CSS伪元素上的事件监听器,例如:: after和:: before?

CSS伪元素上的事件监听器,例如:: after和:: before?

问题描述:

我有一个 div 元素,其中CSS伪元素 :: before 用作关闭按钮(而不是使用实际按钮)。如何将事件监听器仅应用于 伪元素?

I have a div element with a CSS pseudo-element ::before used as a close button (instead of using an actual button). How do I apply an event listener to only the pseudo-element?

HTML

<div id="box"></div>

CSS

#box:before
{
 background-image: url(close.png);
 content: '';
 display: block; 
 height: 20px;
 position: absolute;
 top: -10px;
 right: -10px; 
 width: 20px;
}

#box
{
 height: 100px;
 width: 100px;
}


不。 DOM中不存在伪元素,因此它没有表示它的 HTMLElementNode 对象。

No. The pseudo-element does not exist in the DOM so it has no HTMLElementNode object representing it.
