onbeforeunload 在每个页面打开后调用

我对 onbeforeunload 有疑问。我只想在关闭浏览器后删除一些表的数据。它适用于所有浏览器，但不适用于 IE。当我在 IE 中工作时，如果我转到另一个链接，onbeforeunload 函数就会执行，但其他浏览器只有在关闭后才会执行。

我的代码是

<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="fnUnloadHandler()">
</body>

请帮帮我..
