How you can load jquery url in joomla (Component) ? I've one button. when click this button will reload page i quickly use get way of get value form variable to show.

JavaScript:

jQuery("#btnclickme").click(function(){
jQuery("#divpro").load("index.php?hello=hello");
});

PHP:

echo $_GET['hello'];
return;

HTML:

<input type="button" value="Click me" id="btnclickme" name="btnclickme" />
<div id="divpro"></div>

In index.php of the template in mind section (after <jdoc:include type="head" />)

<?php
$document =& JFactory::getDocument();
$document->addScript("templates/yourtemplatename/jquery/js/jquery-1.3.2.min.js");

And copy the jquery files for your templates directory.
