无法使动画与AMP和React一起使用

Question

我正在一个React AMP项目中，我需要使用AMP做一些微妙的动画，以便在滚动窗口时显示和隐藏按钮。

因为AMP动画标签期望<amp-animation>的子级中有一个对象，但React不允许该对象作为其子级。

这是我尝试使用的代码：

import React from 'react';
const showAnim = {
  "duration": "200ms",
  "fill": "both",
  "iterations": "1",
  "direction": "alternate",
  "animations": [
    {
      "selector": "#download-button",
      "keyframes": [
        { "opacity": "1", "visibility": "visible" }
      ]
    }
  ]
}
const hideAnim = {
  "duration": "200ms",
  "fill": "both",
  "iterations": "1",
  "direction": "alternate",
  "animations": [
    {
      "selector": "#download-button",
      "keyframes": [
        { "opacity": "0", "visibility": "hidden" }
      ]
    }
  ]
};
export default class Animate extends React.Component {

  componentDidMount() {
    window.addEventListener('scroll', this.onScroll)
  }

  onScroll = () => {
    console.log('scrolling')
  }

  renderShowAnimation = () => <amp-animation id="showAnim" layout="nodisplay" src="">
    <script type="application/json">
      {showAnim}
    </script>
  </amp-animation >;

  renderHideAnimation = () => <amp-animation id="showAnim" layout="nodisplay">
    <script type="application/json">
    {hideAnim}
    </script>
  </amp-animation >;


  render() {
    return (
      <main onScroll={this.onScroll} >
        <div>
         {this.renderShowAnimation()}
          {this.renderHideAnimation()}
              <div className="download-button" id="download-button" role="button">
                Download
                <amp-position-observer
                  on="enter:hideAnim.start; exit:showAnim.start"
                  layout="nodisplay">
                </amp-position-observer>
              </div>
        </div>
      </main>
    )
  }
}

现在，当我尝试运行该应用程序时，出现以下错误：

Objects are not valid as a React child (found: object with keys {duration, fill, iterations, direction, animations}).

我也尝试放置一个onScroll事件，但它在AMP中也不起作用。如果有人使用辅助词或我的代码有问题，请提出建议。
