我正在通过 youtube 学习 angular，但我正在尝试做一些新的事情，但我遇到了一个错误，我的代码附在下面，帮帮我。

我想像这样设置属性，div.setAttribute('(click)',"popUp($event)");但出现错误。

打字稿

export class AppComponent {
    createEl(){
      console.time("timer");
      for (let i = 0; i < 10; i++) {
        let div = document.createElement("div");
        div.textContent = `Hello, World! ${i}`;
        div.setAttribute('(click)',"popUp($event)");
        document.getElementById('divEl')?.appendChild(div);
      };
      console.timeEnd("timer");
}

HTML

<div></div>
<button (click)="createEl()">click me</button>

错误

回答

<div>
  <div *ngFor="let row of rows; index as i;" (click)="popUp($event)">
    Hello, World! {{i}}
  </div>
</div>

<button (click)="createEl()">click me</button>

export class AppComponent {
  rows: unknown[] = [];
  createEl():void {
    this.rows.push('something');
  }

  popUp(event:Event):void {}
}
