Unfortunately you have to use the "built in" window.onbeforeunload method.

Yes it does look like crap but it's the standard box and if the
browsers allowed you to just do anything when someone tried to close a
window it would be more of a security risk (think uncloseable
windows).

The only time you "have" to use the onbeforeunload is to handle the
user either closing the window on using some of the other browser
buttons (back, forward, etc).

For everything else you can get away with tagging each link (or
button) on the page with a handler that checks to see if it should put
up a dialogue.
