<pclass="arguement"><strong>handler(event, XMLHttpRequest, ajaxOptions)</strong>The function to be invoked.</p>
</li></ul>
<divclass="longdesc">
<p>Whenever an Ajax request completes, jQuery triggers the <code>ajaxComplete</code> event. Any and all handlers that have been registered with the <code>.ajaxComplete()</code> method are executed at this time.</p>
<p>To observe this method in action, we can set up a basic Ajax load request:</p>
<p>We can attach our event handler to any element:</p>
<pre>$('.log').ajaxComplete(function() {
$(this).text('Triggered ajaxComplete handler.');
});
</pre>
<p>Now, we can make an Ajax request using any jQuery method:</p>
<pre>$('.trigger').click(function() {
$('.result').load('ajax/test.html');
});</pre>
<p>When the user clicks the button and the Ajax request completes, the log message is displayed.</p>
<p><strong>Note:</strong> Because <code>.ajaxComplete()</code> is implemented as a method of jQuery object instances, we can use the <code>this</code> keyword as we do here to refer to the selected elements within the callback function.</p>
<p>All <code>ajaxComplete</code> handlers are invoked, regardless of what Ajax request was completed. If we must differentiate between the requests, we can use the parameters passed to the handler. Each time an <code>ajaxComplete</code> handler is executed, it is passed the event object, the <code>XMLHttpRequest</code> object, and the settings object that was used in the creation of the request. For example, we can restrict our callback to only handling events dealing with a particular URL:</p>
