Prevent Duplicate Form Submissions with jQuery

gistfile1.js

jQuery(function() {
  $("form").submit(function() {
		// submit more than once return false
		$(this).submit(function() {
			return false;
		});
		// submit once return true
		return true;
	});
});

/* or */

jQuery('form').submit(function(){
$(this).find(':submit').attr( 'disabled','disabled' );
});

Thanks! That's really helpful.
