接入子组件参数从父

Question

我有以下代码

<div class="data-container" #dataContainer> 
<result (click)="onContainerClick($event, i)" *ngFor="let result of resultItems; let i = index" [result]="result" [index]="i"></result> 

每个结果具有参数 关闭：布尔;

我如何从TS代码中的父级访问？

感谢，

export class ParentComponent implements AfterViewInit { 
    @ViewChildren(ResultComponent) resultComps: QueryList<ResultComponent>;
