  • Prototype's Ajax.Request not working in Chrome

    - by Jason
    I am just doing a simple Ajax.Request call using the newest version of Prototype. It works fine in Firefox, Internet Explorer, and even Safari... but not in Chrome. Here is my code... alert(url); new Ajax.Request(url, { method: 'get', onSuccess: function(transport) { alert('test'); } }); It pops up he URL alert but the test alert never comes up. Like I said it does in every other browser. I am not getting any javascript errors and I have used Firebug. I did a console.log on each event and it gets to the onLoading stage of Ajax.Request but never onLoaded. Very confused... ?

    - by Beginner
    I'm trying to write an application with Symfony and I'm new to it. I have an ajax call in this application. The problem is that it always fires error call back . I put breakpoint in netbeans IDE and can see that error callback is fired before firing the specified action in the url property of ajax. action code: public function userNameExistsAction() { return 'success'; } javascript: $('#register_submit').click(function(){ var path = '/symfony/web/app_dev.php/account/userNameExists'; //var userName = $('#register_userName').val(); $.ajax({ url: path, type: 'GET', success: function(){ alert('success');}, error: function() { console.log('error'); } }); }); Any help is appreciated in advance.

  • How to read directory using jQuery .ajax()?

    - by C.W.Holeman II
    Using jQuery .ajax() to read "./ex.html" returns the expected contents of the file. Using the same call just changing the request to "./" does not return an expected directory listing. <html> <head> </head> <body> <script type="text/JavaScript" src="jquery.js"></script> <script type="text/JavaScript"> alert($.ajax({type: "GET", url: './ex.html', async: false}).responseText); alert($.ajax({type: "GET", url: './', async: false}).responseText); </script> </body> </html>

  • Google Chrome + Ajax

    - by teehoo
    Im writing an ajax web app that uses Comet/Long Polling to keep the webpage up to date, and I noticed in Chrome, it treats the page as if its always loading (icon for the tab keeps spinning). I thought this was normal for Google Chrome + Ajax because even Google Wave had this behaviour. Well today I noticed that Google Wave no longer keeps the loading icon spinning, anyone know how they fixed this? Here's my ajax call code var xmlHttpReq = false; // Mozilla/Safari if (window.XMLHttpRequest) { xmlHttpReq = new XMLHttpRequest(); } // IE else if (window.ActiveXObject) { xmlHttpReq = new ActiveXObject("Microsoft.XMLHTTP"); } xmlHttpReq.open('GET', myURL, true); xmlHttpReq.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); xmlHttpReq.onreadystatechange = function() { if (xmlHttpReq.readyState == 4) { updatePage(xmlHttpReq.responseText); } } xmlHttpReq.send(null);

  • Return value from ajax call?

    - by Dan
    Hi, I'm making a basic ajax function in jquery which echoes the number of rows found in a MySQL Query. function checkEventIDClass(id) { var params = 'method=checkEventIDClash&table=test&id=' + id; $.ajax({ type: "POST", url: "ajax.php", data: params, success: function(result){ return result; } }); } Is it possible to use this returned value in another function? I have tried but only get undefined values. In this situation, it will be acceptable to use synchronous calls. Any advice appreciated. Thanks

  • Performing AJAX calls on the "new" controller

    - by shmichael
    In my rails app, I want to have a sortable list as part of an object creation. The best practice suggested Railscast adds the acts_as_list plugin and then initiates AJAX calls to update item position. However, AJAX calls won't work on an unsaved model, which is the situation with new. One solution would be to save the model immediately on new and redirect to edit. This would have a nice side effect of persisting any change so the user could resume work should he be interrupted. However, this solution adds the unwanted complexity of saving an invalid model, compromising rails' validation processes. Is there any better way to allow AJAX + validations without going into too much work?

  • $.(ajax) wrapper for Jquery - passing parameters to delegates

    - by gnomixa
    I use $.(ajax) function extensively in my app to call ASP.net web services. I would like to write a wrapper in order to centralize all the ajax calls. I found few simple solutions, but none address an issue of passing parameters to delegates, for example, if i have: $.ajax({ type: "POST", url: "http://localhost/TemplateWebService/TemplateWebService/Service.asmx/GetFoobar", data: jsonText, contentType: "application/json; charset=utf-8", dataType: "json", success: function(response) { var results = (typeof response.d) == 'string' ? eval('(' + response.d + ')') : response.d; OnSuccess(results, someOtherParam1, someOtherParam2); }, error: function(xhr, status, error) { OnError(); } }); The wrapper to this call would have to have the way to pass someOtherParam1, someOtherParam2 to the OnSuccess delegate...Aside from packing the variables into a generic array, I can't think of other solutions. How did you guys address this issue?

  • Conflicts with jQuery and the ToolkitScirptManager?

    - by RUtt
    It just started experimenting with the ajax.net ToolkitScirptManager and it works fine but then I realized that it is breaking my ajax calls I'm doing using the jQuery library. I'm guessing that it is the issue with the $ symbol, does anyone have anythoughts on how to use both libraries. I don't want to use jquery's noconflict mode because we use other jquery plugins that I'm afraid won't work. Any thoughts?

  • JQuery.ajax success function returns empty

    - by viatropos
    I have a very basic AJAX function in JQuery: $.ajax({ url: "http://www.google.com", dataType: "html", success: function(data) { alert(data); } }); But the data is always an empty string, no matter what url I go to... Why is that? I am running this locally at http://localhost:3000, and am using JQuery 1.4.2. If I make a local response, however, like this: $.ajax({ url: "http://localhost:3000/test", dataType: "html", success: function(data) { alert(data); } }); ...it returns the html page at that address. What am I missing here?

  • Make element visible on ajax in JSF2

    - by amorfis
    I have dataTable in my page. Initially I want it to be hidden, and show after fetching data by AJAX request. I know how to fetch data and put into table, but I don't know how to show table if it is hidden. Here is the code: <h:commandButton value="aa"> <f:ajax execute="from to validTo" render="transportOffers"/> </h:commandButton> <p:dataTable id="transportOffers" value="${cargoOffer.transportsForCargo}" var="transport"> <p:column> <h:outputText value="${transport.company}"/> </p:column> </p:dataTable> Table is visible initially, even if it is empty. If I set rendered="false" it is invisible, and remains invisible also after AJAX request. How can I make it hidden initially, and to show up after populating with data?

  • Drupal. Use AJAX to update view's content

    - by ozke
    Hi, I've created a view in Drupal that retrieves a list of nodes. The display of this view is a page and it works perfectly well. It does even allow me to filter its content by argument. See the current's view configuration (click to enlarge): I want to use AJAX to use the filter (by parameter) functionality without reloading the page. I've enabled the "Use AJAX" option but I am not sure on how to continue. Any ideas on how to do that? By the way, I'm building my own theme (in case that changes anything). Thanks in advance Update: Basically, this view works when I browse through section/parameter1, section/parameter2... but I want to do the same with AJAX, without reloading the page. I hope is clearer now

  • Pass dynamic data to mvc controller with AJAX

    - by Yustme
    How can I pass dynamic data with an AJAX call to an MVC Controller? Controller: public JsonResult ApplyFilters(dynamic filters){ return null; } The AJAX call: $(':checkbox').click(function (event) { var serviceIds = $('input[type="checkbox"]:checked').map(function () { return $(this).val(); }).toArray(); //alert(serviceIds); $.ajax({ type: 'GET', url: '/home/ApplyFilters', data: JSON.stringify({ name: serviceIds }), contentType: 'application/json', success: function (data) { alert("succeeded"); }, error: function (err, data) { alert("Error " + err.responseText); } }); //return false; }); Ideally would be that the filters would contain the serviceIds as a property For example like this: filters.ServiceIds. I got another filter for a date range and that one would be added like so: filters.DateRange. And server side get the filter as a dynamic object in the ApplyFilters()

  • Jquery .Ajax error when trying to POST data in ASP.NET MVC

    - by GB
    I am unable to access an action in my controller using .ajax. The code works on my development machine but as soon as I place it on the server it gives the error 401 Unauthorized. Here is a snippet of the code in the .aspx file... var encoded = $.toJSON(courseItem); $.ajax({ url: '<%= Url.Action("ViewCourseByID", "Home") %>/', type: "POST", dataType: 'json', data: encoded, //contentType: "application/json; charset=utf-8", success: function(result) { Update: The only time this doesn't work is when I pass json data to the Ajax call, it works fine with HTML data.

  • jQuery 1.4.2 - Ajax & increasing IE 8 Process Handles

    - by mac866
    Hi, I'm requesting every second some data over $.ajax. $.ajax({ type: "POST", url: "ServiceEndpointUrl", data: "", success: function(result) { ... Do Work ... } } } } }); This code leads into an continuous growing number of handles in IE 8 (Windows 7 / verified with Task Manager & Process Explorer). Firefox & Chrome does not have this problem. This page is displayed all day long - this leads into thousands of handles & will sometimes crash the complete browser. My workaround is to reload the complete page every hour - but this can't be the solution ;-) Any suggestions how to "close" these Ajax-Handles? thx

  • CakePHP: Ajax view problem (nothing in the view showing)

    - by Adim
    I created a function in my controller called addToPlaylist($songName). I wanted to add these song names to an array and then a session variable using an Ajax call. The first time i did this i got an error saying i do not have a template file to display in the chosen div ("add_to_playlist.ctp was missing"). I created this file and everything seemed to be working correctly. Basically I went to bed woke up and it is broken (it is possible I changed something before I went to bed). The problem now is that it does not show anything when i click the ajax link. when i click on the ajax link it seems to call the function but nothing displays in the view (except debug info) even when i delete the view (add_to_playlist.ctp) i get no errors, I just see debug info now.

  • 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; });

  • Bookmarkabale ajax calls with MVC routing

    - by devzero
    I have a page with a menu that uses JQuery AJAX calls to populate the page with. To reflect any changes I update the URL with a #... instead of ?... or /... So an URL that originally reads : htpp://localhost/pages/index/id=1 would look like : http://localhost/#pages/index/id=1. If a user bookmarks this, and later comes back to the page, I wonder if it's possible to use the second URL in my route decoding, or if I have to load it blank, then use the same JS/Ajax to populate the page? In my mind it is problematic to use Ajax in these cases if a user copies the link and mails it to a friend with JavaScript disabled. edit#1: Fixed some spelling.

  • IE8 + Jquery ajax call giving parsererror from dJango : for json data which seems valid in Firefox

    - by PlanetUnknown
    The ajax call works fine in FF. the data returned is in JSON here is an example from FF firebug - {"noProfiles": "No profiles have been created, lets start now !"} When I try to print the error in IE8 (& in compatibility modes as well), it says "parsererror". But the output seems to be valid JSON. Here is the ajax function call I'm making. Any pointers would be great ! $.ajax({ type: "GET", url: "/get_all_profile_details/", data: "", dataType: "json", beforeSend: function() {alert("before send called");}, success: function(jsonData) { alert("data received"); }, error: function(xhr, txt, err){ alert("xhr: " + xhr + "\n textStatus: " + txt + "\n errorThrown: " + err); } }); The alerts in the error function above give - xhr:<blank> textstatus:parsererror errorThrown: undefined Any pointers would be great ! Note : jquery : 1.3.2
