stackblitz：https://stackblitz.com/edit/angular-xk9nw6?file=src%2Fapp%2Ftable%2Ftable.component.html
我有一个json文件，其任务具有子任务属性，这些子任务具有与其父任务相同的属性类型。单击父任务时，子子任务需要附加到其父项的底部。我正在尝试使用自定义树网格而不使用这些刚性库
您可以在我的stackblitz中看到子任务正在所有父任务下填充，而不仅仅是它们所属的父任务。如果我将它移到父* ngfor中，我的子任务将被附加到每个父任务的底部，而不仅仅是它所属的父任务。
用于确定为什么subasks.taskName不会显示的奖励点，而subasks.taskID则显示。（奖励由Julien Bertacco解决）。谢谢，蓓蕾。

我的逻辑：
import { Component, OnInit,ViewChild } from '@angular/core';
import { sampleData } from '../datasource';
@Component({
selector: 'app-table',
templateUrl: './table.component.html',
styleUrls: ['./table.component.css']
})
export class TableComponent implements OnInit {
constructor() { }
@ViewChild('treegrid')
public data: Object[];
public foo: boolean;
public subtaskArray: any;
public index: number;
dropdown(e){
console.log(e);
}
subtask(e){
console.log(e);
this.subtaskArray = e.subtasks
this.index = e.taskID;
this.foo == false ? this.foo = true : this.foo = false;
}
ngOnInit(): void {
this.data = sampleData;
}
}
对于父任务下的填充子任务，您需要以这种方式循环
<tbody *ngFor="let datum of data; index as i">
<tr>
<td class="" (click)="subtask(datum, i); $event.stopPropagation()" >> </td>
<td class="">{{datum.taskID}}</td>
<td class="">{{datum.taskName}}</td>
<td class="btn btn.primary" (click)="dropdown(datum)">...</td>
</tr>
<tr [hidden]="index != i" *ngFor="let subtask of datum.subtasks" >
<td class="">> </td>
<td class="">{{subtask?.taskID}}</td>
<td class="">{{subtask?.taskName}}</td>
<td class=" btn btn.primary" (click)="dropdown(subtask)">...</td>
</tr>
</tbody>
并改变你的table.component.ts文件subtask函数
subtask(e,i){
this.subtaskArray = e.subtasks
this.index = i;
this.foo == false ? this.foo = true : this.foo = false;
}
<ul *ngFor="let datum of data">
<li>
<span (click)="subtask(datum); $event.stopPropagation()">></span>
{{datum.taskID}} {{datum.taskName}}
<ul [hidden]="!foo">
<li *ngFor="let subtask of subtaskArray">
{{subtask?.taskID}} {{subtask?.taskName}}
</li>
</ul>
</li>
</ul>
额外奖励：您编写了子任务而不是子任务
