在函数后添加false将停止事件传播

<a (click)="foo(); false">click with stop propagation</a>

如果您希望能够将此添加到任何元素，而不必一遍又一遍地复制/粘贴相同的代码，您可以制作一个指令来完成此操作。如下图所示:

import {Directive, HostListener} from "@angular/core";
    
@Directive({
    selector: "[click-stop-propagation]"
})
export class ClickStopPropagation
{
    @HostListener("click", ["$event"])
    public onClick(event: any): void
    {
        event.stopPropagation();
    }
}

然后将它添加到你想要它的元素:

<div click-stop-propagation>Stop Propagation</div>

我使用

<... (click)="..;..; ..someOtherFunctions(mybesomevalue); $event.stopPropagation();" ...>...

简而言之，只需用';'分隔其他事物/函数调用，并添加$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']" />

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。

用JavaScript禁用href链接

<a href="#" onclick="return yes_js_login();">link</a>

yes_js_login = function() {
     // Your code here
     return false;
}

它应该如何在TypeScript和Angular中工作(我的版本:4.1.2)

Template

<a class="list-group-item list-group-item-action" (click)="employeesService.selectEmployeeFromList($event); false" [routerLinkActive]="['active']" [routerLink]="['/employees', 1]">
    RouterLink
</a>

TypeScript

public selectEmployeeFromList(e) {

    e.stopPropagation();
    e.preventDefault();

    console.log("This onClick method should prevent routerLink from executing.");

    return false;
}

但是它没有禁用routerLink的执行!
