如何使用angularjs从对象数组中获取id？

<div ng-app="myApp" ng-controller="myCtrl">
  <ul>
    <li ng-repeat="item in items">{{ item.id }}</li>
  </ul>
</div>

<script>
  var app = angular.module('myApp', []);
  app.controller('myCtrl', function($scope) {
    $scope.items = [
      { id: 1, name: 'item1' },
      { id: 2, name: 'item2' },
      { id: 3, name: 'item3' }
    ];
  });
</script>
