$("form").validate();
    $(function () {
                $.each($.validator.methods, function (key, value) {
                $.validator.methods[key] = function () {
                var el = $(arguments[1]);
                if (el.is('[placeholder]') && arguments[0] == el.attr('placeholder'))
                    arguments[0] = '';
                    return value.apply(this, arguments);
                    };
                 });
      });
