搜索 formnovalidate

然后改成这种，也就是if中间注释

                    // allow suppressing validation by adding the html5 formnovalidate attribute to the submit button
                    if ($(event.target).attr("formnovalidate") !== undefined) {
                        //validator.cancelSubmit = true;
                    }

搜索elements 大概500行左右

  elements: function () {
                var validator = this,
                    rulesCache = {};

                // select all valid inputs inside the form (no submit or reset buttons)
                return $(this.currentForm)
                .find("input, select, textarea")
                .not(":submit, :reset, :image,:button, [disabled]")
                .not(this.settings.ignore)
                .filter(function () {
                    if (!this.name && validator.settings.debug && window.console) {
                        console.error("%o has no name assigned", this);
                    }

                    // select only the first element for each name, and only those with rules specified
                    if (this.name in rulesCache || !validator.objectLength($(this).rules())) {
                        return false;
                    }

                    rulesCache[this.name] = true;
                    return true;
                });
            },

改成这种，然后运行会JS报错，然后调试会提示原生的js getattribute不存在啥的，把那里用替换成
