ionic 复选框+单选框+切换开关操作

ionic 复选框

ionic 复选框（checkbox）与普通的 HTML 复选框没什么区别，以下实例演示了 ionic 复选框 ion-checkbox 的应用。

<ion-checkbox ng-model="isChecked">复选框标签</ion-checkbox>

实例
实例中，会根据复选框是否选中，修改 checked 值，true 为选中， false 为未选中。
[HTML 代码]

<ion-header-bar class="bar-positive"> 
  <h1 class="title">复选框</h1>
</ion-header-bar> 

<ion-content> 
  <div class="list"> 

    <ion-checkbox ng-repeat="item in devList" ng-model="item.checked" ng-checked="item.checked"> 
      {{ item.text }} 
    </ion-checkbox> 

    <div class="item"> 
      <div ng-bind="devList | json"></div> 
    </div> 

    <div class="item item-divider"> 
      Notifications 
    </div> 

    <ion-checkbox ng-model="pushNotification.checked" ng-change="pushNotificationChange()"> 
      Push Notifications 
    </ion-checkbox> 

    <div class="item"> 
      <div ng-bind="pushNotification | json"></div> 
    </div> 

    <ion-checkbox ng-model="emailNotification" ng-true-value="'Subscribed'" ng-false-value="'Unubscribed'"> 
      Newsletter 
    </ion-checkbox> 

    <div class="item"> 
      <div ng-bind="emailNotification | json"></div> 
    </div> 

  </div> 
</ion-content>

[JavaScript 代码]

angular.module('starter', ['ionic'])
  .run(function($ionicPlatform) {
    $ionicPlatform.ready(function() { 
      // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard 
      // for form inputs) 
      if(window.cordova && window.cordova.plugins.Keyboard) { 
        cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true); 
      } 
      if(window.StatusBar) { 
        StatusBar.styleDefault(); 
      }
    });
  })

  .controller( 'actionsheetCtl',['$scope',function($scope){ 
    $scope.devList = [ 
      { text: "HTML5", checked: true }, 
      { text: "CSS3", checked: false }, 
      { text: "JavaScript", checked: false }
    ]; 
    $scope.pushNotificationChange = function() { 
      console.log('Push Notification Change',$scope.pushNotification.checked); 
    }; 
    $scope.pushNotification = { checked: true }; 
    $scope.emailNotification = 'Subscribed';
  }])

ionic 单选框操作

实例中，根据选中的不同选项，显示不同的值。
[HTML 代码]

<ion-header-bar class="bar-positive"> 
  <h1 class="title">当选按钮</h1>
</ion-header-bar> 

<ion-content> 
  <div class="list"> 

    <div class="item item-divider"> 
      选取的值为: {{ data.clientSide }} 
    </div> 

    <ion-radio ng-repeat="item in clientSideList" ng-value="item.value" ng-model="data.clientSide"> 
      {{ item.text }} 
    </ion-radio> 

    <div class="item item-divider"> 
      Serverside, Selected Value: {{ data.serverSide }} 
    </div> 

    <ion-radio ng-repeat="item in serverSideList" ng-value="item.value" ng-model="data.serverSide" ng-change="serverSideChange(item)" name="server-side"> 
      {{ item.text }} 
    </ion-radio> 

  </div> 
</ion-content>

[JavaScript 代码]

angular.module('ionicApp', ['ionic'])
  .controller('MainCtrl', function($scope) { 
    $scope.clientSideList = [ 
      { text: "Backbone", value: "bb" }, 
      { text: "Angular", value: "ng" }, 
      { text: "Ember", value: "em" }, 
      { text: "Knockout", value: "ko" } 
    ]; 
    $scope.serverSideList = [ 
      { text: "Go", value: "go" }, 
      { text: "Python", value: "py" }, 
      { text: "Ruby", value: "rb" }, 
      { text: "Java", value: "jv" } 
    ]; 
    $scope.data = { clientSide: 'ng' }; 
    $scope.serverSideChange = function(item) { 
      console.log("Selected Serverside, text:", item.text, "value:", item.value);
    }; 
  });

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;
