beforeClose event

[bannerplay]

Does the Window object support an event which is fired when the user clicks the close icon but BEFORE the window is actually closed? Something like jQuery-UI's beforeClose event.

i'm trying to build a conditional close.

Thanks

Not an event itself, but you can prevent the default behavior in the close event.

It has a very simple condition if you look the code. The first time it will not close, but it will on the second try.
