Reactjs -如何从一个组件(Inputbox)获取输入并在其他组件中使用它

class Inputbox extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      inputValue: ''
    };
  }

  handleInputChange(event) {
    this.setState({ inputValue: event.target.value });
  }

  render() {
    return (
      <input
        type="text"
        value={this.state.inputValue}
        onChange={this.handleInputChange.bind(this)}
      />
    );
  }
}

class OtherComponent extends React.Component {
  render() {
    return (
      <div>
        <p>输入的值是：{this.props.inputValue}</p>
      </div>
    );
  }
}

class ParentComponent extends React.Component {
  render() {
    return (
      <div>
        <Inputbox />
        <OtherComponent inputValue={this.state.inputValue} />
      </div>
    );
  }
}
