[jQuery] (validate) submit using submithandler : how to post value of submit button


I'm using jquery validation to validate and submit all my forms.
The submitHandler of jquery validation uses jquery form plugin to
submit the form using $(form).ajaxSubmit()
Without validation, you can use $(form).ajaxForm(...) to submit your
form using ajax, and this will also send the value of the button which
caused the submit.
With validation, I have to use ajaxSubmit, instead of ajaxForm, but
ajaxSubmit can not automatically add the value of the submit button to
the POST values.
Is there a generic way, to find out in the submitHandler of jquery
validation, which button was pressed that caused the submit ?
