   function  CommentBegin()   {  
           alter("开始");
                   $("#CommentForm   input").attr ( "readonly" ,   true ) ;  
                   $("#CommentSubmit") . attr ( " disabled " ,   "disabled" ) ;  
                  $("#CommentMsg").html ("" ) ;  
                    alter("aa");
          }   
    function   CommentSuccess(e)   
    {  
         alter("成功");
                 
     }   
             
    
</script>  控制器:
 [HttpPost]  
        public   JsonResult   AddDept ( aa.Models.DeptTbl d)  
        {
            //先测试,暂时OK
            return Json(new { Success = true, Message = " 添加部门信息OK！ " },    JsonRequestBehavior.DenyGet);  
        }
