EasyUI 两个日期比较

 $.extend($.fn.validatebox.defaults.rules, {
        /*必须和某个字段相等*/
        equalTo: { validator: function (value, param) { return $(param[0]).val() == value; }, message: ‘字段不匹配‘ }
       });

密码： <input id="password" name="password" validType="length[4,32]" class="easyui-validatebox" required="true" type="password" value=""/><br/>
          确认密码：<input type="password" name="repassword" id="repassword" required="true" class="easyui-validatebox"  validType="equalTo[‘#password‘]" invalidMessage="两次输入密码不匹配"/>

$.extend($.fn.validatebox.defaults.rules, {
        /* 两个日期进行比较 */

            validator : function(value,param){
