如何在控制器或模型或视图（主体渲染之前）MVC中获取sessionStorage（客户端）值

问题描述 投票：0回答：2
  1. 我想做的是第一次加载应用程序时，我会将菜单存储在客户端sessionStorage中，下一次从sessionStorage中加载任何页面时，都会获取菜单
  2. 我的网站流程是LoginPage>仪表板页面
  3. 仪表板页面呈现为index.csHtml并向读者使用_Layout.csHtml部分视图
  4. 我已在客户端成功存储sessionStorage值，但无法在_Layout.csHtml页面中获得此保存值。
  5. 在_Layout.csHtml正文部分，此代码使用@{Html.RenderAction("RenderTopMenu", "Common");}，我需要在此RenderAction中传递sessionStorage值例如：@{Html.RenderAction("RenderTopMenu", "Common", new {model=sessionStorage});}
PAGE - Index.csHtml 

@{
   ViewBag.Title = "Welcome To " + SessionManagement.CompanyName;
   Layout = (ViewBag.isPartialView) ? null : "~/Views/Shared/_Layout.cshtml";
}

PAGE - _Layout.cshtml

<!DOCTYPE html>
<html>
<head>
</head>
<body class="pageContent">

   @{Html.RenderAction("RenderTopMenu", "Common");}
</body>

PAGE - Controller
public ActionResult RenderTopMenu(DashboardViewModel AdminMenus)
       {
           DashboardViewModel Dashboardmodel = new DashboardViewModel();
           Dashboardmodel = DashboardModel.GetTopMenu(Dashboardmodel);
}

PAGE - Model

public List<AdminMenus> GetMenuListFromCache(int AccountMode, DashboardViewModel Dashboardmodel)
       {
List<AdminMenus> AdminMenusList = sessionStorage.getitem("Menu") as List<AdminMenus>;


                   if (AdminMenusList == null) //not in cache
                   {
                       AdminMenuParamsModel menus = new AdminMenuParamsModel()
                       {
                           CompanyID = SessionManagement.IntCompanyID,
                           MenuID = AccountMode
                       };

                       AdminMenusList = new DashboardBLL(SessionManagement.DevPasswordConnectionString).ProcessGetMenus(menus);
                       AdminMenusList = DashboardModel.SetMenuName(AdminMenusList);
                       sessionStorage.setitem("Menu") = AdminMenusList;
                   }
                   return AdminMenusList;
}

NOTE: In a model for only explanation purpose I put sessionStorage.getitem but really I can not use this.

在此行@ {Html.RenderAction（“ RenderTopMenu”，“ Common”，新的{model = sessionStorage}）;}您只需要使用

@@ Html.RenderAction（“ RenderTopMenu”，“ Common”，新的{model = sessionStorage.Menu}）;}要么@ {Html.RenderAction（“ RenderTopMenu”，“ Common”，新{model = sessionStorage.getitem（“ Menu”）}）;}理想情况下应该可以工作。

您无法从razor访问javascript值，我建议您使用jquery或javascript编码菜单，也可以将菜单对象保存在服务器端的会话中并将其传递到查看包中，然后使用剃须刀。
