8.1. 排序 orderBy

`orderBy` 是一个排序用的过滤器标签。它可以像 `sort` 函数那样支持一个排序函数，也可以简单地指定一个属性名进行操作：

  <div ng-controller="TestCtrl">
    { { data | orderBy: 'age' } } <br />
    { { data | orderBy: '-age' } } <br />
    { { data | orderBy: '-age' | limitTo: 2 } } <br />
    { { data | orderBy: ['-age', 'name'] } } <br />
  </div>


  <script type="text/javascript">
  var TestCtrl = function($scope){
    $scope.data = [
      {name: 'B', age: 4},  
      {name: 'A', age: 1},  
      {name: 'D', age: 3},  
      {name: 'C', age: 3},  
    ];
  }

  angular.bootstrap(document.documentElement);
  </script>
