javascript - 从已经包含动画的文件渲染和动画化 SVG

Question

我正在开发一个 reactjs 网络应用程序。我有一个已经包含动画的 svg 微调器文件。我想知道是否有一种方法可以在 rectjs 上渲染它(包括动画)。我已经在渲染 svg 图像，但是当我使用与此相同的 clase 时，没有渲染任何东西。我认为这是因为动画。

有办法从 svg 中“提取”动画并将其转换为关键帧吗？

这是 svg 文件:

非常感谢!

我不确定我是否理解“提取”的意思，但请注意 React 支持 SVG:

定义:

const Spinner = () => (
  <svg width='48px' height='48px' xmlns="http://www.w3.org/2000/svg" viewBox="0 0 100 100" preserveAspectRatio="xMidYMid" className="uil-default">
    <rect x="0" y="0" width="100" height="100" fill="none" className ="bk" />
    <rect  x='47' y='40' width='6' height='20' rx='3' ry='3' fill='#000000' transform='rotate(0 50 50) translate(0 -30)'>
      <animate attributeName='opacity' from='1' to='0' dur='1s' begin='-1s' repeatCount='indefinite'/>
    </rect>
  ...
  </svg>);

然后在你的 React 应用中像这样使用:

<Spinner />
