登录Angularjs MVC项目VS15后下拉列表不起作用

我正在Visual Studio 2015默认MVC项目中从事AngularJS项目

我已使用引导模板对此默认项目进行了更改

一切正常，但登录后，下拉菜单不会显示my _LoginPartial视图中列出的两个内容。在登录之前，此下拉列表可以正常工作，显示基于If-else条件的_LoginPartail视图的内容

下面是登录部分视图的代码

@using Microsoft.AspNet.Identity
    
    @if (ViewBag.login == true)
    {
        using (Html.BeginForm("LogOff", "Account", FormMethod.Post, new { id = "logoutForm", @class = "navbar-right" }))
        {
            
            <div class="Logoutapp" ng-app="Logoutapp" ng-controller="AccountController">
    
                <ul class="dropdown-menu">
                    <li>
                        @Html.ActionLink("Hello " + @Session["User"] + " !", "Index", "Manage", routeValues: null, htmlAttributes: new { title = "Manage" })
                    </li>
                    <li>
                        <a ng-click="logout()">{{btntext}}</a>
                    </li>
                </ul>
                <script src="~/Scripts/angular.js"></script>
                <script src="~/Scripts/Angular Scripts/LoginJS/Logout.js"></script>
                <script src="~/js/bootstrap.js"></script>
            </div>
    
        }
    }
    else
    {
        <ul class="dropdown-menu">
            <li>@Html.ActionLink("Register", "Register", "Account", routeValues: null, htmlAttributes: new { id = "registerLink" })</li>
            <li>@Html.ActionLink("Log in", "Login", "Account", routeValues: null, htmlAttributes: new { id = "loginLink" })</li>
        </ul>
    }

@使用Microsoft.AspNet.Identity
@如果（ViewBag.login==true）
{
使用（Html.BeginForm（“注销”、“帐户”、FormMethod.Post、新的{id=“logoutForm”、@class=“navbar right”}））
{


@ActionLink（“Hello”+@Session[“User”]+”！，“Index”，“Manage”，routeValue:null，htmlAttributes:new{title=“Manage”}）





@*
*@
@Html.Partial（“_LoginPartial”）
@*
*@









@ActionLink（“帮助”、“帮助”、“主页”）

登录前下拉列表
