jquery - mvc中jquery无法获取json数据

Question

我正在 asp.net MVC 中开发应用程序我的脚本是:

 $(document).ready
     (
       function() {

        var officerid = document.getElementById('officerid').value;
        url = "/TasksToOfficer/Calender/" + officerid;

     var data=   function() 
                {
               $.ajax(
               {
                         type: 'GET',
                         url: url ,
                         dataType: 'json',
                         data: {'start' : start,'end' : end}
                }); 
                }; 


});

我无法从我的 Controller 操作获取数据:

    [HttpGet]
        [AcceptVerbs(HttpVerbs.Get)]

 public JsonResult Calender(Guid id)
        { 
        List<TasksToOfficer> officersTasks = null;
        IList<CalendarDTO> tasksList = new List<CalendarDTO>();
        List<TasksToOfficer> officersTasksRecived = null;
            if (String.Compare(Convert.ToString(Session["Role"]), RolesEnum.Admin.ToString())!=0)
            {
                officersTasksRecived = tasks_to_officer_management.GetTasksToOfficers(id);
                foreach (TasksToOfficer tt in officersTasksRecived)
                {
                    DateTime dt = Convert.ToDateTime(tt.Date);
                    tasksList.Add(new CalendarDTO
                    {
                    id=tt.Id,
                    title =tt.Description,
                    start = ToUnixTimespan(dt),
                    end = ToUnixTimespan(dt),
                    url =""}
                    );
                }
            }
          else
                if (String.Compare(Convert.ToString(Session["Role"]), RolesEnum.Officer.ToString()) != 0)
                {
                    officersTasksRecived = tasks_to_officer_management.GetTasksToOfficers(id);
                    foreach (TasksToOfficer tt in officersTasksRecived)
                    {
                        DateTime dt = Convert.ToDateTime(tt.Date);
                        tasksList.Add(new CalendarDTO
                        {
                            id = tt.Id,
                            title = tt.Description,
                            start = ToUnixTimespan(dt),
                            end = ToUnixTimespan(dt),
                            url = ""
                        }
                        );
                    }
                }
            JsonResult resultToView = Json(tasksList);
            return Json(resultToView,JsonRequestBehavior.AllowGet);
        }

应该是什么错误？事实上，我正在尝试将事件附加到完全日历控制上。我正在收集记录并在我的操作中构建 JSon 数据。但无法在我的日历上显示。我必须做什么？

Answer 1

这里只是一个猜测，但我认为问题是你正在 JSON 序列化 JsonResult 而不是 IList<CalendarDTO> 。而不是这样做:

  JsonResult resultToView = Json(tasksList);
  return Json(resultToView,JsonRequestBehavior.AllowGet);

为什么不试试这个呢？

  return Json(tasksList,JsonRequestBehavior.AllowGet);
