jqGrid增加时--判断开始日期与结束日期(实例解析)

代码如下:

$("#btnAddSaveTestSubject").click(function () {
        //增加时的验证，保存
        jQuery.validator.addMethod("admissionBatch", function (value, element) {
            return this.optional(element) || value != 0;

        jQuery.validator.addMethod("educationLevel", function (value, element) {
            return this.optional(element) || value != 0;
        }, "请选择学历层次");
        jQuery.validator.addMethod("professionalProperty", function (value, element) {
            return this.optional(element) || value != 0;
        }, "请选择专业性质");
