在ASP.NET MVC3中使用ajax更改ViewBag

ViewBag、ViewData和TempData在我第一次调用视图时只调用一次

如果我不刷新页面，就永远不会更改

因为我想使用Ajax进行更改（每10秒，我称之为Ajax）

请参见下面的代码

===========================在控制器中=======================

 public ActionResult OriginView()
 {

      ViewBag.IntData = 1;

      return View();

 }


 public JsonResult ChangeViewBag(int CurrentInterval)
 {

      ViewBag.IntData = CurrentInterval;

      return Json(new{IntData=CurrentInterval},JsonRequestBehavior.AllowGet);

 }

 var CurrentInterval = 2

 $.getJSON('@Url.Action("ChangeViewBag","Controller")', {CurrentInterval:CurrentInterval},function(response){

    @*CurrentInterval++ every ten sec, I want to use CHANGED ViewBag here!*@

    alert(@ViewBag.IntData) @*but **Result is still 1**, unchanged!*@

    alert(response.IntData) @*ofcourse I can use it in this way. *@

    @* but I should use below ASP.NET CODE

    @{
       string TimeData = DateTime.Now.AddSeconds(**ViewBag.IntData**).ToString();
    }

    ***The position is impossible to javascript variable.*** right?*@
 });

=====================在OriginView.cshtml中=======================

 public ActionResult OriginView()
 {

      ViewBag.IntData = 1;

      return View();

 }


 public JsonResult ChangeViewBag(int CurrentInterval)
 {

      ViewBag.IntData = CurrentInterval;

      return Json(new{IntData=CurrentInterval},JsonRequestBehavior.AllowGet);

 }

 var CurrentInterval = 2

 $.getJSON('@Url.Action("ChangeViewBag","Controller")', {CurrentInterval:CurrentInterval},function(response){

    @*CurrentInterval++ every ten sec, I want to use CHANGED ViewBag here!*@

    alert(@ViewBag.IntData) @*but **Result is still 1**, unchanged!*@

    alert(response.IntData) @*ofcourse I can use it in this way. *@

    @* but I should use below ASP.NET CODE

    @{
       string TimeData = DateTime.Now.AddSeconds(**ViewBag.IntData**).ToString();
    }

    ***The position is impossible to javascript variable.*** right?*@
 });

.Net天才请！！！

如果不可能，有什么想法吗？

ViewData

/

ViewBag

（这是一个围绕

ViewData

的包装器）用于将控制器之间的数据传递到视图，并且在每个请求中都会创建这些数据，无论是AJAX还是普通的。它们不能帮助您保持状态：（

代码正按照您的要求执行。也许您可以花更多的时间讲述您想做什么？您似乎在javascript中非常依赖ViewBag，这就像期待一艘美国战舰参与我在堪萨斯州制作花生酱沙一样。明白了！感谢您的参与！！！a但是，你没有叙述。我很困惑。
