如何在不使用angular7中的事件发射器的情况下将数据从子组件传递到父数据？

Question

I need to get the data from child components oninit only. How to get that? Is it Possible or not?

When visiting the child component, parent components needs to print the name of that child component. How to do that ?

Answer 1

One way you can do this is using @ViewChild :

Add @ViewChild in your parent component:

export class ParentComponent {
  ...
  @ViewChild(ChildComponent) child: ChildComponent;
  ...

Now on parent's ngOnInit you will have access to your child component:

ngOnInit() {
  // this.child - will give you access to your child component
}
