I want to raise an event when a popup window is closed, or preferably, just before closing. I\'m storing the popup window object as an object, but I don\'t know of any way to bi

I think I figured out what's happening:

When you use window.open it opens a new window with location "about:blank" and then changes it to the url you provided at the function call.

So, the unload event is bound before the change from "about:blank" to the right url and is fired when the changing occurs.

I got it working with JQuery doing this:

$(function(){
    var win = window.open('http://url-at-same-domain.com','Test', 'width=600,height=500');
    $(win).unload(function(){
        if(this.location == 'about:blank')
        {
            $(this).unload(function(){
                // do something here
            });
        }
    });
});
