i agree with brian.
i still need to enhance my skills w/ javascirpt, but i think in the case of
validation, a simple
solution is to write generic validation components in javascript. then
simply dynamically
include the ones you need for a particular form.
as far as the javascript knowing how to locate the form fields i think its a
matter of defining
a naming convention w/in your system.
