通过视图袋将模型传递给JavaScript

Question

我在序列化中后通过我的类对象，然后将其访问为空白的JavaScript。

我的班级

public class PMICheckListWrapper
        {
            public PMIMachine Machine { get; set; }
            public List<PMICheckListResponse> CheckResponseList { get; set; }
        }

控制器代码：

public ActionResult GetViewEditData(int machineID)
        {
          var result = Json(PMIComputerModel.GetViewEditDetails(machineID), JsonRequestBehavior.AllowGet);
          ViewBag.MachineData = result.Data;
          return View("PMIComputerList");
        }

javaScript我正在访问它。

$(function(){
  if('@ViewBag.MachineData' != null)
        {
         var data = '@ViewBag.MachineData'; 
         alert(data);//this is coming empty
         alert(jQuery.parseJSON(data)); // this is coming null
        }
});

Answer 1

尝试使用

var data = @Html.Raw(@ViewBag.MachineData); 

Answer 2

getVieweditDetails实际上有多确定吗？尝试：

public ActionResult GetViewEditData(int machineID)
    {
      var result = new JsonResult();
      var data = PMIComputerModel.GetViewEditDetails(machineID);
      if(data != null){
            result.Data = data;
      }
      else {
         // give some kind of feedback that there is no result
      }
      ViewBag.MachineData = result;
      return View("PMIComputerList");
    }
