onClick在基于react类的组件中不起作用

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.handleClick = this.handleClick.bind(this);
  }

  handleClick() {
    // 处理点击事件的逻辑
  }

  render() {
    return <button onClick={this.handleClick}>点击我</button>;
  }
}

class MyComponent extends React.Component {
  handleClick() {
    // 处理点击事件的逻辑
  }

  render() {
    return <ChildComponent onClick={this.handleClick} />;
  }
}

class ChildComponent extends React.Component {
  render() {
    return <button onClick={this.props.onClick}>点击我</button>;
  }
}
