我從後端(api)獲取json數據。我想用ngFor顯示這個。我收到了如下錯誤消息:「無法從控制檯找到不同的支持對象'[object Object]'」。如何以角度顯示嵌套的對象和或數組2
後來我嘗試這樣做:
@Pipe({
name: 'mapToIterable'
})
export class MapToIterable implements PipeTransform{
transform(map: {}, args: any[] = null): any {
if (!map)
return null;
return Object.keys(map)
.map((key) => ({ 'key': key, 'value': map[key] }));
}
}
,然後在我的觀點:
<li *ngFor="let detail of getEventDetails | mapToIterable">
Creator Email: {{detail.creator.email}}
</li>
這個時候,我沒有得到一個錯誤,但有一種{{detail.creator.email}}
沒有顯示值來自後臺的數據

在此先感謝
這將不是這樣的工作。閱讀管道的代碼 - 你現在有一個數組中的鍵/值對象。檢查此plunker:http://plnkr.co/edit/wuVNDpVErNNiXlAn8GJk?p=preview – rinukkusu
感謝@rinukkusu它適用於我,但有沒有一種方法來值子陣 – adongo
不與'* ngFor'。沒有它,你可以使用'{{getEventDetails.creator.email}}'。 – rinukkusu
