Question

在上图中双击 div（第一张图片）然后查看对话框（第二张图片）两个案例内容都打印了相同数据但结构不同。

控制器

  [HttpPost]
  public ActionResult FirstParialView(long ID)
  {
      //inserted some data into database Here

    List<TimetableDetails> timetableObs =unitofWork.TimetableDetails.ToList();
     return PartialView("DayStructure/_FirstView", timetableObs);
  }   

  [HttpPost]
  public ActionResult SecondParialView(long ID)
  {
    List<TimetableDetails> timetableObs =unitofWork.TimetableDetails.ToList();
     return PartialView("DayStructure/_SecondView", timetableObs);
  }

Ajax调用（此Ajax设计和在对话框中工作）

 @using (Ajax.BeginForm("FirstParialView", "timetable", new { area = "User" },
                        new AjaxOptions { OnSuccess = "ViewMPlan"))
{
      //Inserted Some data using submit button here. and view both parial view
}

的javascript

 function ViewMPlan(response) {
   //print first Parial View
   $('#firstParialView').html(response);
  //for second parial view
    $.ajax({
                url: "/user/timetable/SecondParialView",
                type: "POST",
                dataType: "JSON",
                data: { ID: ID},
                success: function (response) {
               $('#SecondParialView').html(response);
          }
        });
    }

在上面的情况下，我必须分开ajax调用第二个parial视图，实际上它得到相同的数据。

这是否可以仅使用单一呼叫更新两个部分视图，例如仅调用 FirstParialView

你确实可以做到这一点我所做的就是我创建了一个函数，它将部分视图呈现在一个变量中，比如

private string RenderPartialView(string viewName, object model)
        {
            ViewData.Model = model;
            using (System.IO.StringWriter writer = new System.IO.StringWriter())
            {
                ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);
                ViewContext viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, writer);
                viewResult.View.Render(viewContext, writer);

                return writer.GetStringBuilder().ToString();
            }
        }

现在您需要更改您的操作结果，例如

[HttpPost]
public JsonResult AjaxCallFunc(long ID)
{
List<TimetableDetails> timetableObs =unitofWork.TimetableDetails.ToList();
var partialView1 = RenderPartialView("DayStructure/_FirstView", timetableObs);
var partialView2 = RenderPartialView("DayStructure/_SecondView", timetableObs);
return Json(new{View1=partialView1,View2=partialView2 },JsonRequestBehaviour.DenyGet);
}

然后你的控制器

unction ViewMPlan(response) {
   //print first Parial View
   $('#firstParialView').html(response);
  //for second parial view
    $.ajax({
                url: "/user/timetable/AjaxCallFunc",
                type: "POST",
                dataType: "JSON",
                data: { ID: ID},
                success: function (response) {
                $('#FirstPartialView').html(response.View1);
               $('#SecondParialView').html(response.View2);
          }
        });
    }
