//第一件事还是导包

//定义一个输入框
<input type="text" ng-model="data" />
<div id="one">{{data|mc}}</div>
<script>
  var mo = angular.module("myApp",[]);
  mo.controller("myCtrl",function($scope){
  });
  //自定义过滤器
  mo.filter("mc",function(){
   return function(input){
    //这个一定要加不然会报错
    if(input==undefined){
     input="";
    }
    //遍历全局有“哈”字就替换成“fuck”
    return input.replace(/哈/g,"fuck");
   }
  });
</script>
</body>

//一个简单的小案例

//建立输入框输入数据来查询数组内有没有有就展示

<body ng-app="myApp" ng-controller="myCtrl">
  用户名:<input type="text" ng-model="name"/><br/>
  密码:<input type="text" ng-model="pwd" />
  <span>{{pwd.length>6?"密码过长":""}}</span><br />
  {{names|mohu:name}}

  <script type="text/javascript">
   var mo = angular.module("myApp",[]);
   mo.controller("myCtrl",function($scope){
    $scope.names = ["zz","lxy","wmy","atm","atm1","atm2"];
   });
   mo.filter("mohu",function(){
    return function(input,n){
     var newArr = [];
     for(var i=0;i<input.length;i++){
      var name = input[i];
      if(name.indexOf(n)!=-1){
       newArr.push(name);
      }
     }
     return newArr;
    }
   })

  </script>
</body>
