我有两个组件:ParentComponent和ChildComponent:

parent.component.ts

<form #form="ngForm" (ngSubmit)="onSubmit(form)" novalidate>
     <input type="text" name="firstControl" [(ngModel)]="firstControl" />
     <input type="text" name="secondControl" [(ngModel)]="secondControl" />
     <child-component>
</form>
{{form.value | json}}

child.component.ts

<input type="text" name="thirdControl" [(ngModel)]="thirdControl" />
<input type="text" name="fourthControl" [(ngModel)]="fourthControl" />

现在,{{form.value | json}}回归{ "firstControl": "", "secondControl": "" }并且很清楚.我的问题是:有没有办法从子组件形成enherit表单控件？获取{ "firstControl": "", "secondControl": "", "thirdControl": "", "fourthControl": "" }ParentComponent 的正确方法是什么？可能吗？
