在 Angular 11 中动态生成/生成现有组件

Question

I'm doing an web application that is supposed to work like the contacts app that we have in our phones:

1. Register contact info (name, email, number)
2. Click on save Button
3. List is updated immediately (here is my problem)

So I have a list.component (a grey mat-card) and a contact.component , (an orange mat-card).

I want to spawn a new contact.component inside of the list.component , and destroy it when the user select the delete button.

The data is passing fine, but I don't know how to add a new existing component inside another.

Answer 1

You could save the contacts inside a public array and then iterate over it inside the list-component:

  <list-component>
<ng-container *ngFor="let contact of contactArray"> 
<contact-component></contact-component>
 </ng-container>
</list-component>

When the user adds another contact, you can push it to the contactArray and the additional contact-component will appear
