我有改變的代碼在你的應用程序，請檢查在這裏Demo

import React from 'react' 
import {render} from 'react-dom' 
import { CSSTransitionGroup } from 'react-transition-group' 



class SendData extends React.Component{ 
    constructor(props) { 
    super(props); 
    this.state = { 
     images: [ 
     'http://via.placeholder.com/350x150', 
     'http://via.placeholder.com/350x151' 
     ], 
     currentImage: 0 
    }; 
    this.fadeImage=this.fadeImage.bind(this); 
    } 
    fadeImage(e) { 
    e.preventDefault(); 
    this.setState({currentImage: (this.state.currentImage + 1) % this.state.images.length}) 
    } 
    render() 
    { 

    return(
     <FadeImage images={this.state.images} currentImage={this.state.currentImage} fadeImage={this.fadeImage}/> 
    ) 
    } 
} 
class FadeImage extends React.Component { 

    constructor(props) { 
    super(props); 
    } 



    render() { 
    return (
      <div className="image"> 
     <CSSTransitionGroup 
     transitionName="example" 
     transitionEnterTimeout={300} 
     transitionLeaveTimeout={300} 
     > 
      <section> 
      <button className="button" onClick={this.props.fadeImage.bind(this)}>Click!</button> 
      <img src={this.props.images[this.props.currentImage]}/></section> 
     </CSSTransitionGroup> 
     </div> 
    ); 
    } 
    } 


render(<SendData />, document.querySelector('#app'))
