<script language="javascript">
function fnUnloadHandler() {
xmlhttp=null; 
if (window.XMLHttpRequest) 
  {// code for Firefox, Opera, IE7, etc. 
     xmlhttp=new XMLHttpRequest(); 
  } 
else if (window.ActiveXObject) 
 {// code for IE6, IE5 
    xmlhttp=new ActiveXObject("Msxml2.XMLHTTP"); 
 } 

if (xmlhttp!=null) 
 {  
    xmlhttp.open("GET","http://yourhost/del_cart_actionFile.php",true); 
    xmlhttp.send(null); 
 } 
 else 
 { 
    alert("Your browser does not support XMLHTTP."); 
 } 
}
</script>
 <body onbeforeunload="fnUnloadHan开发者_Go百科dler()">

You can go for the jQuery library, it is based on javascript, it handles all these browser incompatibilities for you.
