如何在angular中将参数拆分为两个文本框作为标签?单击复选框后如何在html中显示？

<input type="text" [(ngModel)]="firstParam">
<input type="text" [(ngModel)]="secondParam">
<input type="checkbox" (change)="showParams($event.target.checked)">
<div *ngIf="show">
  <p>第一个参数：{{ firstParam }}</p>
  <p>第二个参数：{{ secondParam }}</p>
</div>

export class YourComponent {
  firstParam: string;
  secondParam: string;
  show: boolean;

  showParams(checked: boolean) {
    this.show = checked;
  }
}
