unload Issue in IE 9.0

I am using the following code to check onunload event in Jquery

It works great on FF, CHROME, but doesnt display the alert on IE9 when the window is closed. Any workaround ?开发者_C百科

You can use beforeunload

$(window).bind("beforeunload", function() { alert("Bye now!"); });

But be careful if you need to submit a form on that page: How to capture the browser window close event?

Well, try onbeforeunload (Microsoft thingy)

$(window).bind("onbeforeunload", function(){
    alert('Bye now!');
});
