React -删除事件侦听器(onmousedown -> onmousemove)

import React, { Component } from 'react';

class MyComponent extends Component {
  componentDidMount() {
    document.addEventListener('mousedown', this.handleMouseDown);
    document.addEventListener('mousemove', this.handleMouseMove);
  }

  componentWillUnmount() {
    document.removeEventListener('mousedown', this.handleMouseDown);
    document.removeEventListener('mousemove', this.handleMouseMove);
  }

  handleMouseDown = (event) => {
    // 处理鼠标按下事件
  }

  handleMouseMove = (event) => {
    // 处理鼠标移动事件
  }

  render() {
    return (
      <div>
        {/* 组件的内容 */}
      </div>
    );
  }
}

export default MyComponent;
