  </style> 
  <script src="angular.min.js"></script> 
  <script> 
    /* 
     1、基本布局 
     2、准备模拟数据 
     */ 
    // 模拟数据 
    var data = { 
      user:"吴四", 
      items:[ 
        {action:"约刘诗诗吃饭",done:false}, 
        {action:"约刘诗诗跳舞",done:false}, 
        {action:"约刘诗诗敲代码",done:true},

        {action:"约刘诗诗看电影",done:false} 
      ] 
    }; 
    var myapp=angular.module("myapp",[]); 
    /*这里的是自定义过滤器，将数组items 过滤之后返回arr*/ 
    myapp.filter("doFilter",function(){ 
      /*传入两个参数，一个数组items，另一个是complate*/ 
      return function(items,flag){ 
        var arr=[]; 
        /*遍历items,如果dones是false或者下边的按钮在选中状态，就将这一条item push到arr中*/ 
        for(var i=0;i<items.length;i++){ 
          if(items[i].done==false){ 
            arr.push(items[i]); 
          }else{ 
            if(flag==true){ 
              arr.push(items[i]); 
            } 
          } 
        } 
        return arr; 
      } 
    }); 
    myapp.controller("myCtrl",function($scope){ 
      $scope.data=data; 
      $scope.complate=false; 
      /*判断还有几件事儿没有完成*/ 
      $scope.count=function(){ 
        var n=0; 
        /*判断还有几件事儿没有完成*/ 
        for(var i=0;i<$scope.data.items.length;i++){ 
          if($scope.data.items[i].done==false){ 
            n++; 
          } 
        } 
        return n; 
      }; 
      /*添加新的日程*/ 
      $scope.add=function(){ 
        /*对$scope.action进行一下非空判断*/ 
        if($scope.action){ 
          /*如果输入了内容之后，就在数组的最后加入一条新内容*/ 
          $scope.data.items.push({"action":$scope.action,"done":false}); 
          /*添加完成之后，将input置空*/ 
          $scope.action=""; 
        } 
      }; 
    }); 
  </script> 
</head> 
<body ng-app="myapp" ng-controller="myCtrl">
