Latest Threads on Forumhome with Ajax.

[Lizard King]

I am trying to add Ajax to Chris M's Latest Threads on Forumhome plugin because i found this is a great add on for forumhome. My problem i am not a coder at all maybe i can call myself as a beginner :smoke:
I've read a lot of tutorials about Ajax and here is the part which i am stuck at. The threadbits i am trying to get is a plugin and i need a php to recall the data. Is there a way to skip this part ?

		<script language="JavaScript" type="text/javascript">
			var sendReq = getXmlHttpRequestObject();
			var receiveReq = getXmlHttpRequestObject();
			var lastMessage = 0;
			var mTimer;
			//Function for initializating the page.
			function startthreads() {
				document.getElementById('threadbits').focus();
				getthreadbits();
			}		
			function getXmlHttpRequestObject() {
				if (window.XMLHttpRequest) {
					return new XMLHttpRequest();
				} else if(window.ActiveXObject) {
					return new ActiveXObject("Microsoft.XMLHTTP");
				} else {
					document.getElementById('p_status').innerHTML = 'Status: Cound not create XmlHttpRequest Object.  Consider upgrading your browser.';
				}
			}
			
			//Gets the current messages from the server
			function getthreadbits() {
				if (receiveReq.readyState == 4 || receiveReq.readyState == 0) {
					receiveReq.open("GET", 'whatinhere' + lastthread, true);
					receiveReq.onreadystatechange = handleReceivethreads; 
					receiveReq.send(null);
				}			
			}</script>

Help will be really appriciated.
