How can I warn a user they are about to navigate away from a page

[Tone Curtis]

I have a set of webforms where I need to prompt the user to "Save Changes".
I can handle this to a degree within the form but if the user presses the
Back button or selects the Home button the data can be lost.

I have tried using javascript but that only seems to capture an event
signalling that you are leaving the page, I want something that is fired
before it navigates away. I have tried using blur events but they fire when
I switch to another window.

Has anyone out there encountered this or come up with a solution to this.

Thanks

not really. This of it this way, if you could you could stop somone from
EVER leaving...that wouldn't be good. You can have a dialog on the controls
in your page easy enough but not stopping the actual browser controls......

I'm afraid that the solution to this problem is to not use a web
application. This is not what web applications do.

What would you do if the user closed the browser? What if he turns off his
computer?

Thanks for the advice. That makes perfect sense.
