: : How exactly does this work???????
: Not always : (
: When you change the location, either by clicking a link, pressing back, typing in a new url, choosing an entry for the browser history, then before the old page leaves it will trigger the unload event handler.
: To control what happens you can specify in the body tag, and possibly frame tag, what you want to happen. For example:
: <BODY onUnload="alert ('Bye')">
As true as that is, that's really the only place you can use. I find it's more useful to use onMouseDown and onMouseUp (due to the infamous uncooperativeness of onClick) event handlers for most things someone might try to tie to an onUnload.
