291889 - Back / Forward should warn user if form values are modified

Status: NEW

(Core :: DOM: Navigation, defect)

Description

[Darin Fisher]

Back / Forward should warn user if form values are modified.  Have you ever been
editing a textarea and inadvertantly pressed the back/forward buttons on your
IBM thinkpad by accident (or the backspace for that matter)?  It really sucks if
the contents of the web form aren't restored when you hurredly press forward
(think patch editor, hotmail message compose, etc.).  I think we should warn the
user in this case since it could really make a difference.  This would help me,
and I suspect it would help others too.  We could restrict this checking to
forms that have a textarea.

We should only prompt if the form data is going to be thrown out. In most cases
it'll be preserved (especially now we havthe back/forward cache).
