Angular-MCQ-一次验证多个问题

Question

我正在Angular 6中处理MCQ。目前，每个问题都通过相同的方法进行验证（在每个按钮的一个按钮中，单击（click）=“ reponseValide（question）”）。我想用一个按钮来验证每个问题。 你能给我一些例子吗？

questionnaire.component.html

<h4>Repondez aux questions !</h4>

<div *ngFor="let question of questions">{{question.id}} - {{question.libelle}} 

    <button  type="button" routerLink="/resultat" class="btn btn-success">Changer</button> 

    <button  class="btn btn-danger">supprimer</button>

     <div class="row text-left options">
        <app-reponse [question]="question"></app-reponse>
     </div>
</div>

<!-- <button type="button" routerLink="/resultat" class="center btn btn-primary">Valider</button> -->

Reponse.component.html

<div class="" *ngFor="let reponse of reponses">
    <div class="reponse">
        <label class="container"> 

            <input type="checkbox" [(ngModel)]="reponse.bonne" /> {{reponse.libelle}}
        </label>
    </div>
</div>

 <button (click)="reponseValide(question)" >Valider question</button>

Reponse.component.ts

 reponseValide(question) {
    this.questionnaireService.reponseValide(question).subscribe(retour => {
      if (retour) {
        console.log('OK');
      } else {
        console.log('KO');
      }
    });
  }

questionnaire.service.ts

reponseValide(question: any) {
    return this.http.post<any>(`${environment.apiUrl}question/reponsesValide`, question);
  }

您将如何做？
