  <!--记得导入ionic包和ionic样式-->
  <script src="js/ionic.bundle.min.js" type="text/javascript" charset="utf-8"></script>
  <link rel="stylesheet" type="text/css" href="css/ionic.css" rel="external nofollow" />
  <!--
   ionic
   angular
    $http--服务
    ng- 指令
    表达式 {{}}
   刷新案例
    ul--
    数据
  -->
 </head>
 <body ng-app="myApp" ng-controller="myCtrl">
  <ion-header-bar class="bar-calm">
   <h1 class="title">下拉刷新</h1>
  </ion-header-bar>
  <ion-content>
   <!--

    ion-refresher
     pulling-text 下拉的时候显示的文本
     pulling-icon 图标
     onRefresh 当刷新的时候调用的方法
   -->
   <ion-refresher pulling-text="松手刷新..." on-refresh = "doRefresh()" pulling-icon="img/arrow-down-c.png">
   </ion-refresher>
   <ul class="list">
    <li class="item" ng-repeat="good in goods">{{good.gname}}</li>
   </ul>
  </ion-content>
  <!--
   angular
    mvc 视图 view 各种标签，数据 ng-model{{}} ，控制器 controller 逻辑代码
    指令：一个特殊的属性
    表达式 ： 一段代码 ，主要功能：取数据，可以进行运算
    模块：一些功能和视图组成的整体
    服务：就是一个方法，满足一些需要而定义的方法。内置服务30多个
      $http
    内置过滤器：9个
      管道符 |

  <script type="text/javascript">
   //创建模块
   var mod = angular.module("myApp",["ionic"]);//[]里面的是需要注入的对象。两个:ngRoute /ionic
   //创建控制器
   mod.controller("myCtrl",function($scope,$http){
    //定义数组、也就是model数据
    $scope.goods=[{"gname":"秋裤"},{"gname":"羽绒服"}];
    //刷新的方法
    $scope.doRefresh=function(){
     //请求网络，加载数据
     $http.get("data.json").then(function(req){
      //取得数据 ,req将数据封装到data属性里面了
      var d = req.data;
      //将一个集合整个加入另外一个集合contact()
//      $scope.goods= $scope.goods.contact(d);
      for (var i =0;i<d.length;i++) {
       $scope.goods.unshift(d[i]);
      }
      //结束刷新
      $scope.$broadcast("scroll.refreshComplete");
     },function(req){
      alert("失败");
     });
//     .finally(function(){
//      
//     });
    }
   });
  </script>
