import React, { Component } from 'react';

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

  handleClick = () => {
    this.setState(prevState => ({
      highlighted: !prevState.highlighted
    }));
  }

  render() {
    const { highlighted } = this.state;
    const divClassName = highlighted ? 'highlighted' : '';

    return (
      <div className={divClassName} onClick={this.handleClick}>
        {/* 内容 */}
      </div>
    );
  }
}

export default HighlightDiv;
