Sure, but this does not imply that (unobstrusive) client-side validation
must not be done. If it degrades well on non-JS user-agent it can provide a
better usability for the website, saving the user from extra server
roundtrips. But you'll have to implement the validation twice (client-side
JavaScript, server-side whatever) and keep these implementations in sync.
What the OP should do, to do form validation:
<INPUT TYPE="Submit" NAME="Submit" VALUE="Login" onclick="return
validateForm()">
where validateForm() returns 'false', if validation failed.
