我想使用JavaScript暂停/恢复Android WebView上的SVG动画。
试过jsfiddle，但也没用http://jsfiddle.net/ysbo5zdw/1/

javascript在SVG元素中，但它不起作用。
根据John Ktejik的回答，svg动画可以在不丢失累积信息的情况下暂停吗？但没有运气
我的问题是我不想更改SVG文件，因为我需要修改很多SVG，这将是一项艰巨的任务。我想使用类似SVGroot.pauseAnimations((的文档https://developer.mozilla.org/en-US/docs/Web/API/SVGSVGElement或围绕的任何工作
这个答案在这里暂停一个外部SVG动画听起来不错，但我不知道如何在Android中实现它！
我建议你放
不同css类中的动画启动/停止功能：
svg.animation-on * {
animation-iteration-count: infinite;
}
svg.animation-off * {
animation-iteration-count: 0;
}
从现有样式表中删除任何其他animation-iteration-count设置
使用javascript将相应的类animation-on或animation off设置为顶级<svg>节点
