想請問這個controller該如何寫

  $(document).ready(function () {
        var saveResult = '@ViewBag.SaveResult';
        if (saveResult.toLowerCase() == 'true') {
            var saveResultMessage = '@ViewBag.SaveResultMessage';
            if (saveResultMessage == '') saveResultMessage = '儲存成功';
            $bui.alertOK(saveResultMessage);   
        }
        else if (saveResult.toLowerCase() == 'false') {
            var saveResultMessage = '@ViewBag.SaveResultMessage';
            if (saveResultMessage == '') saveResultMessage = '儲存失敗';
            $bui.alertError(saveResultMessage);

        }
    });
    
         

這是我的一段Jquery,主要是給下面這種controller使用

 public ActionResult AddOrUpdate(HomeVisitViewModel model)
        {
            if(!ModelState.IsValid)
            {
                ViewBag.SaveResult = false;
                return View("HomeVisitEdit", model);
            }
            PD_HOME_VISIT pdhomevisit = new PD_HOME_VISIT();
            HomeVisitService hvsrvc = new HomeVisitService();

            bool saveResult = false;
            bool isAdd = false;
         
            //如果GUID空值或null就進行新增動作
            if (String.IsNullOrWhiteSpace(model.GUID) || new Guid(model.GUID) == Guid.Empty)
            {
                isAdd = true;          

            }
            if (model.NUTRITIONAL_SUPPLEMENT == "1")
            {
                model.NUTRITIONAL_SUPPLEMENT_CODE = string.Join(",", model.NUTRITIONAL_SUPPLEMENT_CODES.ToArray());
            }
            if (model.HOME_CARE_CODES != null) model.HOME_CARE_CODE = string.Join(",", model.HOME_CARE_CODES.ToArray());
            if (model.LIQUID_EXCHANGE_CODES != null) model.LIQUID_EXCHANGE_CODE = string.Join(",", model.LIQUID_EXCHANGE_CODES.ToArray());
            if (model.LE_PREPARE_CODES != null) model.LE_PREPARE_CODE = string.Join(",", model.LE_PREPARE_CODES.ToArray());
            if (model.LE_LIQUID_EXCHANGE_CODES != null) model.LE_LIQUID_EXCHANGE_CODE = string.Join(",", model.LE_LIQUID_EXCHANGE_CODES.ToArray());
            if (model.END_LE_LIQUID_EXCHANGE_CODES != null) model.END_LE_LIQUID_EXCHANGE_CODE = string.Join(",", model.END_LE_LIQUID_EXCHANGE_CODES.ToArray());
            if (model.PD_RECORD_CODES != null) model.PD_RECORD_CODE = string.Join(",", model.PD_RECORD_CODES.ToArray());
            if (model.CATHETER_OUTLET_CODES != null) model.CATHETER_OUTLET_CODE = string.Join(",", model.CATHETER_OUTLET_CODES.ToArray());
            if (model.DS_STOIRAGE_CODES != null) model.DS_STOIRAGE_CODE = string.Join(",", model.DS_STOIRAGE_CODES.ToArray());
            if (model.ORDER_COMOLIANCE_CODES != null) model.ORDER_COMOLIANCE_CODE = string.Join(",", model.ORDER_COMOLIANCE_CODES.ToArray());

            model.VISITDATE = DateHelper.ToDate(model.VisitDateString);
            model.HD_DATE = DateHelper.ToDate(model.HD_DateString);
            model.PD_DATE = DateHelper.ToDate(model.PD_DateString);
            model.FIRST_PD_PLACE_DATE = DateHelper.ToDate(model.First_PD_Place_Date_String);
            model.PERITONITIS_DATE = DateHelper.ToDate(model.Peritionitis_Date_String);
            model.EXIT_SITE_INFECTION_DATE = DateHelper.ToDate(model.Exit_Site_Infection_String);

            pdhomevisit = model.ToHomeVisit(SessionUserInfo().UserID);
            if (isAdd)
            {
                saveResult = hvsrvc.AddHomeVisit(pdhomevisit);
            }
            else
            {
                saveResult = hvsrvc.UpdateHomeVisit(pdhomevisit);
            }
          
            ViewBag.SaveResult = saveResult;
      
          
            HomeVisitViewModel newmhomevisit = GetHomeViewModel(pdhomevisit.GUID.ToString());
        
            newmhomevisit.Assess();
            return View("HomeVisitEdit", newmhomevisit);
        }

只要儲存成功,就會顯示儲存成功這個訊息,反之失敗也是,現在我想做一個新的訊息

是只要我HomeVisitViewModel裡的這個欄位

  public string PRICE { get; set; }

只要新增或編輯時沒有值就會顯示請計價這個訊息,想請問這個controller我該如何寫?

目前我只暫時寫好前端

   var priceResult = '@ViewBag.priceResult';

        if (saveResult.toLowerCase() == 'false') {
            var priceResultMessage = '@ViewBag. priceResultMessage';
            if (priceResultMessage == '') priceResultMessage = '請計價';
            $bui.alertError(priceResultMessage);
        }

如果原本那串可以正常運作,
先把原本那串搞懂你就會寫了.
