用于选项卡的AngularJS控制器

Question

我的页面中有三个选项卡.我正在使用tabset并tab根据Angular Bootstrap Docs.

我设置一个控制器,用于在<div>其具有tabset如

<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>

相应的页面是

但是,当我尝试为我的第二个标签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,我不能再单击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) {

});

我认为至少有三种方法可以组织您的控制器代码:

1. 一切都在一个 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.

请看下面的演示或jsfiddle的演示.

这是ui-bootstrap添加了上述要点的示例代码.

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';
        }
    }
}
