我有一个JSON对象,其中包含不同的事件,如下所示:
- {
- "error":false,"events":[
- {
- "id":1,"title":"First entry","date":"2014-11-04"
- },{
- "id":2,"title":"Second entry",{
- "id":3,"title":"Third entry","date":"2014-11-05"
- },{
- "id":4,"title":"Fourth entry","date":"2014-11-06"
- },{
- "id":5,"title":"Fifth entry","date":"2014-11-06"
- }
- ]
- }
该对象存储在我的控制器的$scope.events中.
现在我循环这个数组来构建事件列表:
- <ion-list>
- <div class="item item-divider">
- {{event.date}}
- </div>
- <a class="item item-thumbnail-left" href="#/app/event/{{event.id}}" ng-repeat="event in events">
- <img src="media/thumbnails/{{event.id}}.jpg">
- <h1>{{event.title}}</h1>
- </a>
- </ion-list>
我的目标是每天只将{{event.date}}显示为列表分隔符一次.所以在这个考试中,它看起来像这样:
2014-11-04(分频器)
>第一次进入
>第二次入境
2014-11-05(分频器)
>第三次进入
2014-11-06(分频器)
>第四次进入
>第五次入境
我非常喜欢离子和放大器角度,我不知道如何实现这一目标.可能有一些自定义过滤器?
总而言之,我正在寻找类似于Angular: Getting list with ng-repeat with dividers / separators的东西,但日期为分隔符而不是首字母.
一些想法?
任何帮助/提示真的很感激!
您可以使用angular.filters(
https://github.com/a8m/angular-filter)按日期对列表进行分组,请参阅下面的演示
- var app = angular.module('app',['angular.filter']);
- app.controller('homeCtrl',function($scope) {
- $scope.data = {
- "error": false,"events": [{
- "id": 1,"title": "First entry","date": "2014-11-04"
- },{
- "id": 2,"title": "Second entry",{
- "id": 3,"title": "Third entry","date": "2014-11-05"
- },{
- "id": 4,"title": "Fourth entry","date": "2014-11-06"
- },{
- "id": 5,"title": "Fifth entry","date": "2014-11-06"
- }]
- }
- });
