我遇到的问题只会影响IE和Edge（在IE9-11 & Edge 12-13上测试过）。我使用Snap.svg为SVG笔画偏移设置了动画效果，似乎可以正常运行，但在某些时候，笔画看上去会“超出界限”并消失。这很奇怪，因为viewBox被设置为与线条完全吻合（它直接从Illustrator中导出，并带有适合整条线的美工板）。SVG动画在IE和Edge上出现“越界”

在技术笔记上，不要浪费时间在IE9和IE10上 - 微软在今年1月12日停止使用它们，除了那些只能使用IE9的Vista SP2用户，并且可能仍然在MS的扩展支持范围内;但只有当他们是一个企业，而不是在家的普通人（我确信你不是针对这里的企业）。新的MS政策是“我们只支持IE的最新版本”，这就是IE11，一旦Edge登陆，IE11也将失去支持。 –
谢谢Mike，我完全同意。我并不十分关心IE10，但IE11和Edge的最新版本似乎都有这个问题，所以我认为这值得讨论，因为无论最新的蹩脚浏览器微软发布，哈哈。 – ndimatteo
请注意，如果它是一个bug，MS自从鲍尔默被踢出后已经发生了相当大的变化，所以你可以在https://developer.microsoft.com/en-us上的* public issue tracker */microsoft-edge/platform/issues /这几天（这太棒了） –
