<small>上拉菜单(ActionSheet)通过往上弹出的框，来让用户选择选项。
非常危险的选项会以高亮的红色来让人第一时间识别。你可以通过点击取消按钮或者点击空白的地方来让它消失。</small>

HTML 代码
<body ng-app="starter" ng-controller="actionsheetCtl" >
<ion-pane>
<ion-content >
<h2 ng-click="show()">Action Sheet</h2>
</ion-content>
</ion-pane>
</body>
JavaScript 代码
<small>在代码中触发上拉菜单，需要在你的 angular 控制器中使用 $ionicActionSheet 服务：</small>
angular.module('starter', ['ionic'])
.run(function($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','$ionicActionSheet','$timeout'
,function($scope,$ionicActionSheet,$timeout){
$scope.show = function() {
var hideSheet = $ionicActionSheet.show({
buttons: [
{ text: '<b>Share</b> This' },
{ text: 'Move' }
],
destructiveText: 'Delete',
titleText: 'Modify your album',
cancelText: 'Cancel',
cancel: function() {
// add cancel code..
},
buttonClicked: function(index) {
return true;
}
});
$timeout(function() {
hideSheet();
}, 2000);
};
}])

ionic 背景层
<small>我们经常需要在 UI 上，例如在弹出框、加载框、其他弹出层中显示或隐藏背景层。
在组件中可以使用$ionicBackdrop.retain()来显示背景层，使用$ionicBackdrop.release()隐藏背景层。
每次调用retain后，背景会一直显示，直到调用release消除背景层。</small>

$scope.doRefresh = function() {
$http.get('http://www.runoob.com/try/demo_source/item.json') //注意改为自己本站的地址，不然会有跨域问题
.success(function(newItems) {
$scope.items = newItems;
})
.finally(function() {
$scope.$broadcast('scroll.refreshComplete');
});
};
}])
item.json 文件数据：
