Actually, if the same form is used more than once on a page, you can almost guarantee that it will *not* have the same name. Take a look at the comments in "form_clean_id()" concerning its effects on jQuery. I think adding a class might make this more difficult, unless that code is fully aware of multiple instances of a form on a page.

However, you cannot therefore guarantee that the form element will
always have the same ID.

Usually I'd add a class to the item I want to add the behaviour to (in
form alter or theme function), and then attach the javascript using
the Drupal.behaviors technique.
