load data to div from a link with ajax

Hi,

I have a simple html page with a link and a div at the foot of the page. I need to be able to clear the content of the div, and then render the contents of an external file (text, html or xml is fine) to this div.

Basically, when a user clicks on this link the div will be cleared and then populated with this new text. Is this possible with Ajax, or is there a better way? I need it to be dynamic (ie: no page refreshes).

Any examples of this type of action?

Any help appreciated.

Thanks

probably...

what server side language/technology?

by external, I'm assuming this file is on the web server or can be accessed by the web server?

here is a simple example using a textbox to display the result, you'd just change it to set the innerHTML(or innerText maybe) of your div instead of the inputs .value

This one example demonstrating how it can be done locally at your system. Just create some dummy text file and test this code. You can also use HTML file but not XML file. Here is the code:

<html>
	<head>
		<title>Script Demo Gops</title>
		<style>
			body, table,input, select,span,a{font-family:verdana;font-size:xx-small;}
			body{margin:0px;padding:0px}
			#leftmenu{display:inline;width:19%;float:left:clear:right;margin-right:5px;padding-left:15px;height:500px;margin-top:20px;}
			#container{display:inline;width:80%;float:right:clear:left;margin-top:20px;height:500px;overflow:auto;}
			#leftmenu a{display:block;text-decoration:none;padding:5px 0px 5px 0px;}
			#leftmenu a:hover{text-decoration:underline}
		</style>
		<script language="javascript">
			function ajaxpage(url, containerid){
				var page_request = false
				if (window.XMLHttpRequest) // if Mozilla, Safari etc
					page_request = new XMLHttpRequest()
				else if (window.ActiveXObject){ // if IE
					try {
						page_request = new ActiveXObject("Msxml2.XMLHTTP")
					}catch (e){
						try{
							page_request = new ActiveXObject("Microsoft.XMLHTTP")
						}catch (e){}
					}
				} else return false
 
 
				page_request.onreadystatechange=function(){
					loadpage(page_request, containerid)
				}
 
				page_request.open('GET', url, true)
				page_request.send(null)
			}
 
			function loadpage(page_request, containerid){
				if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
					document.getElementById(containerid).innerHTML=page_request.responseText
			}
 
			window.onload=function(){
				ajaxpage('file1.txt', 'container');
			}
		</script>
	</head>
	<body topmargin="0" leftmargin="0" marginwidth="0" marginheight="0">
		<div id="leftmenu">
			<a href="#" onclick="ajaxpage('file1.txt', 'container');return false;">File 1</a>
			<a href="#" onclick="ajaxpage('file2.txt', 'container');return false;">File 2</a>
			<a href="#" onclick="ajaxpage('file3.txt', 'container');return false;">File 3</a>
		</div>
		<div id="container">
 
		</div>
	</body>
</html>
