I agree that JavaScript really isn't the best way to validate this. As
long
as you're doing CGI, why not do a POST to the same script, evaluate,
the answers, and complain if they're not any good?
With regards to the multiple fields, I think he's only running into
problems
if someone submits only a string of spaces. The string length check
should
eliminate people hitting <ENTER> without typing...
Anyhow, a way to do this (I think; I've tried to avoid JavaScript) is
to split on spaces, then compare the length of the resulting array with
the
initial length. Or you could traverse through the string character by
character and set a flag if a non-space is found...
Let me know if you need more details...
