RE: [cinjug-users] jsp form question

["Robert Casto" <robert@xxxxxxxxxxxxx>]

I have noticed though that the new IE 6.0+ has problems with doing POST and
that you need those lines to ensure the submit is done correctly. Otherwise
the user things the submit happened, but the browser never sends it to the
server. It will do a GET method instead which is not what is wanted.

Actually you don't need the else part there at all.  If you return a false
from a function in an onSubmit or onClick the action gets cancelled.  So all
you need to do is change your  function to look like:

                 if(thisForm.comp.value == '')
                 {
                         alert('Company name is required.');
                         thisForm.comp.focus();
                         return false;
                 }
                  ...
                  return true;

Also make sure you do the same validation on the server side.  Never trust
the
client to send you good data.
