Ask user before closing the browser - IE and Mozilla

If you would like to ask the user for confirmation before closing the browser , then here's how to do so. You can use this script on an ASP.NET page or a simple HTML page. The code has been tested on IE 7 and Firefox 3+


<head runat="server">


<title></title>


<script type="text/javascript">


window.onbeforeunload = function() {


if (window.event)


window.event.returnValue = 'Thank you for visiting us!';


else


return 'Thank you for visiting us!';


}


</script>


</head>
