javascript - 我如何按最近创建的列表列出提要中的帖子？

Question

我的后端使用 Onymos。当我从 onymos 中提取数据时，它为我提供了一个“排列方式”属性，我可以在其中指定“createdTime”作为值，但是，由于某种原因，这不会转移到我的模板中。从我的谷歌搜索中，我认为不再有按指令排序的 Angular 。所以我不确定我还能如何在我的模板中订购它。我的服务将一个数组传递给一个回调函数，该函数在 TS 主页的构造函数中触发。我为此悬赏了，因为有人提供的第一个解决方案对我不起作用..一直导致错误。

HOME.HTML

<ion-card id="card" *ngFor="let event of listOfEvents" >      

    <ion-row id="row1">
        <ion-col>
           <span class="showDetails">Date:</span>
           {{getFormattedTime(event.eventTime, 'MM-dd-yyyy')}}
        </ion-col>
        <ion-col>
            <span class="showDetails">Time:</span>
            {{getFormattedTime(event.eventTime, 'HH:MM')}}
        </ion-col>
        <ion-col>
            <span class="showDetails">Venue:</span>
            {{event.venue}}
        </ion-col>                                                   
    </ion-row>

</ion-card>

只需在客户端对其进行排序

function successCallback (listOfEventsObject) {

    for (var x in listOfEventsObject) {
        that.listOfEvents.push(listOfEventsObject[x]);
    }
    // sort
    that.listOfEvents = that.listOfEvents.sort(function(a, b) {
        return a.createdTime - b.createdTime;
        // or vice versa
        // or any other way you wish to sort
    });

}
