从子React导航器屏幕的父组件中运行函数，不带redux

// 父组件
import React from 'react';
import ChildComponent from './ChildComponent';

class ParentComponent extends React.Component {
  handleClick = () => {
    console.log('执行函数');
  }

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

export default ParentComponent;

// 子组件
import React from 'react';

class ChildComponent extends React.Component {
  render() {
    return (
      <div>
        <button onClick={this.props.onClick}>点击执行函数</button>
      </div>
    );
  }
}

export default ChildComponent;
