你應該使用自參照組件做到這一點:
@Component({
selector: 'app-tree-view',
templateUrl: './tree-view.component.html',
styleUrls: ['./tree-view.component.css']
})
export class TreeViewComponent implements OnInit {
@Input() data: {children: Array<any>,name: string,id: number};
showChildren: boolean;
}
在樹view.component.html:
<ul class="office-list-unstyled" *ngIf="data">
<li [ngClass]="{'office-parent': d.children.length && !showChildren,'office-child': d.children.length && showChildren}"
*ngFor="let d of data.children">
<span (click)="toggleOffices(d)">{{d.name}}</span>
<app-tree-view *ngIf="d.children.length && showChildren" [data]="d"></app-tree-view>
</li>
</ul>
需要注意的是,* ngIf的觀點是停止循環的事情。 然後你就可以在另一個組件使用它:
<app-tree-view [data]="offices"></app-tree-view>
辦事處是您例如初始數據。
