我不知道出了什么问题，但我遇到的每个错误都与 Safari 相关，而且非常烦人。我在我的网站上有一个代码，当用户鼠标不在页面主体上时，例如在另一个选项卡中或物理上不在页面上，圆形动画暂停，当用户鼠标再次返回主体时，css 动画恢复它停止的地方。它在 Chrome、Firefox 上完美运行......但在 Safari 上......它有蓝色背景，当你离开 body 时会弹出，当你返回时它会变得疯狂并立即开始所有颜色。有时它甚至不会在完成后启动，您必须刷新。这是我录制的 GIF。
当蓝色背景出现时:

当所有颜色同时开始时:

您好@thatoneguy90，这是因为 Safari 会在 1000 毫秒(1 秒)后暂停非事件选项卡上的 JS 以保留 CPU。您需要解决 setInterval 和 requestAnimationFrame 的自动暂停问题。当您在视口(viewport)外滚动时，这也可能导致蓝色。
一定要访问这个以获取有关如何使其工作的 JS 示例:
How can I make setInterval also work when a tab is inactive in Chrome?
您可能还会发现这有助于了解有关该主题的更多信息:
How do browsers pause/change Javascript when tab or window is not active?
此外，如果这接近最终结果，您也可以使用 CSS 来实现。
关于javascript - 动画播放状态在 Safari 上不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/43691545/
