handleClick(item, e) {

let file='http://localhost:8088/myServer/mybase/mp3/'+item.title+'.mp3';

this.setState({mp3file: file});

this.setState({nowitem: item.id});

nextplay = (e) =>{

this.setState({nowitem: id+1});

this.setState({nowitem: item.title});

}

render(){

return (

<div>

<tr>

</tr></thead>

<tbody>

{

this.state.songs.map((item, index)=>{

return(

<td>

<a href="#" onClick={this.handleClick.bind(this, item)} style={{textDecoration:'none'}}><img src={require('../../images/play.png')} width="20" height="20" style={{marginRight:'10px'}}/>{item.title}</a>

</td>

<td>{item.singer}</td>

<td>{item.album}</td>

<td>{item.title}</td>

</tr>

)

})

}</tbody>

</table>

<div >

<button onClick={() => {this.nextplay()}} style={{position:'absolute', top:300, left:60, width:50,height:50,borderRadius:'30%',border: '1px solid #d5d5d5',fontSize:'13px'}}>下一曲</button>

</div>

)

}

mp3歌曲是从后台提取的，以后会做成动态，即数据库提取数据。

还想做一个单曲循环的功能但是还在研究。

本实例还是有bug的，比如说删除了该歌曲，上一曲播放点击下一曲，被删除的仍然可以播放。
