[Javascript] Q on grabbing ONSUBMIT..

[David Lovering]

First off, assigning the action to a null string doesn't work very well
across a wide cross-section of browsers.  A much better method is as
follows:

action='javascript:void(null)'

To kill the submission of the form (which you've effectively set in motion
by setting the action as described), the routine called by onSubmit (or
whatever name-variation is this weeks W3C favorite) merely needs to return
false.   At least that's the way I interpret the fine print, and so far my
interpretation hasn't blown up any of my various web-apps.
