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...
  }
}

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!

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']" />

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...
  }
}
