Accessing the submitted values on the form .submit event

Accessing the submitted values on the form .submit event

Hi, I have a form which has a few submit buttons, all named SubmitButton so I can pass the clicked button's value through to the submission processor and then act according to which button is pressed.  However on the jquery form submit even, I also want to check certain things before I fire the submission off.  As the button isn't a "conventional" input I can't check the document object to see which one was clicked, so I need to check the form contents that are about to be submitted, can I do this from the submission event or will I have to bind to each button individually?
