Haven't delved into AHAH yet, this might force the issue.
Using an easy (=less typing) example. A credit card form. When the
credit card type is selected from a select, the selection needs to
fire a javascript function that will disable fields that don't apply
to that card type (such as CVV).
Normally, I would have an onchange event for the select, and noticed
that in the form api, while there is an attribute section to add
miscellaneous attributes, the doc doesn't mention events as examples.
And if putting an event there is legitimate, there isn't a mention of
how to include the responding js function in the form.
If AHAH is the way I'm supposed to handle this, I'd appreciate being
pointed to a good similar example, because I'm a bit unclear from the
AHAH entries in the form reference docs, for example, how to relate
the myhandler/js entry to a physical location of the function, and how
the function gets there.
You wouldn't use AHAH. CTools as a tool called 'dependent' that will
help you do this kind of behavior without having to write any javascript.
