It's not possible. You can detect when an unload occurs, but you can't detect what caused the unload and you can't cancel it without the user's consent. For instance, typing a new address in the address box, clicking a link, submitting a form, selecting a bookmark or refreshing the page will all fire an onbeforeunload event.
