如何在Angular 2 ngFor Loop中使用本地引用获取元素的值?

请参阅下面的代码:

component.html

<tbody>
      <tr *ngFor="let storages of storageId; let i = index" (click)="storageSelected(i, storageWasSelected)">
        <td #storagewasselected>{{ storages.id }}</td>
        <td>{{ storages.storagetype }}</td>
        <td>{{ storages.islock }}</td>
        <td>{{ storages.createdby }}</td>
        <td>{{ storages.createddate }}</td>
      </tr>
    </tbody>

component.ts

@ViewChild('storagewasselected') storageWasSelected;

storageSelected(index: number, storageWasSelected){
  this.storageEntryService.StartEditStorage.next(index);
  this.selectedStorageId = storageWasSelected.innerHTML;
  console.log(this.selectedStorageId);
}

您可以直接在storageIndex()方法上传递索引,而不是使用ViewChild

(click)="storageSelected(storages.id)"

另外,你不需要这个

#storagewasselected

在你的模板上。
