React 中事件总线使用流程

依赖库events

eventBus.js

import { EventEmitter } from 'events';
export default new EventEmitter();

发布组件

import Bus from '../../EventBus';
 { Bus.emit('changeSiblingsData', count) }}>提交

订阅组件

import Bus from '../../EventBus';
Bus.addListener('changeSiblingsData', (count)=> {
    alert(count); 
});
