在formarray中存储并显示输入消息

Question

我创建了一个输入字段，用户可以在其中输入消息，然后在键入输入我要显示此消息的键输入中。

export class AppComponent  {
 
  myForm: FormGroup;

  constructor(private fb: FormBuilder) {
    this.createForm();
  }


  onEnter() {
    this.addThing();
  }

  get things() {
    return this.myForm.get('things') as FormArray;
  }

  private createForm() {
    this.myForm = this.fb.group({
      things: this.fb.array([
        this.fb.control('')
      ])
    });
  }

  private addThing() {
    this.things.push(this.fb.control(''));
  }
}

HTML：

<div class="display-text">
                            <p
                               *ngFor="let thing of things.controls; let i=index">{{thing.value}}
                            >
                                {{ message.value | json}}
                            </p>
                        </div>
<div class="input">
                <form [formGroup]="myForm">
                    <ng-container formArrayName="things">
                        <ng-container
                            ngFor="let thing of things.controls; let i = index "
                        >
                            <input
                                type="text"
                                (keyup.enter)="onEnter()"
                            />
                        </ng-container>
                    </ng-container>
                </form>
            </div>

按Enter，该消息未显示在窗口中。有人可以帮忙吗？
