[development] Drupal way of doing onchange

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
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.
