我正在使用 svg，我想使用 animate 标签对其进行动画处理，如下面的代码所示：

我的 Js 重复 ：
function func_call(){
setTimeout(function(){document.getElementById("svg_anim").setCurrentTime(0);
}
},2000);
}
此代码在Chrome，Firefox中工作正常，但在IE9中则不然。
我的问题：
有没有更好的方法从头开始重新启动动画。否则我的代码可以在IE9中工作。
需要帮助。这已经消耗了我几天的时间。
IE 的解决方法 - 使用假微笑
IE9 缺少动画支持，但支持通过脚本进行编程动画。
因此，在这种情况下，Fake Smile可以提供帮助。
您使用的是 SMIL(声明性(动画，这在 Internet Explorer 中不受支持。据我所知，Microsoft没有计划支持它。从此页面，
"基于脚本的动画为简单和复杂打开了大门 动画的可能性。因此，由于其他原因(例如 作为CSS动画(，IE9不支持声明性动画。
Microsoft真的希望您使用基于脚本的动画。因此，如果您希望SVG在所有当前浏览器中进行动画处理，则需要使用Javascript。或者，正如Microsoft所暗示的那样，您可以使用CSS动画。在我看来，CSS 动画将是示例中简单动画的最佳选择。
您可以使用 FakeSmile 库为 IE 添加动画支持
