[Zope] HowTo? onChange assign value to dtml-var

[Shaw, Mark]

Thanks everyone.  My solution was to use a plain old javascript variable and
not a DTML variable.

onChange="(first_name = this.value)" where first_name is a global javascript
variable.

Sorry, but, the DTML is long resolved and done before the web page ever
gets to your browser, so you can't assign anything to DTML from a form
action *while still on that page*.

This isn't a Zope problem; its the whole fundamental client/server web
thang.

The onChange method could load a new page, or refresh the current page,
passing the new name as it did so.
