jQuery addClass（＆＃39; error＆＃39;）到＆＃34; jQuery Validation Plugin v1.12＆＃34;

Question

这是jQuery的一部分＆＃34;验证＆＃34;插件，我试图改变以获得上面的屏幕截图结果：

＆＃13;

＆＃13;

attributeRules: function( element ) {
        var rules = {},
                $element = $(element),
                type = element.getAttribute("type"),
                method, value;

        for (method in $.validator.methods) {

// support for <input required> in both html5 and older browsers
                if ( method === "required" ) {
                        value = element.getAttribute(method);
// Some browsers return an empty string for the required attribute
// and non-HTML5 browsers might have required="" markup
            if ( value === "" ) {
                 value = true;
         $("#alertBox").css("display", "block");
            }
// force non-HTML5 browsers to return bool
                        value = !!value;
                } else {
                        value = $element.attr(method);
                }

// convert the value to a number for number inputs, and for text for backwards compability
// allows type="date" and others to be compared as strings
                if ( /min|max/.test( method ) && ( type === null || /number|range|text/.test( type ) ) ) {
                        value = Number(value);
                }

                if ( value || value === 0 ) {
                        rules[method] = value;
                } else if ( type === method && type !== "range" ) {
// exception: the jquery validate 'range' method
// does not test for the html5 'range' type
                        rules[method] = true;
                }
        }

// maxlength may be returned as -1, 2147483647 (IE) and 524288 (safari) for text inputs
        if ( rules.maxlength && /-1|2147483647|524288/.test(rules.maxlength) ) {
                delete rules.maxlength;
        }

        return rules;
},

Answer 1

将此添加到jquery：

$("#myForm").validate({
            highlight: function (element, errorClass, validClass) {
                var index = $(element).index();
                var question = $(element).closest('tr').find('.ro-question');
                question.removeClass(validClass).addClass(errorClass);
                console.log('aaa');
                var question = $(element).closest('thead').find('.topAlign');
                question.removeClass(validClass).addClass(errorClass);
            },
            unhighlight: function (element, errorClass, validClass) {
                var index = $(element).index();
                var question = $(element).closest('tr').find('.ro-question');
                question.removeClass(errorClass).addClass(validClass);
                var question = $(element).closest('thead').find('.topAlign');
                question.removeClass(errorClass).addClass(validClass);
            }

})
