Svg 路径宽度从 0 到 100% - CSS

Question

我有一个 SVG 电线。我想将线宽从“0 到 100%”设置为动画，但它没有发生。如果是 div，我可以很容易地做到这一点，但它是 SVG 图像。

这是我的代码：

svg path {
  animation: fadeRight 1s ease-in-out forwards;
}
@keyframes fadeRight {
  from {
    width: 0
  }
  to {
    width: 100%
  }
}

注意：我知道路径不能有宽度属性，我尝试了很多 事情，但没有找到任何解决方案。这就是为什么我提出问题 这里。建议我任何其他动画或我可以为其制作动画的东西。

动画：我需要一个 0% 到 100% 的动画，但缩放和平移无法做到这一点，比如您是否看到加载进度条从 0% 到 100% 顺利进行？就这样，不同的是，这条线是弯曲的，而装载机是直的。 请帮帮我，我卡住了。

Answer 1

• 您可以剪辑它并更改剪辑。我在下面展示了这个。

• 或者，您可以使用 stroke-dasharray 使其看起来像正在绘制线条。已经有很多这样的例子，例如this one

Answer 2

SVG 路径没有宽度属性，并且不能使用 CSS 宽度属性设置样式。而是使用scale transform。

svg path {
  animation: fadeRight 1s ease-in-out forwards;
}
@keyframes fadeRight {
  from {
    transform: scaleX(0)
  }
  to {
    transform: scaleX(1)
  }
}

Answer 3

你可以像这样改变宽度：

path{stroke-width:15}
