（1）ES6的使用 （https://github.com/brigand/react-mixin）

　　下载依赖包

npm i react-mixin --save

（2）导入react-mixin包

import ReactMixin from 'react-mixin'

（3）创建js文件 MixinLog.js

const MixinLog = {
  log(){
    console.log('111')
  }
};

export default MixinLog;

（4）使用MixinLog

import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
import ReactMixin from 'react-mixin';
import MixinLog from './components/MixinLog';

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {date: new Date()};
  }

  handle() {
    Mixin.log();
  }

  render() {
    return (
      

        

          
          
Welcome to React
        
        
{this.state.date.toLocaleTimeString()}
      
    );
  }
}

ReactMixin(App.prototype, MixinLog)
