React:使用Scroll库上的动画有条件地呈现CSS类

import React, { Component } from 'react';
import Scroll from 'scroll';

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      isScrolled: false
    };
  }

  componentDidMount() {
    Scroll.addListener(() => {
      // 根据滚动的位置和条件，更新isScrolled状态变量的值
      if (window.scrollY > 100 && someCondition) {
        this.setState({ isScrolled: true });
      } else {
        this.setState({ isScrolled: false });
      }
    });
  }

  render() {
    const { isScrolled } = this.state;
    return (
      <div className={isScrolled ? 'scrolled' : ''}>
        {/* 根据isScrolled状态变量的值，有条件地呈现CSS类 */}
        {/* 其他组件内容 */}
      </div>
    );
  }
}

export default MyComponent;
