Resolved Replacing DIV content

Hi there, I'm very new to AJAX and can't manage to work this out, so any help would be fantastic.

I want to be able to change the content of a DIV (the text within it) once a link is pressed. I was doing it with an onclick method but I don't want the page to jump to the top.

I found this which I'm guessing is along the same lines, but i don't want to call a text/XML document... i would like a php string to be echoed instead. Is this possible?

Code:

<script type="text/javascript">
function loadXMLDoc()
{
var xmlhttp;
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("myDiv").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","ajax_info.txt",true);
xmlhttp.send();
}
</script>
</head>
<body>

<div id="myDiv"><h2>Let AJAX change this text</h2></div>
<button type="button" onclick="loadXMLDoc()">Change Content</button>

It is beyond my abilities and I have been trying this for the last few hours so any advice would be great.

thank you!!

Pat.

So did you try to replace the string "ajax_info.txt" with the name (and path if necessary) of your PHP file that echoes some string? Because that would have worked ...

I didn't, but thank you. That works perfectly.
