我想知道当我将鼠标悬停在引导图标上时如何显示它的填充版本。

我有这个代码：

<svg
  width="80px"
  height="80px"
  viewBox="0 0 16 16"
  class="bi bi-cloud-plus"
  fill="#5cb85c"
  xmlns="http://www.w3.org/2000/svg"
>
  <path
    fill-rule="evenodd"
    d="M4.406 3.342A5.53 5.53 0 0 1 8 2c2.69 0 4.923 2 5.166 4.579C14.758 6.804 16 8.137 16 9.773 16 11.569 14.502 13 12.687 13H3.781C1.708 13 0 11.366 0 9.318c0-1.763 1.266-3.223 2.942-3.593.143-.863.698-1.723 1.464-2.383zm.653.757c-.757.653-1.153 1.44-1.153 2.056v.448l-.445.049C2.064 6.805 1 7.952 1 9.318 1 10.785 2.23 12 3.781 12h8.906C13.98 12 15 10.988 15 9.773c0-1.216-1.02-2.228-2.313-2.228h-.5v-.5C12.188 4.825 10.328 3 8 3a4.53 4.53 0 0 0-2.941 1.1z"

您可以使用mouseenter和mouseleave事件，并innerHTML根据是否悬停在图标上来更改图标的 。

 
document.getElementById('cloud-plus').addEventListener('mouseenter', function() {
  this.innerHTML = `<path fill-rule="evenodd" d="M8 2a5.53 5.53 0 0 0-3.594 1.342c-.766.66-1.321 1.52-1.464 2.383C1.266 6.095 0 7.555 0 9.318 0 11.366 1.708 13 3.781 13h8.906C14.502 13 16 11.57 16 9.773c0-1.636-1.242-2.969-2.834-3.194C12.923 3.999 10.69 2 8 2zm.5 4a.5.5 0 0 0-1 0v1.5H6a.5.5 0 0 0 0 1h1.5V10a.5.5 0 0 0 1 0V8.5H10a.5.5 0 0 0 0-1H8.5V6z"/>`
})

document.getElementById('cloud-plus').addEventListener('mouseleave', function() {
  this.innerHTML = `<path fill-rule="evenodd" d="M4.406 3.342A5.53 5.53 0 0 1 8 2c2.69 0 4.923 2 5.166 4.579C14.758 6.804 16 8.137 16 9.773 16 11.569 14.502 13 12.687 13H3.781C1.708 13 0 11.366 0 9.318c0-1.763 1.266-3.223 2.942-3.593.143-.863.698-1.723 1.464-2.383zm.653.757c-.757.653-1.153 1.44-1.153 2.056v.448l-.445.049C2.064 6.805 1 7.952 1 9.318 1 10.785 2.23 12 3.781 12h8.906C13.98 12 15 10.988 15 9.773c0-1.216-1.02-2.228-2.313-2.228h-.5v-.5C12.188 4.825 10.328 3 8 3a4.53 4.53 0 0 0-2.941 1.1z" />

通常实现这一点的方法是：

  1. 在您的标记中包含这两个元素（在这种情况下，包括填充和非填充版本），并具有共同的父级。
  2. 使用 CSS 隐藏填充版本
  3. 在:hover父级上，交换 CSS 以隐藏非填充版本并显示填充版本。

见下文：

.icon-wrapper .bi-cloud-plus-fill {
  display: none;
}

.icon-wrapper:hover .bi-cloud-plus-fill {
  display: inline;
}

.icon-wrapper:hover .bi-cloud-plus {
  display: none;
}

在它们之间进行转换是可能的，但有点困难，因为它需要一些定位技巧。我们必须让父母position: relative;让孩子们可以position: absolute坐在彼此之上。然后，display我们不是利用杠杆opacity来显示/隐藏，而是transition为opacity属性添加一个：

.icon-wrapper {
  position: relative
  display: inline-block;
  height: 1em;
  width: 1em;
  font-size: 36px;
}

.icon-wrapper .bi {
  position: absolute;
  top: 0;
  left: 0;
  transition: opacity 1s;
}

.icon-wrapper .bi-cloud-plus-fill {
  opacity: 0;
}

.icon-wrapper .bi-cloud-plus {
  opacity: 1;
}

.icon-wrapper:hover .bi-cloud-plus-fill {
  opacity: 1
}

.icon-wrapper:hover .bi-cloud-plus {
  opacity: 0;
}
<div class="icon-wrapper">

最后一件事——这些 SVG 本身并不是特别容易访问的。考虑利用Bootstrap 屏幕阅读器实用程序为可能没有查看您的网站的用户添加一些可访问的文本以进行导航。
