javascript - 用于选项卡的 AngularJS 控制器

Question

我的页面中有三个标签。我正在使用tabset并tab根据Angular Bootstrap Docs。

我设置了一个控制器，<div>它具有tabsetas

<div ng-controller="Tabs" class="panel panel-default" id="tabs-panel"> 
  <tabset  class="panel-body">
    <tab heading="Tab 1"> </tab>
    <tab heading="Tab 2"> </tab>
    <tab heading="Tab 3"> </tab>
  </tabset>
</div>

对应的页面是

但是，当我尝试为我的第二个选项卡添加另一个控制器时

<div ng-controller="Tabs" class="panel panel-default" id="tabs-panel"> 
  <tabset  class="panel-body">
    <tab heading="Tab 1"> </tab>
    <tab heading="Tab 2" ng-controller="Tab2> </tab>
    <tab heading="Tab 3"> </tab>
  </tabset>
</div>

我现在发现标题没有显示，我不能再点击 Tab2。

这是为什么？如何恢复相同的功能？

这是在现有控制器中添加另一个控制器的正确方法吗？

我的app.js：

var myApp = angular.module('myApp',['ui.bootstrap']);

myApp.controller('Tabs', function ($scope) {

});


myApp.controller('Tab2', function ($scope) {

});

我认为至少可以通过三种方式组织控制器代码：

1. 一切合二为一TabController
2. 每个选项卡的自定义指令
3. 将选项卡逻辑添加到选项卡回调函数。

请查看下面的演示或jsfiddle此处的演示。

这是ui-bootstrap添加了上述几点的示例代码。

angular.module('demoApp', ['ui.bootstrap'])
    .controller('TabsDemoCtrl', TabsController)
    .directive('sepecialTab', SpecialTab);

function TabsController($scope, $window) {
    $scope.tabs = [{
        title: 'Dynamic Title 1',
        content: 'Dynamic content 1'
    }, {
        title: 'Dynamic Title 2',
        content: 'Dynamic content 2',
        disabled: true
    }];

    $scope.alertMe = function () {
        setTimeout(function () {
            $window.alert('You\'ve selected the alert tab!');
        });
    };

    $scope.thirdTabCallback = function () {
        $scope.test = 'I\'m the third tab callback';

        $scope.clickme = function () {
            $window.alert('third tab only function');
        };
    };
}

function SpecialTab() {
    return {
        restrict: 'A',
        controller: function ($scope) {
            console.log('Special tab ctrl, runs on start.');
            $scope.hello = 'hello from special tab controller';
        }
    }
}

    </tabset>
</div>

这里有一个在选项卡中使用的自定义指令，因此我可以为每个选项卡使用自定义控制器。

angular.module('myModule', ['ui.bootstrap'])
  .directive('tabController', function() {
    return {
      restrict: 'A',
      controller: '@',
      name: 'tabController',
    }
  })
  .controller('MyCustomController', function() {
    var vm = this;
    vm.title = "Hey, I am The first controller";
  })
  .controller('MyCustomController2', function() {
    var vm = this;
    vm.title = "Hey, I am the second controller!";
  });

<div ng-app="myModule">


  <uib-tabset type="tabs">
    <uib-tab tab-controller="MyCustomController as ctrl">
      <uib-tab-heading>
        <span ng-bind="ctrl.title"></span>
      </uib-tab-heading>
      <p ng-bind="ctrl.title"></p>
    </uib-tab>
    <uib-tab tab-controller="MyCustomController2 as ctrl2">
      <uib-tab-heading>
        <span ng-bind="ctrl2.title"></span>
      </uib-tab-heading>
      <p ng-bind="ctrl2.title"></p>
    </uib-tab>

  </uib-tabset>

</div>
