XMLHttpRequest return the page code

[ts_ecommerce]

Hi:

 

I'm working on adminitrative module that works with ajax. I have a simple php with "echo functions" and a javascript file that call that .php. I do this other times, but with oscommerce the "responseText" is the current page html code (with the changes).

 

EDIT with some code:

 

Admin page:

<a class="refresh" href="#" title="refresh" onclick="fajax();return false;">Refresh</a>
<div id="div_refresh">TEXT</div>

 

JavaScript function:

function fajax(){
   var content_div_id = 'div_refresh';
   contenedor = document.getElementById(content_div_id);
   if(contenedor == null) return false;
   contenedor.innerHTML = 'Loading...';
   var source = 'folder/ajaxfunc.php'; //That folder in 'admin/includes'
   var xhr = "new XMLHttpRequest";
   xhr.open('GET', source, false);
   xhr.send('');
   contenedor.innerHTML = xhr.responseText;
   return xhr.responseText;
}

 

PHP file (ajaxfunc):

<?php
echo "REFRESH!!!";
?>

 

And, like I said, the "xhr.responseText" returns the current page html code with the changes, but I only want the php "echo". I don't understand. Another echo?

 

Does anyone have any idea that could be happening?

 

Thanks for your time and sorry for my english.
