在控制器中使用groupby的AngularJs过滤器

{{ expression | groupby: property }}

$scope.items = [
  { name: 'Apple', category: 'Fruit' },
  { name: 'Banana', category: 'Fruit' },
  { name: 'Carrot', category: 'Vegetable' },
  { name: 'Tomato', category: 'Vegetable' }
];

<div ng-repeat="(category, items) in items | groupby: 'category'">
  <h3>{{ category }}</h3>
  <ul>
    <li ng-repeat="item in items">{{ item.name }}</li>
  </ul>
</div>
