onSubmit vs. <input type="submit"

Hi,

I'm converting HTML submit buttons over to three part gif images for a client
(I don't ask, I just duz) and I cannot figure out one thing.

Client had <.input id="mediaMaint" name="mediaMaint" type=submit 
value="Special String" tabindex="3">

They're doing some back end template stuff, and I'm obfuscating to protect 
the client.

There's two input buttons on this page and each has a different name.

How can I use submit() in a similar fashion?  How do I pass the name/id as 
to which "button" was clicked?
Should i have a hidden variable be written out by javascript onclick before 
it calls the submit() method?

Thanks.  I'm sure this must be common, but i could find nothing after a 
whole day of searching hwg archives
and google.
