如何使用类组件在react本机中传递参数并将其传递到另一个组件中

import React, { Component } from 'react';

class ParentComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      name: 'John',
    };
  }

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

export default ParentComponent;

import React from 'react';

const ChildComponent = (props) => {
  return <p>{props.name}</p>;
};

export default ChildComponent;

// 父组件
import React, { Component } from 'react';
import ChildComponent from './ChildComponent';

class ParentComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      name: 'John',
    };
  }

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

export default ParentComponent;

// 子组件
import React from 'react';

const ChildComponent = (props) => {
  return <p>{props.name}</p>;
};

export default ChildComponent;
