CSS动画无法在IE / Edge中使用

Question

这件事在IE / Edge中如何运作？ 我不明白为什么没有。

当我将一个类添加到元素时，其边框变为虚线并开始旋转。

 $("#btn").click(function () { $(".bg")[0].classList.toggle("rotate"); }) 

 @keyframes PDFgenerating { to { -moz-transform: rotate(360deg); -ms-transform: rotate(360deg); -o-transform: rotate(360deg); -webkit-transform: rotate(360deg); transform: rotate(360deg); } } .bg circle { fill:white; stroke: blue; } .bg circle { -moz-transition : stroke-dasharray cubic-bezier(0.4, 0, 0.2, 1) .7s; -o-transition : stroke-dasharray cubic-bezier(0.4, 0, 0.2, 1) .7s; -webkit-transition: stroke-dasharray cubic-bezier(0.4, 0, 0.2, 1) .7s; transition : stroke-dasharray cubic-bezier(0.4, 0, 0.2, 1) .7s; stroke-dasharray : 290 !important; } .bg.rotate circle { -moz-transition: stroke-dasharray cubic-bezier(0.4, 0, 0.2, 1) .7s; -o-transition: stroke-dasharray cubic-bezier(0.4, 0, 0.2, 1) .7s; -webkit-transition: stroke-dasharray cubic-bezier(0.4, 0, 0.2, 1) .7s; transition: stroke-dasharray cubic-bezier(0.4, 0, 0.2, 1) .7s; -moz-animation: PDFgenerating linear 5s infinite reverse; -o-animation: PDFgenerating linear 5s infinite reverse; -webkit-animation: PDFgenerating linear 5s infinite reverse; animation: PDFgenerating linear 5s infinite reverse; stroke-dasharray: 28 !important; -moz-transform-origin: center; -ms-transform-origin: center; -o-transform-origin: center; -webkit-transform-origin: center; transform-origin: center; }

我已经尝试在trasform-origin中使用％，并在关键帧中使用0％和100％，这在一些非常相似的问题中可以找到。

Answer 1

如果通过IE中的CSS使用SVG上的转换似乎不起作用，并且为什么旋转动画不起作用
找到了此SO链接，该链接解释了SVG Elements IE9 +上的CSS转换
并且在IE站点中也记录为错误https://connect.microsoft.com/IE/feedback/details/811744/ie11-bug-with-implementation-of-css-transforms-in-svg

 $("#btn").click(function () { $(".bg")[0].classList.toggle("rotate"); })

这可能是没有CSS转换的替代方法，但在IE / Edge上仍然无法使用。
