整理文档，搜刮出一个angularjs使用$watch和$filter过滤器制作搜索筛选，稍微整理精简一下做下分享。

<div ng-app="module" ng-controller="ctrl">
  搜索: <input type="text" ng-model="search">
  <table border="1" width="600">
    <tr>
      <td>编号</td>
      <td>点击数</td>
      <td>标题</td>
    </tr>
    <tr ng-repeat="(k,v) in lists">
      <td>{{v.id}}</td>
      <td>{{v.click}}</td>
      <td>{{v.title}}</td>
    </tr>
  </table>
</div>
<script>
  var m = angular.module('module', []);
  m.controller('ctrl', ['$scope', '$filter', function ($scope, $filter) {
    $scope.data = [
      {id: 1, click: 100, title: '百度'},
      {id: 2, click: 200, title: '腾讯'},
      {id: 3, click: 300, title: '谷歌'},
    ];
    //临时数据用于显示
    $scope.lists = $scope.data;
    $scope.$watch('search',function(n,o){
      $scope.lists = $filter('filter')($scope.data,n);
    });
  }]);
</script>
