如何获得角形的无功形式值分量？

Question

How to access the value of each of the iterated forms of the child component ?. The parent component has a button which must generate an array of child forms, but must go through all those forms. Can it be with a viewChid?

HTML

<form novalidate
  [formGroup]="fatherForm">
    <div *ngFor="let item of items>
      <children-form
        [item]="item">
      </children-form>
    </div>
</form>

TS

<button (click)="save()">Save</button>

Maybe you can use @ViewChildren , here is a demo.

@ViewChildren(ChildrenFromComponent)
childrenFormCmps: QueryList<ChildrenFromComponent>;

ngAfterViewInit() {
    console.dir(this.childrenFormCmps);
}
