this event work and when I do refresh, but i need, only when I close the browser!
@Alexander Corotchi: Why do you want to know when the user closes the browser?
In my application can work more users, And when 1 user close browser a need to execute a function for exclude this user from this application.
This is not good enough. The only working solution is Browser window close event
Fail, when page change url call unload event, but no only close. unload != close.

You're looking for the onclose event.

see: https://developer.mozilla.org/en/DOM/window.onclose

note that not all browsers support this (for example firefox 2)

Events onunload or onbeforeunload you can't use directly - they do not differ between window close, page refresh, form submit, link click or url change.

The only working solution is How to capture the browser window close event?
