自定义规则和错误消息

$(document).ready(function () {
            $("form").validate({
                rules: {
                    Title: { required: true },
                    Img: { required: true }
                },

                messages: {
                    Title: { required: "请输入标题" },
                    Img: { required: "请选择图片" }
                }
            });
        });
