如何在ngb-tabset

中动态创建标签

组件代码

 tabs = ['Tab-1','Tab-2'];

HTML代码

<ngb-tabset #tabs>
  <ngb-tab *ngFor="let tab of tabs" [title]="tab">
    <ng-template ngbTabContent>
       Some Data
    </ng-template>
  </ngb-tab>
</ngb-tabset>

我收到错误

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

这里发生的是您为要创建名为tabs的本地var的元素使用相同的名称。这就是* ngFor尝试迭代的内容，而不是名为tabs的组件变量。

我建议您将任何名称更改为其他名称，然后重试。

如何在ngb-tabset中使用* ngFor？
