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 >

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']" />

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!

在事件上调用stopPropagation来阻止传播:

(event)="doSomething($event); $event.stopPropagation()"

对于preventDefault只返回false

(event)="doSomething($event); false"

事件绑定允许执行按顺序执行的多条语句和表达式(由;比如*。ts文件。 如果是false，最后一个表达式的结果将导致preventDefault被调用。所以要小心表达式返回的内容(即使只有一个)

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();
}

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;
  }
}
