I think it's forbidden.In modern browsers, any action want to stop closing window is impossible.

some actions such as window.showModalDialog(), window.alert(), window.confirm(),window.prompt() are ignored in onunload or onbeforeunload event.

And, if u can do these actions, means you can make the browser can't be closed. it's dangerous for users
