React -如何在回调函数中将参数从子对象传递到父对象(onClick)

// 父组件
class ParentComponent extends React.Component {
  handleChildData = (data) => {
    // 处理子组件传递的数据
    console.log(data);
  }

  render() {
    return (
      <div>
        <ChildComponent onChildData={this.handleChildData} />
      </div>
    );
  }
}

// 子组件
class ChildComponent extends React.Component {
  handleClick = () => {
    const data = 'Hello from child component';
    // 调用父组件传递的回调函数，并将数据作为参数传入
    this.props.onChildData(data);
  }

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