Let's all try over-reacting...
Anyway, both sides are correct - you can't rely on Javascript in all cases,
and it's excellent for validating client-side form entry where it's
available. The result? You validate on the client side when you can, and on
each submission, you STILL check the input for correctness, just in case
Javascript isn't available. That way, if the client DOES have Javascript,
they have fewer round trips, and if they don't have Javascript, you still
manage to catch errors before they happen.
