As I can't comment on the accepted answer, I bring here a modified version that should take into account elements that are outside the form (ie: attached to the form using the form attribute). This is for modern browser: http://caniuse.com/#feat=form-attribute . The closest('form') is used as a fallback for unsupported form attribute

$(document).on('click', '[type=submit]', function() {
    var form = $(this).prop('form') || $(this).closest('form')[0];
    $(form.elements).filter('[type=submit]').removeAttr('clicked')
    $(this).attr('clicked', true);
});

$('form').on('submit', function() {
    var submitter = $(this.elements).filter('[clicked]');
})
