我们有下面的反应组件，当点击图像时，我们正在开始从soundcloud流式传输歌曲。但是当歌曲被列出时，所有歌曲都在同一时间播放..任何建议都值得赞赏..

你应该为此创建一个子组件，每个组都有自己的onClick。目前，您为每一行调用相同的函数，并在渲染时同时调用它们。

var TableRows = React.createClass({
    render: function(){
        var track = this.props.track;
        return (
            <tr ref="trackRow">
                <td>{track.title}</td>
                <td><img onClick={ this.playTrack } className="images" src={track.artwork_url}/></td>
            </tr>
        );
    },
    playTrack: function(){
        // use the track in your props aka... this.props.track

    }
});

然后将您的foreach更改为map并执行此操作

this.props.data.map(function(track, i) {
    rows.push(<TableRows track={track} key={i} />);
});

注意：这是对你的行渲染的清理......如果你注意到你正在渲染它时调用playTrack函数... onClick={context.playTrack(track)}实际上是调用函数然后那里..所以你我想不要用括号调用它，并为每一行使用一个组件，这样你就可以访问道具中的轨道了。
