在react JS中使用从子对象传递到父对象的数据更新Firebase对象

import firebase from 'firebase/app';
import 'firebase/database';

class ParentComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      firebaseObject: null,
    };
  }

  componentDidMount() {
    // 初始化Firebase
    const firebaseConfig = {
      // Firebase配置信息
    };
    firebase.initializeApp(firebaseConfig);

    // 获取Firebase对象并更新状态
    const firebaseObjectRef = firebase.database().ref('path/to/firebaseObject');
    firebaseObjectRef.on('value', (snapshot) => {
      const firebaseObject = snapshot.val();
      this.setState({ firebaseObject });
    });
  }

  render() {
    return (
      <div>
        <ChildComponent firebaseObject={this.state.firebaseObject} />
      </div>
    );
  }
}

class ChildComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      newData: '',
    };
  }

  handleDataUpdate = () => {
    const { firebaseObject } = this.props;
    const { newData } = this.state;

    // 更新Firebase对象
    firebaseObject.child('data').set(newData);
  }

  handleInputChange = (event) => {
    this.setState({ newData: event.target.value });
  }

  render() {
    return (
      <div>
        <input type="text" onChange={this.handleInputChange} />
        <button onClick={this.handleDataUpdate}>更新Firebase对象</button>
      </div>
    );
  }
}
