You would need to:

  1. Make sure you got jQuery properly loaded. Falak's approach absolutely valid, is but one of the most quicker - you need to make sure you upload your jQuery library in the _layouts/js folder prior to testing. There are other ways to load JQUery, such as using the ScriptLink (see here http://tommdaly.wordpress.com/2010/12/16/scriptlink-vs-whats-the-difference/) or a Custom Actions (see here http://weblogs.asp.net/jan/archive/2010/03/01/scriptsrc-referencing-javascript-files-with-sharepoint-2010-custom-actions.aspx)

  2. Check by code if jQuery is really loaded using either

    if (jQuery) {  
    // jQuery is loaded  
    } else  { // jQuery is not loaded }

    //or use this if (typeof jQuery == 'undefined') { // jQuery is not loaded
    } else { // jQuery is loaded }

    There are many elegant approaches where you can add controls/scripts to pages without modifying the master page, DelegateControls, ScriptLink etc., but it's up to you to decide which suits your application best. Jun 16, 2012 at 20:46

First things first, let’s make sure if you are loading a copy of the jQuery script in the application page. For e.g.

<script language="javascript" src="http://yoursite/_layouts/js/jquery-1.7.1.js" type="text/javascript"></script>

  • should i have to upload it in the same application page ??

    deploying the jQuery Script File to Layouts can easily be done via VS2010. In your Right-click your project and add a SharePoint "Layouts" Mapped Folder. Include the jQuery file and you're good to go Jun 16, 2012 at 20:39
