Now, with the onbeforeunload event, I can handle this quite easily in IE, but in FireFox, it's another matter. For one thing, FireFox seems to empty out its event object on a page unload, so it's very hard to track keystrokes, etc.
Anyway, so far I've got some decent code going, but neeed a little help. If there ANY way to test in FireFox when the browser is being closed? In IE, we can get clientY and if it's < 0, then the user is most likely clicking the close button.
Also, is there a way to test in either browser what the target url is when the page is unloading? Thanks for your help!
Current Code:
Currently works in IE for:
Alt+F4 keystroke, kill button click, and knows when the page is being unloaded (but not to where)
Works in FireFox for: Alt+F4 keystroke (with some rigging) and knows when the page is being unloaded ( but not by kill button or nav away from site)
