我有一个 svg 组,其中包含一系列路径,这些路径代表饼图的不同区域,这些路径由圆形标记覆盖,图形显示为圆环图。

我希望整体效果是这样的:https://codepen.io/seanstopnik/pen/GqHng

有很多使用 stroke-dasharray 作为线条的例子,但我还没有找到任何可以为多条路径设置动画的东西!执行此操作的最佳方法是什么?

最佳答案

按照常规方法,您没有要设置动画的笔划。所以你可以做的是将动画描边线变成一个蒙版。然后将该面具应用于更复杂的形状。

#progress circle {
animation: do-progress 4s infinite;
}

@keyframes do-progress {
0% { stroke-dashoffset: 0px; }
50% { stroke-dashoffset: -146px; }
100% { stroke-dashoffset: 0px; }
}
