I have a web document which has multiple forms.
User can change data in these forms.
If user tries to change the page to someother, I want to check (before user
can change the page) whether data on forms has been changed (which I can
do by checking values of each element and matchiung agains defaultvalue),
and then submit all those forms which have been chnaged. I can't deicde which
event to use to checl whether forms have been changed and submit them. Moreover
I want to submit multiple forms on the same document together but get back
the results of one form only which I deicde..
How can I do that?
