接入子組件參數從父

Question

我有以下代碼

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

每個結果具有參數 關閉：布爾;

我如何從TS代碼中的父級訪問？

感謝，

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