如何停止 SVG CSS 动画



我有一个SVG动画，我正在尝试弄清楚如何在动画序列完成后立即停止并保留SVG的视图。这样，徽标将保留在页面上，直到下一页刷新等。

这是演示：https://jsfiddle.net/u410bjyk/

我知道我可以删除"无限"属性来运行它一次，但问题是，你如何在之后立即停止它？

您可以使用以下命令暂停 CSS 动画：

animation-play-state: paused;

我在您的示例中添加了一个按钮，可让您随时停止动画。

function stop() {
  $(".pin__group, .pin__grayGroup, .pin__square, .pin__line-1, .pin__line-2, .pin__line-3, .pin__circleBig, .pin__circleSmall, .pin__outer, .pin__inner").addClass("stop");
}
