如何获得音频元素？

它可以使用组件引用进行工作：

var AudioPlayer = React.createClass({    componentDidMount: function () {        console.info('[AudioPlayer] componentDidMount...');        this.props.el = React.findDOMNode(this.refs.audio_tag);        console.info('audio prop set', this.props.el);    },    render: function() {        console.info('[AudioPlayer] render...');        return ( <audio ref="audio_tag" src="/static/music/foo.mp3" controls autoplay="true"/>        );    }});
