[Javascript] required entry field

Sat Mar 29 11:26:45 CST 2003

Maybe you have a new-extra-strength browser, but mine gets cranky when you 
start sticking buttons, inputs, whatever on the page without a form wrapper.

Yes, it would be nice to dispense entirely with the need for forms when all
you want is a local collecting point for data (which can then be cached as
cookies on the remote machine) -- but most of the dynamic variables in
JavaScript don't work that way.  

However, not to worry -- if you want to neuter your form just slap an action
declaration in place in your form header which reads as 

  <form name='myForm' action="javascript:void(null)" ...

and you have a form that does nothing but collect data on the client window.
