An alert box is a system convention that users will understand (or need to learn) if they use the system at all. So from that perspective it should make sense.

And you should have server-side validation in any case, because no everyone will have scripting turned on and it is generally helpful to validate the data before trying to process it further (for security if nothing else). just my tuppeny'orth Chaals On Mon, 9 Sep 2002, Steve Vosloo wrote: > >I have form that uses JavaScript to perform client-side validation, i.e. >when the user hits submit without filling in the first name an alert box >pops up.
