cgiemail - formquestion

I made a form that is working... Now the client wants
the form to self-update the content of the fields as
the user fills out the form. For example, if they pick
2 t-shirts in a certain field (that cost 10 each),
then in the subtotals field for t-shirts, it already
shows up the value for 2 t-shirts, $20...

Is this possible with a form in a html that submits
the info with cgiemail? Or would it better be done
with dhtml? Do you know where I can get a code that
would make this happen?

Thanks!
Patricia

I would choose DHTML or JavaScript - which are things that happen on
the client.

Otherwise you wouod have to set each field as a submit to get the
server side CGI to process it. It would take forever depending upon
the complexity of the form.

However, there are perl modules which allow you to write Client-side JS code:

Goto search.cpan.org and see what modules are available.

DHTML being code for "JavaScript + DOM + HTML" ... usually.

The problem with this is that you can't know if it will work - it
depends on the client. It is also easy for the client to forge. So
while it can be used to give information to the user, it is essential
that you do not depend on any data generated from JavaScript to either
exist or be accurate.
