在第二次单击时从元素中删除活动和焦点

Question

我正在尝试制作一个包含相关信息的互动地图。当您点击一个点时，它会调整大小并显示一些联系人。这是因为元素获得:active和:focus伪类。

有没有办法在第二次单击时从元素中删除伪类？实际上，是否可以在再次单击时使元素关闭？

.distribution-map {
  position: relative;
  width: 100%;
  padding: 20px;
  box-sizing: border-box;
  margin: 0 auto;
}
.distribution-map .map-point {
  cursor: pointer;
  outline: none;
  top: 20px;
  position: absolute;
  width: 40px;
  height: 40px;
  border-radius: 20px;
}
.distribution-map .map-point:active,
.distribution-map .map-point:focus {
  margin: 0;
  padding: 0;
  filter: opacity: 1;
  width: 300px;
  height: 220px;
  color: #e5e5e5;
  z-index: 1;
  -webkit-transition: opacity 0.25s ease-in-out, width 0.25s ease-in-out, height 0.25s ease-in-out;
  transition: opacity 0.25s ease-in-out, width 0.25s ease-in-out, height 0.25s ease-in-out;
}

<div class="distribution-map">
  <button class="map-point">
  </button>
</div>

Answer 1

这可以通过pointer-events: none;

来实现

通过将pointer-events: none;添加到焦点元素，您可以停止在元素上进行鼠标交互，从而有效地在下一次点击时不会聚焦。

需要进行以下修改：

• 将pointer-events: none;添加到.distribution-map .map-point:active, .distribution-map .map-point:focus

.distribution-map {
  position: relative;
  width: 100%;
  padding: 20px;
  box-sizing: border-box;
  margin: 0 auto;
}
.distribution-map .map-point {
  cursor: pointer;
  outline: none;
  top: 20px;
  position: absolute;
  width: 40px;
  height: 40px;
  border-radius: 20px;
}
.distribution-map .map-point:active,
.distribution-map .map-point:focus {
  margin: 0;
  padding: 0;
  filter: opacity: 1;
  width: 300px;
  height: 220px;
  color: #e5e5e5;
  z-index: 1;
  -webkit-transition: opacity 0.25s ease-in-out, width 0.25s ease-in-out, height 0.25s ease-in-out;
  transition: opacity 0.25s ease-in-out, width 0.25s ease-in-out, height 0.25s ease-in-out;
  pointer-events: none;
}

<div class="distribution-map">
  <button class="map-point">
  </button>
</div>
