Well, I am not sure what you are exactly doing to save the data. But to make the event beforeunload to work for other browsers, have a look at this link[^]. Though, it talks for FF, but works same for others browsers as well.

Though, it is off topic but lately I have been loving jQuery [^]for its capability to handle these cross broswer implementation. With jQuery you can do something like this.

$(document).ready(function ()
{
    jQuery(window).bind('beforeunload', function ()
    {
        //save my data
        SaveData();
    });
});

EDIT: adding more explanation to OPs question to where to write this code?

add this code in the head section. also look at https://developer.mozilla.org/en/DOM/window.onbeforeunload

XML

<head>
<script>
window.onbeforeunload = function (e)
{
  var e = e || window.event;
  // For IE and Firefox prior to version 4
  if (e) {
    e.returnValue = 'Any string';
  }
  // For Safari
  return 'Any string';
};
</script>
</head>

Hi Rachit,

OnBeforeUnload appears to be one of those Microsoft IE quirks they have developed. It only works in IE and Safari so far as I can tell. However, the standard event is OnUnload. This owkrs in the 3 other mian browsers; Firefox, Opera and Google Chrome. The code I managed to get working in all browsers was:

HTML

<html>
<head>
<title></title>
<script type="text/javascript">
    function Closing()
    {
        alert('Closing');
    }
</script>
</head>

<body onunload="Closing();" onbeforeunload="Closing();">
</body>
</html>

So simply replace the alert in the closing method with your save data code.

Hope this helps,

Ed :)
