I might suggest "Undo last action," but that's up to you (since you
have committed the last transaction at that point, you aren't
cancelling it, you are committing a new action that effectively undoes
it). "Cancel" at the UI level I associate with exiting a form without
taking _any_ action.
Anyway, if you only have one submit button per form, or if you don't
mind disabling all of them, then you can indeed attach the events to
the form's Submit and later grab the child submits:
document.id('myform').getElements('input[type=submit]').each(function(itm,idx){
// disable the itm
})
-- using the Moo way to get all the descendent elements -- and disable
each one.
But if you have more than one submit button per form, and you only
want to disable the one the user clicked, then you attach the events
to each button's Click, as we have gone over earlier.
