This example demonstrates how a <tt>PageAction</tt> can be used to handle and respond
to an Ajax request.

<p/>

Click $link to call the server using Ajax.

<div id="result">
    <!-- Ajax response will be set here -->
</div>

<script type="text/javascript" src="$context/assets/js/jquery-1.4.2.js"></script>

<script type="text/javascript">
    // This example uses jQuery for making Ajax requests:
    // http://api.jquery.com/jQuery.get/
    // http://api.jquery.com/jQuery.ajax/

    // Register a function that is invoked as soon as the DOM is loaded
    jQuery(document).ready(function() {

        // Register a 'click' handler that makes an Ajax request
        jQuery("#link-id").click(function(event){
            // Make ajax request
            makeRequest();

            // Prevent the default browser behavior of navigating to the link
            return false;
        })
    })

    function makeRequest() {
        var link = jQuery('#link-id');
        var url = link.attr('href');
        // Set the pageAction to the onLinkClicked method in the Java Page class.
        var extraData = 'pageAction=onLinkClicked';
        jQuery.get(url, extraData, function(data) {
            // 'data' is the response received from the server

            // We select the div element with the ID 'result' and set its
            // content to the server response
            jQuery("#result").html("<p class='infoMsg'>" + data + "</p>");
        });
    }
