# ionic 切换开关操作 以下实例中，通过切换不同开关 checked 显示不同的值，true 为打开，false 为关闭。 ### HTML 代码 ``` <ion-header-bar class="bar-positive"> <h1 class="title">开关切换</h1> </ion-header-bar> <ion-content> <div class="list"> <div class="item item-divider"> Settings </div> <ion-toggle ng-repeat="item in settingsList" ng-model="item.checked" ng-checked="item.checked"> {{ item.text }} </ion-toggle> <div class="item"> <!-- 使用 pre 标签展示效果更美观 --> <div ng-bind="settingsList | json"></div> </div> <div class="item item-divider"> Notifications </div> <ion-toggle ng-model="pushNotification.checked" ng-change="pushNotificationChange()"> Push Notifications </ion-toggle> <div class="item"> <!-- 使用 pre 标签展示效果更美观 --> <div ng-bind="pushNotification | json"></div> </div> <ion-toggle toggle-class="toggle-assertive" ng-model="emailNotification" ng-true-value="Subscribed" ng-false-value="Unubscribed"> Newsletter </ion-toggle> <div class="item"> <!-- 使用 pre 标签展示效果更美观 --> <div ng-bind="emailNotification | json"></div> </div> </div> </ion-content> ``` 由于pre标签冲突，实例中的 pre 已替换为 div标签，具体可以在"尝试一下"中查看。 ### JavaScript 代码 ``` angular.module('ionicApp', ['ionic']) .controller('MainCtrl', function($scope) { $scope.settingsList = [ { text: "Wireless", checked: true }, { text: "GPS", checked: false }, { text: "Bluetooth", checked: false } ]; $scope.pushNotificationChange = function() { console.log('Push Notification Change', $scope.pushNotification.checked); }; $scope.pushNotification = { checked: true }; $scope.emailNotification = 'Subscribed'; }); ``` css 代码： ``` body { cursor: url('http://www.runoob.com/try/demo_source/finger.png'), auto; } ``` 效果如下所示：
