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']" />

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>

最简单的方法是在事件处理程序上调用停止传播。$event在Angular 2中的工作原理是一样的，它包含了正在发生的事件(鼠标点击、鼠标事件等等):

(click)="onEvent($event)"

在事件处理程序中，我们可以停止传播:

onEvent(event) {
   event.stopPropagation();
}

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!

如果你在一个绑定到事件的方法中，简单地返回false:

@Component({
  (...)
  template: `
    <a href="/test.html" (click)="doSomething()">Test</a>
  `
})
export class MyComp {
  doSomething() {
    (...)
    return false;
  }
}
