具有多个路径的SVG剪切路径的悬停事件

csshtmlsvgclip-path
3
我有一个SVG演示图像，其中包含多个圆圈对动画GIF进行裁剪。
用户在悬停在每个单独的圆圈上时，是否可以观察到其悬停事件？例如左上角圆圈或中间右侧圆圈。
此外，在悬停时是否可以操纵这些圆圈上的颜色叠加？
编辑：理想情况下，我希望悬停应用于悬停的圆圈并可点击以将某人带到另一页。
编辑2：在悬停时，除了更改覆盖颜色外，我希望在圆圈中心有文本。

这取决于你想要在悬停时实现什么。 - Temani Afif
我希望鼠标悬停在圆圈上时能够应用一种颜色，并且可以点击以将某人带到另一个页面。 - mattwillms

我会使用不同的元素来重新创建此内容，这样您就可以单独操纵它们。
我制作了9个孔，但是您可以通过从所需元素中删除背景来轻松减少它们，就像您的示例一样。

最简单的解决方案是将GIF移入SVG中，这样您就可以可靠地将覆盖圆与剪辑路径孔对齐。 

svg {
  width: 100%;
}

.overlay path {
  fill: red;
  fill-opacity: 0;
}

.overlay path:hover {
  fill-opacity: 0.5;
}

这个效果非常好！有没有办法在悬停时也让文本出现在圆圈中？ - mattwillms

将路径和文本放入一个组(<g>)元素中，然后将悬停样式应用于该组。例如：.overlay g:hover { ... }。 - Paul LeBeau
你能解释一下“scale trick”吗？我不太确定为什么要使用它。 - Temani Afif

@Temani 在<clipPath>中的比例将<path>元素转换为objectBoundingBox坐标。但是，当我们复制这些路径以在图像上使用时，我们需要将它们缩放以匹配图像大小(500 x 500)。为了实现这一点，我只需将剪辑路径变换值乘以500。例如: 0.00991 * 500 = 4.955。我可以使用的另一种选择是将clipPath切换到“userSpaceOnUse”并同时使用相同的转换。然而，我认为改变clipPath会令人困惑。我应该在我的答案中解释清楚所有这些。感谢您提醒我。 - Paul LeBeau

要使其可点击，您需要将每个路径放在... 标签中。然后为每个路径添加一个id，在css中只需执行a svg:hover #wave1 {code to change the element on hover}即可。
