Question

我对如何在对象数组中显示 categories.name 感到困惑。我要显示在第一个td.

<tr *ngFor="let innerItem of project.project_services">
    HERE--> <td>{{ innerItem.categories.[name]}</td>
    <td>{{innerItem.service.sku}}</td>
    <td>{{innerItem.service.name}}</td>
</tr>

Answer 1

<tr *ngFor="let innerItem of project.project_services">
    <td *ngFor="let categoryItem of innerItem.categories">{{categoryItem.name}</td>
    <td>{{innerItem.service.sku}}</td>
    <td>{{innerItem.service.name}}</td>
</tr>
