提供的大多数解决方案都适用于Angular 11以上的版本，对于Angular 11或以下版本，我找到了一个可以使用的变通方案:

export class UiButtonComponent implements OnInit, OnDestroy {

  @Input() disabled = false;

  clickEmitter: Subject<any> = new Subject();

  constructor(private elementRef: ElementRef) { }

  ngOnInit(): void {
    this.elementRef.nativeElement.eventListeners()
      .map(listener => this.clickEmitter.pipe(filter(event => Boolean(event))).subscribe(event => listener(event)));
    this.elementRef.nativeElement.removeAllListeners();
    this.elementRef.nativeElement.addEventListener('click', (event) => {
      if (!this.disabled) {
        this.clickEmitter.next(event);
      }
    });
  }

  ngOnDestroy(): void {
    this.clickEmitter.complete();
  }
}

我基本上把当前组件的每个侦听器都放在Observable上，然后，我只注册一个侦听器，并在那里管理操作。

上面的例子是在给定一个布尔变量的情况下禁用按钮上的click事件。

这招对我很管用:

mycomponent.component.ts:

action(event): void {
  event.stopPropagation();
}

mycomponent.component.html:

<button mat-icon-button (click)="action($event);false">Click me !<button/>

这解决了我的问题，从防止一个事件被一个孩子触发:

doSmth () { // what ever ｝ < div(点击)= " doSmth ()" > < div(点击)= " $ event.stopPropagation ()" > <组件> < /组件> < / div > < / div >

我不得不stopPropagation和preventDefault，以防止按钮展开上面的手风琴项。

所以…

@Component({
  template: `
    <button (click)="doSomething($event); false">Test</button>
  `
})
export class MyComponent {
  doSomething(e) {
    e.stopPropagation();
    // do other stuff...
  }
}

我刚刚检查了一个Angular 6应用程序，event. stoppropagation()在一个事件处理程序上工作，甚至不需要传递$event

(click)="doSomething()"  // does not require to pass $event


doSomething(){
   // write any code here

   event.stopPropagation();
}

试试这个指令

@Directive({
    selector: '[stopPropagation]'
})
export class StopPropagationDirective implements OnInit, OnDestroy {
    @Input()
    private stopPropagation: string | string[];

    get element(): HTMLElement {
        return this.elementRef.nativeElement;
    }

    get events(): string[] {
        if (typeof this.stopPropagation === 'string') {
            return [this.stopPropagation];
        }
        return this.stopPropagation;
    }

    constructor(
        private elementRef: ElementRef
    ) { }

    onEvent = (event: Event) => {
        event.stopPropagation();
    }

    ngOnInit() {
        for (const event of this.events) {
            this.element.addEventListener(event, this.onEvent);
        }
    }

    ngOnDestroy() {
        for (const event of this.events) {
            this.element.removeEventListener(event, this.onEvent);
        }
    }
}

使用

<input 
    type="text" 
    stopPropagation="input" />

<input 
    type="text" 
    [stopPropagation]="['input', 'click']" />
