Question

我正在通过开发项目来学习Angularjs和Nodejs。我已经遵循了这个tutorial并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的方法来更新基于选项卡点击的ng-class。但是当我点击标签时，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。我能够访问MainController，但不能访问其中的方法。

我还有另外一个问题，我需要在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激活“主页”选项卡。

下面是html和js代码。

的index.html

navigation_main.html

<div>
  <nav class="navbar navbar-inverse">
    <ul class="nav navbar-nav">

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

      <li><a href="#" style="margin-right: 20px; color: white;">Login/Register</a></li>

</div>

header.html中

<div>
  <header id="header" style="margin-left: 50px;">
      <a href="/" style="text-decoration: none; color: black;">
        <strong>eTools Store</strong>
      </a>

appRoutes.js

angular.module('appRoutes', []).config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {
    $routeProvider

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

        .when('/home', {

            controller: 'MainController'    
        });

        $locationProvider.html5Mode(true);
}]);

app.js

    angular.module('etsApp', ['ngRoute', 'appRoutes', 'HomeCtrl', 'MainCtrl']);

MainCtrl.js

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

        $scope.isActive = function(destination) {
            console.log($location.path());
            return destination === $location.path();
        }

    });

Answer 1

关于未达到的问题isActive方法：
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>

成：

    <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>

Answer 2

可能你忘了添加.otherwise

        .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

中

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

<强> MainCtrl.js

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

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

    });

Answer 3

您的navigation_main.html不在控制器范围内。这是主要原因。尝试为此导航创建单独的控制器

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

将其放入档案 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

<div ng-controller="NavCtrl">

Answer 4

您可以尝试使用角度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-Router

尝试更改此顺序，

    <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>

Answer 5

尝试在标签中添加ng-click = isActive（＆＃39; / home＆＃39;）。

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

在您的MainCtrl中添加此行，

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