jquery - 从 Controller 调用Viewbag数据来查看

Question

Controller:-

[HttpPost]
        public ActionResult EmailScheduler()
        {
            long lCustDesignID = 1;
                int countProduct = gateWay.TotalCountOfCustomers(lCustDesignID);
                ViewBag.ItemCount = countProduct;

            return Json(JsonRequestBehavior.AllowGet);
        }

View:-

<h4>Number Of Records - <span>@ViewBag.ItemCount</span> </h4>

This controller is called on button click.

From Controller how to get value to View in viewbag.

.

Answer 1

如果EmailScheduler是ajax调用，那么你不能像你尝试过的那样使用ViewBag。

您需要像下面这样修改您的代码。

Controller

[HttpPost]
public ActionResult EmailScheduler()
{
   long lCustDesignID = 1;
   int countProduct = gateWay.TotalCountOfCustomers(lCustDesignID);                    
   return Json(countProduct,JsonRequestBehavior.AllowGet);
}

HTML

<h4>Number Of Records - <span id="spnCount"></span> </h4>

Ajax

$.ajax({
   //....
   success: function(data){
      $('#spnCount').text(data);
   }
})
