我正在通过开发一个项目来学习 Angularjs 和 Nodejs。我已经按照本教程组织了我的文件夹结构和路由配置。

问题： 我添加了一个名为 isActive 的方法来根据选项卡单击更新 ng-class。但是当我单击选项卡时，它没有调用 isActive 方法。

我的猜测是，我在 appRoutes.js 中做错了，但不知道如何解决这个问题。我能够到达 MainController 但不能到达其中的方法。

我还有一个问题，当我进入应用程序或单击主页选项卡或单击应用程序标题时，我需要激活主页选项卡。

下面是html和js代码。

可能是您忘记添加。否则

        .when('/', {
            templateUrl: 'views/partials/home.html',
            controller: 'MainController'
        })

        .when('/home', {
            templateUrl: 'views/partials/home.html',
            controller: 'MainController'    
        })
        .otherwise({
                redirectTo: '/'
            });

更新：试试这个 - 在navigation_main.html

 <li ng-class="{'active' : path}" >
    <a href="/imageoperations" id="nav_img" ng-click="itemClicked('/imageoperations')">Image Operation's</a>
  </li>

MainCtrl.js

angular.module('MainCtrl', []).controller('MainController', function($scope) {
        console.log('Main Controller');

        $scope.itemClicked= function(destination) {
                      $scope.path = destination;
        }

    });

您的 navigation_main.html 超出了控制器范围。这是主要原因。尝试像这样为您的导航创建单独的控制器 

.controller('NavCtrl', function($scope) {
    isActive = function(destination) { /*...*/ }
}

将其放入文件js/nav.js并添加到您的 html

<script type="text/javascript" src="js/nav.js"></script>

然后将此控制器添加到您的 navigation_main.html 代码中 

<div ng-controller="NavCtrl">

关于未达到 isActive 方法的问题：
尝试重新组织：

    <script type="text/javascript" src="js/controllers/MainCtrl.js">         </script>
    <script type="text/javascript" src="js/controllers/HomeCtrl.js"></script>
    <script type="text/javascript" src="js/appRoutes.js"></script>
    <script type="text/javascript" src="js/app.js"></script>

进入：

    <script type="text/javascript" src="js/app.js"></script>
    <script type="text/javascript" src="js/appRoutes.js"></script>
    <script type="text/javascript" src="js/controllers/MainCtrl.js"></script>
    <script type="text/javascript" src="js/controllers/HomeCtrl.js"></script>

尝试在 a 标签中添加 ng-click=isActive('/home')。

<li ng-class="{active : activeClass == 'home'}" id="nav_home">
    <a href="/home" ng-click=isActive('/home')>Home</a>
</li>

在你的 MainCtrl 添加这一行，

$scope.activeClass = '';
$scope.isActive = function(destination) {
    $scope.activeClass = destination;
}

您可以尝试使用 angular ui-router 进行路由，并在状态处于活动状态时添加活动类。您只需要添加 ui-sref-active="YourActiveClassHere"。Angular UI-路由器

尝试改变这个顺序，

    <script type="text/javascript" src="js/controllers/MainCtrl.js"></script>
    <script type="text/javascript" src="js/controllers/HomeCtrl.js"></script>
    <script type="text/javascript" src="js/appRoutes.js"></script>
    <script type="text/javascript" src="js/app.js"></script>

对此，

    <script type="text/javascript" src="js/app.js"></script>
    <script type="text/javascript" src="js/appRoutes.js"></script>
    <script type="text/javascript" src="js/controllers/MainCtrl.js"></script>
    <script type="text/javascript" src="js/controllers/HomeCtrl.js"></script>
