我已经把下面的json放到了一个名为logs的数组中,并且希望使用创建的时间戳对每周进行分组。如何在打字稿/离子2中按星期分组时间戳?

{ 
    created : "2017-07-15 09:49:37" 
    entry : "this is a log entry" 
} 
    created : "2017-07-13 09:49:37" 
    entry : "this is a log entry" 
} 
{ 
    created : "2016-05-13 11:00:21" 
    entry : "this is another log entry" 
} 

和离子2 html。

<div *ngFor="let log of logs"> 
     <ion-list-header> 
      {{log.created}} 
     </ion-list-header> 
    <ion-item> 
     {{log.entry}} 
    </ion-item> 
</div>

好,我现在在做PHP每周分组返回下面的JSON,

"payload": { 
"logs": { 
    "19": [ 
    "[{\"entry\":"this is an entry",\"created\":\"2017-05-12 09:51:18\"}]" 
    ], 
    "28": [ 
    "[{\"entry\":"this is an entry",\"created\":\"2017-07-15 09:50:50\"}]", 
    "[{\"entry\":"this is an entry",\"created\":\"2017-07-15 09:51:18\"}]" 
    ] 
} 

我收到像这样,

private weeks: any[]; 

this.api.getLogs().subscribe(
     data => { 
     // Success 
     this.weeks = data.payload.logs; 
     }, 
     err => { 
     //Err 
     } 
    ); 

,我试图在Ionic 2中使用它,

<div *ngFor="let week of weeks"> 
    <div *ngFor="let log of week"> 
     {{log.created}} 
    </div> 
</div> 

但给了我下面的错误,

Runtime Error 
Cannot find a differ supporting object '[object Object]' of type 'object'. NgFor only supports binding to Iterables such as Arrays. 

任何帮助表示赞赏。

嗨,我已编辑帖子以显示我目前的情况。我已经在PHP方面分了几周,但我有问题让json进入列表。 – Dunny

您声明weeks为任何(private weeks: any[];)数组,但你用JSON(data.payload.logs是JSON)设置它,这样看来,你至少有一个类型的错误在这里。
