关于前端:React-中事件总线使用流程

依赖库events

eventBus.js

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

公布组件

import Bus from '../../EventBus';<Button type='primary' onClick={ () => { Bus.emit('changeSiblingsData', count) }}>提交</Button>

订阅组件

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