Is there a way to determine that the browser window was closed?

Question

How is it possible to identify that the browser\'s close button was clicked?

Answer 1

would this :

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

help you ?

It is in jQuery though.

you should check the link given by Demoli though, it has further information about this particular method ( and its downside ).

edit : added link.
