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

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

Tone
