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();
}

IE (Internet Explorer)什么都不行。我的测试人员可以通过点击后面弹出窗口的按钮来破坏我的模式。所以，我听了我的模式屏幕div的点击声，并强制重新聚焦在一个弹出按钮上。

<div class="modal-backscreen" (click)="modalOutsideClick($event)">
</div>


modalOutsideClick(event: any) {
   event.preventDefault()
   // handle IE click-through modal bug
   event.stopPropagation()
   setTimeout(() => {
      this.renderer.invokeElementMethod(this.myModal.nativeElement, 'focus')
   }, 100)
} 

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!

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/>

补充来自@AndroidUniversity的答案。在单行中你可以这样写:

<component (click)="$event.stopPropagation()"></component>

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']" />
