Inappropriate Content', unloadOnHide:true, cache:false, behaviours: function(r) { $("#flag-form").live("submit", function(){ var post_url = $("#flag-form").attr('action'); boxy = Boxy.get(this); boxy.hideAndUnload(); $.post(post_url, $("#flag-form").serialize(), function(data){ par = link.parent(); par.append(data); alert (par.attr('class')); //BECOMES UNDEFINED AT THE 3RD CALL!! par.children('img.flag-img').css('visibility', 'visible'); link.remove(); }); return false; }); }}); }

  • Injecting jQuery into a page fails when using Google AJAX Libraries API

    - by jakemcgraw
    I'd like to inject jQuery into a page using the Google AJAX Libraries API, I've come up with the following solution: http://my-domain.com/inject-jquery.js: ;((function(){ // Call this function once jQuery is available var func = function() { jQuery("body").prepend('<div>jQuery Rocks!</div>'); }; // Detect if page is already using jQuery if (!window.jQuery) { var done = false; var head = document.getElementsByTagName('head')[0]; var script = document.createElement("script"); script.src = "http://www.google.com/jsapi"; script.onload = script.onreadystatechange = function(){ // Once Google AJAX Libraries API is loaded ... if (!done && (!this.readyState || this.readyState == "loaded" || this.readyState == "complete")) { done = true; // ... load jQuery ... window.google.load("jquery", "1", {callback:function(){ jQuery.noConflict(); // ... jQuery available, fire function. func(); }}); // Prevent IE memory leaking script.onload = script.onreadystatechange = null; head.removeChild(script); } } // Load Google AJAX Libraries API head.appendChild(script); // Page already using jQuery, fire function } else { func(); } })()); The script would then be included in a page on a separate domain: http://some-other-domain.com/page.html: <html> <head> <title>This is my page</title> </head> <body> <h1>This is my page.</h1> <script src="http://my-domain.com/inject-jquery.js"></script> </body> </html> In Firefox 3 I get the following error: Module: 'jquery' must be loaded before DOM onLoad! jsapi (line 16) The error appears to be specific to the Google AJAX Libraries API, as I've seen others use a jQuery bookmarklet to inject jQuery into the current page. My question: Is there a method for injecting the Google AJAX Libraries API / jQuery into a page regardless of the onload/onready state?

  • Do ASP.Net Web Forms actually produce ADA compliant HTML? Does the ASP/AJAX toolkit undermine the goal of ADA compliance?

    - by Justin984
    I'm trying to convince my employer to let us use the Microsoft ASP/AJAX toolkit since it simplifies the implementation of many controls. However they have rejected the idea on the grounds that it produces "AJAX code" which is not ADA compliant. However the same employer requires webpages to be written in ASP.NET Web Forms which, as far as I can tell from the source, is very very far from ADA compliance. I am new to both web programming and ADA compliance. My questions are: Do ASP.Net Web Forms actually produce ADA compliant HTML? Will the ASP/AJAX toolkit undermine the goal of ADA compliance?

  • I am not able to update form data to MySQL using PHP and jQuery

    - by Jimson Jose
    My problem is that I am unable to update the values entered in the form. I have attached all the files. I'm using MYSQL database to fetch data. What happens is that I'm able to add and delete records from form using jQuery and PHP scripts to MYSQL database, but I am not able to update data which was retrieved from the database. The file structure is as follows: index.php is a file with jQuery functions where it displays form for adding new data to MYSQL using save.php file and list of all records are view without refreshing page (calling load-list.php to view all records from index.php works fine, and save.php to save data from form) - Delete is an function called from index.php to delete record from MySQL database (function calling delete.php works fine) - Update is an function called from index.php to update data using update-form.php by retriving specific record from MySQL table, (works fine) Problem lies in updating data from update-form.php to update.php (in which update query is written for MySQL) I have tried in many ways - at last I had figured out that data is not being transferred from update-form.php to update.php; there is a small problem in jQuery AJAX function where it is not transferring data to update.php page. Something is missing in calling update.php page it is not entering into that page. I am new bee in programming. I had collected this script from many forums and made this one. So I was limited in solving this problem. I came to know that this is good platform for me and many where we get a help to create new things. Please find the link below to download all files which is of 35kb (virus free assurance): download mysmallform files in ZIPped format, including mysql query

  • Get value from ajax-loaded form before submitting

    - by ldvldv
    Hi, I have an app that loads an ajax form when a button is clicked. I then want to check a value in that ajax loaded form called "comment_content" so that I don't send an ajax request if the comment_content is empty. I can capture the form submission using the live method, however, I can't capture the form element because it needs an element. I was looking at livequery but was wondering if there is a more efficient way by using live or if that I shouldn't even bother? Your help is very much appreciated. $("#comment_submit").live('click', function(){ var comment = $("#comment_content").html(); if(comment == ""){ $("#notice").html("").stop(true, true); $("#notice").append("<p>Are you going to write something in that comment?</p>"); $('#notice').slideDown().delay(2000).slideUp(); return false; } return true; });

  • Issues in Ajax based applications

    - by Sinuhe
    I'm very interested in developing Ajax based applications. This is, loading almost all of the content of the application via XMLHttpRequest, instead of only some combos and widgets. But if I try to do this form scratch, soon I find some problems without an easy solution. I wonder if there is some framework (both client and server side) to deal with this issues. As far as I know, there isn't (but I've searched mainly in Java world). So I am seriously thinking of doing my own framework, at least for my projects. Therefore, in this question I ask for several things. First, the possible problems of an ajax based development. Then, I'm looking for some framework or utility in order to deal with them. Finally, if there is no framework available, what features must it have. Here are the issues I thought: 1 - JavaScript must be enabled. Security paranoia isn't the only problem: a lot of mobile devices couldn't use the application, too. 2 - Sometimes you need to update more than one DIV (e.g. main content, menu and breadcrumbs). 3 - Unknown response type: when you make an Ajax call, you set the callback function too, usually specifying if expected response is a javascript object or in which DIV put the result. But this fails when you get another type of response: for example when the session has expired and the user must log in again. 4 - Browser's refresh, back and forward buttons can be a real pain. User will expect different behaviors depending on the situation. 5 - When search engines indexes a site, only follow links. Thus, content load by Ajax won't "exist" for who doesn't know about it yet. 6 - Users can ask for open a link in a different window/tab. 7 - Address bar doesn't show the "real" page you are in. So, you can't copy the location and send it to a friend or bookmark the page. 8 - If you want to monetize the site, you can put some advertisings. As you don't refresh entire page and you want to change the ad after some time, you have to refresh only the DIV where the ad is. But this can violate the Terms and Conditions of your ad service. In fact, it can go against AdSense TOS. 9 - When you refresh an entire page, all JavaScript gets "cleaned". But in Ajax calls, all JavaScript objects will remain. 10 - You can't easily change your CSS properties.

  • jquery: How to deal with 'this' in ajax callbacks

    - by Svish
    I currently have code similar to this for a form: $('#some-form') .submit(function() { // Make sure we are not already busy if($(this).data('busy')) return false; $(this).data('busy', true); // Do post $.post("some/url", $(this).serialize(), function(data) { if(data.success) // Success is a boolean I set in the result on the server { // Deal with data } else { // Display error } $('#some-form') .removeData('busy'); }); return false; }); My issue is that I would like to somehow remove the need for knowing the form id in the post callback. In the end where I remove the busy data from the form, I'd like to somehow not have that hard coded. Is there any way I can do this? Is there a way I can hand whatever is in this to the post callback function? Since I know the id right now, I can get around it by doing what I have done, but I'd like to know how to not be dependant on knowing the id, since often I don't have an id. (For example if I have a link in each row in a table and all the rows have the same click handler.

  • Get with the ajax data into a php file

    I'm trying to build a login system with ajax and php. I use a log-view where I then save the data in ajax which brings into my doLogin.php (php file).

  • form validation without reset

    - by Paulo Bueno
    Hi guys Is there a way to check the data sent by a form to a PHP page return to the form page WITHOUT resetting the data sent and show a error? The form has 20 fields and I need to check one of them on a bd. If it fails the user may be redirected to the form page with the form populated and displaying a error message on the field which is 'wrong'. I would like any advice of a technique instead of populating each field using PHP.

  • JQuery getJSON - ajax parseerror

    - by JW
    I've tried to parse the following json response with both the JQuery getJSON and ajax: [{"iId":"1","heading":"Management Services","body":"<h1>Program Overview</h1><h1>January 29, 2009</h1>"}] I've also tried it escaping the "/" characters like this: [{"iId":"1","heading":"Management Services","body":"<h1>Program Overview <\/h1><h1>January 29, 2009<\/h1>"}] When I use the getJSON it dose not execute the callback. So, I tried it with JQuery ajax as follows: $.ajax({ url: jURL, contentType: "application/json; charset=utf-8", dataType: "json", beforeSend: function(x) { if(x && x.overrideMimeType) { x.overrideMimeType("application/j-son;charset=UTF-8"); } }, success: function(data){ wId = data.iId; $("#txtHeading").val(data.heading); $("#txtBody").val(data.body); $("#add").slideUp("slow"); $("#edit").slideDown("slow"); },//success error: function (XMLHttpRequest, textStatus, errorThrown) { alert("XMLHttpRequest="+XMLHttpRequest.responseText+"\ntextStatus="+textStatus+"\nerrorThrown="+errorThrown); } }); The ajax hits the error ans alerts the following: XMLHttpRequest=[{"iId":"1","heading":"Management Services","body":"<h1>Program Overview </h1><h1>January 29, 2009</h1>"}] textStatus=parseerror errorThrown=undefined Then I tried a simple JQuery get call to return the JSON using the following code: $.get(jURL,function(data){ var json = eval("("+data+");"); wId = json.iId; $("#txtHeading").val(json.heading); $("#txtBody").val(json.body); $("#add").slideUp("slow"); $("#edit").slideDown("slow"); }) The .get returns the JSON, but the eval comes up with errors no matter how I've modified the JSON (content-type header, other variations of the format, etc.) What I've come up with is that there seem to be an issue returning the HTML in the JSON and getting it parsed. However, I have hope that I may have missed something that would allow me to get this data via JSON. Does anyone have any ideas?

  • jQuery $.ajax Not Working in IE8 but it works on FireFox & Chrome

    - by Sam3k
    I have the following ajax call which works perfectly in Firefox and Chrome but not IE: function getAJAXdates( startDate, numberOfNights, opts ) { var month = startDate.getMonth() + 1; var day = startDate.getDate(); var year = startDate.getFullYear(); var d = new Date(); var randNum = Math.floor(Math.random()*100000000); $.ajax({ type : "GET", dataType : "json", url : "/availability/ajax/bookings?rand="+randNum, cache : false, data : 'month='+month+'&day='+day+'&year='+year+'&nights='+numberOfNights, contentType : 'application/json; charset=utf8', success : function(data) { console.log('@data: '+data); insertCellData(data, opts, startDate); }, error:function(xhr, status, errorThrown) { console.log('@Error: '+errorThrown); console.log('@Status: '+status); console.log('@Status Text: '+xhr.statusText); } }); } I know for a fact that all the variables are passing the right content and $.ajax is indeed passing all the paramater/values. This is what I get on error: LOG: @Error: undefined LOG: @Status: parsererror LOG: @Status Text: OK I'm aware of the cache issue on IE and implemented a random paramater to clear it up. Finally these are the headers that are sent back from the backend: header('Content-Type: application/json; charset=utf8'); header("Cache-Control: no-cache"); header("Expires: 0"); header('Access-Control-Max-Age: 3628800'); header('Access-Control-Allow-Methods: GET, POST, PUT, DELETE');

  • Try/Catch with jquery ajax request

    - by Anthony
    I am trying to build a Google Chrome extension that makes an ajax request. Something similar to the GMail Checker extension. The problem is that when I do the request using jquery, and I put in the wrong username/password, it fails silently, with the error callback function ignored. If I move the ajax call out of the background.html script (where I can't see the requests in the developer window), to the options.html script, I get a dialog box to re-authenticate. If I hit cancel, THEN the jquery error callback fires. But in the original model extension (again, the Gmail checker), they use plain (non-jquery) ajax calls with a try/catch, and if I put in the wrong credentials, I get an alert saying as much. I tried wrapping the entire jquery call in a try/catch, like so: try { $.ajax({ type: "POST", url: someurl, contentType : "text/xml", data: somedata, username: user, password: pass, success: function(data,status,xhr){ alert("Hurrah!"); }, error: function(xhr, status, error){ alert("Error!" + xhr.status); }, dataType: "xml" }); } catch(e) { alert("You messed something up!"); } But still nothing. Is the error due to it being asynchronous, or is Chrome not returning the request as an error since it wants to re-prompt for credentials? Or do I just not know how to use try/catch? Update Here is a very slimmed down version of how the model code does the request: var req = new XMLHttpRequest(); req.onreadystatechange = function() { try { if ( req.readyState == 4 ) { //Do some stuff with results } } catch (ex) { alert('Error parsing response.'); } } try { req.send (data); } catch (ex) { alert ('Something went wrong with the request.'); }

  • ajax call to servlet puzzler

    - by vector
    Greetings! I'm having a problem getting a text value of a captcha from a servlet through ajax call. When my captcha gets created, its text value is written to session, but after refreshing the image itself though ajax call, I only get one old value of the text. Refreshing the image itself works ok, but I'm stuck getting the correct values from the session on subsequent call. On page reload I get both the new image and its new text value, no joy with ajax though. This works great for the image refresh: $("#asos").attr("src", "/ImageServlet?="+((new Date()).getTime()) ) This call to another method to get text value gives me old stuff: $.ajax({ url:"checkCaptcha", type:"GET", cache: false, success: function( data) { alert(data); } }); Any feedback will be appreciated. ps: here's the meat of the method getting the call: PrintWriter out = response.getWriter(); response.setContentType("text/html"); response.setDateHeader("Expires", 0 ); // Set standard HTTP/1.1 no-cache headers. response.setHeader("Cache-Control", "no-store, no-cache, must-revalidate"); // Set IE extended HTTP/1.1 no-cache headers (use addHeader). response.addHeader("Cache-Control", "post-check=0, pre-check=0"); // Set standard HTTP/1.0 no-cache header. response.setHeader("Pragma", "no-cache"); out.print( request.getSession( ).getAttribute("randomPixValue") ); out.close();

  • Retrieving image from database using Ajax

    - by ama
    I'm trying to read image from database with Ajax, but I could not read the xmlhttp.responseText to the img src. The image is saved as binary data in database and also retrieved as binary data. I'm using Ajax in JSP, because I want to give the user the ability to upload images and I will view the last uploaded image, on mouse over action the Ajax will be activated and get the image back, the problem is in reading the img from the response. This is the Ajax function: function ajaxFunction(path) { if (xmlhttp) { var s = path; xmlhttp.open("GET", s, true); xmlhttp.onreadystatechange = handleServerResponse; xmlhttp.send(null); } } function handleServerResponse() { if (xmlhttp.readyState == 4) { var Image = document.getElementById(Image_Element_Name); document.getElementById(Image_Element_Name).src = "data:" + xmlhttp.responseText; } } I also got exception in the server: 10415315 [TP-Processor1] WARN core.MsgContext - Error sending end packet java.net.SocketException: Broken pipe at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92) at java.net.SocketOutputStream.write(SocketOutputStream.java:136) at org.apache.jk.common.ChannelSocket.send(ChannelSocket.java:537) at org.apache.jk.common.JkInputStream.endMessage(JkInputStream.java:127) at org.apache.jk.core.MsgContext.action(MsgContext.java:302) at org.apache.coyote.Response.action(Response.java:183) at org.apache.coyote.Response.finish(Response.java:305) at org.apache.catalina.connector.OutputBuffer.close(OutputBuffer.java:281) at org.apache.catalina.connector.Response.finishResponse(Response.java:478) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:154) at org.apache.jk.server.JkCoyoteHandler.invoke(JkCoyoteHandler.java:200) at org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:283) at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:773) at org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:703) at org.apache.jk.common.ChannelSocket$SocketConnection.runIt(ChannelSocket.java:895) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:685) at java.lang.Thread.run(Thread.java:619) 10415316 [TP-Processor1] WARN common.ChannelSocket - processCallbacks status 2

  • Run ajax scripts on page when navigating with ajax?

    - by Oskar Kjellin
    I got a bit of an issue in my ASP.NET MVC project. I have a chat div in the bottom right corner (like facebook), and of course I do not want this to reload when navigating to all my navigation is ajax. The problem I am facing is that I use the following code on the top of the view page: <script type="text/javascript"> $(document).ready(function() { $('#divTS').hide(); $('a#showTS').click(function() { $('#divTS').slideToggle(400); return false; }); }); </script> The problem is that this code is only loaded with ajax and does not seem to fire? I would like to run all scripts in the newly loaded view, just as if I hadn't navigated with ajax. I cannot put this in the site.master as it only loads once and then probably the divs I am trying to hide doesn't exist. Is there a good way to run scripts in the ajax-loaded div?
