jQuery:

$(window).unload( function () { alert("Bye now!"); } );

or javascript:

window.onunload = function(){alert("Bye now!");}

You're looking for the onclose event.

see: https://developer.mozilla.org/en/DOM/window.onclose

note that not all browsers support this (for example firefox 2)

Events onunload or onbeforeunload you can't use directly - they do not differ between window close, page refresh, form submit, link click or url change.

The only working solution is How to capture the browser window close event?
