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"
}]
}
});
