javascript - 如何在按钮单击时有条件地以 Angular 加载组件

Question

我对 Angular 还很陌生。

我想通过单击按钮有条件地在组件内加载子组件。单击按钮时，它应该重新渲染相应的子组件。

HTML 代码

<div class="tab">
  <button class="tablinks" (click)="onTabClick('0')">Transmit</button>
  <button class="tablinks" (click)="onTabClick('1')">Published</button>
  <button class="tablinks" (click)="onTabClick('2')">Bulk Transmit</button>
</div>
<div>
  <app-sports  *ngIf="tabIndex === 0"></app-sports>
  <app-movies  *ngIf="tabIndex === 2"></app-movies>
</div>

TS文件

tabIndex = 2 ;


  onTabClick(index){
        this.tabIndex = index;
   }

Answer 1

您已传递字符串作为参数，但检查选项卡中的数字。您可以查看 stackblitz 链接:

<div class="tab">
  <button class="tablinks" (click)="onTabClick(0)">Transmit</button>
  <button class="tablinks" (click)="onTabClick(1)">Published</button>
  <button class="tablinks" (click)="onTabClick(2)">Bulk Transmit</button>
</div>
<div>
  <app-sports  *ngIf="tabIndex === 0"></app-sports>
  <app-movies  *ngIf="tabIndex === 2"></app-movies>
</div>
