Hi everyone i am new to javascripting and ajax.

I was wonding if you guys can help me with something.

Basically ive got a socialengine script like facebook.

In the feed which posts what everyone is doing i would like that div which is called

HTML Code:

<div id ="userhomerefresher"></div>

How do i make it so that div refreshes every 5 seconds.

I have tried to do it like this

HTML Code:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>test code</title>
<script type="text/javascript" src="js/autorefresher.js"></script>
</head>

<body>

<div id="userhomerefresher"></div>
</body>
</html>

And i have a js file which is coded like this:

HTML Code:

// JavaScript Document

function loadXMLDoc(url)
{
// code for Mozilla, etc.
if (window.XMLHttpRequest)
  {
  xmlhttp=new XMLHttpRequest()
  xmlhttp.open("GET",url,true)
  xmlhttp.send(null)
  xmlhttp.onreadystatechange=state_Change
  }
// code for IE
else if (window.ActiveXObject)
  {
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP")
    if (xmlhttp)
    {
    xmlhttp.open("GET",url,true)
    xmlhttp.send()
    xmlhttp.onreadystatechange=state_Change
    }
  }
}

function state_Change()
{
// if xmlhttp shows "loaded"
if (xmlhttp.readyState==4)
  {
  // if "OK"
      if (xmlhttp.status==200)
      {
      document.getElementById('userhomerefresher').innerHTML=xmlhttp.responseText;
      }
  }
  
}

function init() {
window.setTimeout( "loadXMLDoc( \"other_doc.html\" );", 5000 );
// OR
// window.setTimeout( "loadXMLDoc( \"page.php?req=true\" );", 5000 );
}

This unfortunatly doesnt work.

Can someone help me and please bare in mind i am very very new to javascripting.

Thanks

Robert
