function animation () { var seamless_container = document.getElementsByClassName(

下面是将给定代码用TypeScript重新编写的示例：

import React, { useEffect } from 'react';

const AnimationComponent: React.FC = () => {
  useEffect(() => {
    const seamlessContainers = document.getElementsByClassName("cl-seamless-container");

    for (let i = 0; i < seamlessContainers.length; i++) {
      const seamlessContainer = seamlessContainers[i] as HTMLElement;

      if (seamlessContainer.children.length > 0) {
        let seamlessSub = seamlessContainer.children[0] as HTMLElement;
        seamlessContainer.style.maxHeight = "100px";
        let scrollSpeed = 30;
        seamlessSub.style.animation = `cl-scrolling ${scrollSpeed}s infinite linear`;

        // 复制一份完全相同的列表，实现无缝滚动
        seamlessContainer.innerHTML += seamlessContainer.innerHTML;
      }

      // 监听鼠标移入事件，暂停动画；同时鼠标移出，继续动画
      const pauseAnimation = () => {
        if (!seamlessContainer.classList.contains("pause")) {
          seamlessContainer.classList.add("pause");
        } else {
          seamlessContainer.classList.remove("pause");
        }
      };

      seamlessContainer.addEventListener("mouseenter", pauseAnimation);
      seamlessContainer.addEventListener("mouseleave", pauseAnimation);
    }
  }, []);

  return <div>Animation Component</div>;
};

export default AnimationComponent;

请注意，上述代码假设在React组件中使用，并通过useEffect来触发动画效果。其中，我们使用了类型断言（as）来将元素转换为HTMLElement类型，以便访问和修改其属性。还需要在适当的位置添加CSS样式以支持动画效果。

请根据您的具体需求和页面结构进行适当的调整。希望这个示例对你有所帮助！
