Angular 2:单击链接时停止传播父元素的事件 [英] Angular 2 : Stop propagation of parent element's event , when clicking on link

问题描述

我有一个事件冒泡的情况.示例:

I have a case of event bubbling. Example :

<td (click)="doSomething()">
  <text [innerHtml]="content"> 
        //  content of innerHtml is :  <a href="http://google.com"></a>
  </text>
</td>

标签是通过innerHtml从另一个组件渲染的.问题:当我点击链接时，元素的点击事件也会被触发.如何解决问题(停止doSomething()的传播)，知道事件处理程序(或任何angular 2代码)不能通过innerHtml传递?

The tag is rendered from another component through innerHtml. The problem: when i click on the link, the click event of element is fired also. How to solve the problem (stop the propagation of doSomething()), knowing that event handlers(or any angular 2 code ) can't be passed through innerHtml?

谢谢！

推荐答案

解决方法 可以简单地将 (click)="$event.stopPropagation()" 放在 text 组件，这样事件就不会从托管组件中冒出来.同样的事情可以通过编写指令来即兴发挥.

Workaround could be simply placing (click)="$event.stopPropagation()" over text component, so that event will not get bubbled up from hosting component. Same thing can be improvise by writing a Directive.

<td (click)="doSomething()">
  <text (click)="$event.stopPropagation()" [innerHtml]="content"> 
        //  content of innerHtml is :  <a href="http://google.com"></a>
  </text>
</td>
