我有 Angular JS 的实践项目，描述

  1. demoangular.html 页面
  2. Logout.html 页面

demoangular 页面是登录页面，它重定向到 logout.html

但是 logout.html 行为不正常

它在控制台上显示以下错误

最佳答案

您的 CustomersController 声明看起来有误。您已指定:

app.controller('CustomersController', function PostsController($scope, customerFactory) { .. });

应该是:

app.controller('CustomersController', function ($scope, customerFactory) { .. });

我看到的另一个问题如下:

<button type="button" data-ng-click="logout()">logout</button>

没有可调用 logout() 函数的 Controller /作用域上下文。看起来好像您正在通过路由处理此问题，在这种情况下，您应该只有一个注销链接，例如

<a href="/logout">Logout</a>

值得注意的是，这仍然无法解决您的问题。它将加载您的 newController和注销部分。那时你仍然需要一些东西来调用 newController 上的注销函数，例如某种确认。
