hihi all,
what is the best way to detect changes on a form without using any
client side methods?
i have a very typical requirement to implement something that could
warn the user that they made changes to the form but have not saved yet
these changes yet.
is the only way to do this by keeping a copy of the last saved form
data in session and then comparing this with the form data?
can anyone share any good strategies for doing this? i'd like to avoid
any client side code as much as possible, but is this a good case for
using javascript?
any comments/opinions welcome!
please and thanks,
woodchuck
