原创: 做一款属于自己风格的音乐播放器 (HTML5的Audio新特性)

灵感的由来是前些天看到了博： http://www.cnblogs.com/li-cheng 的首页有一个很漂亮的播放器，感觉很不错，是用Flex做的Flash播放器。

于是我也便想到了，自己也来来弄个玩玩。

所以利用1天的时间，通过收集整理，做了一款自己专属的播放器!

播放器实现了以下功能操作：
1：播放、暂停
2：快进、快退
3：上一曲、下一曲
4：单曲循环

效果如下：

奉献JS源码如下：

(function ($) {
    $.fn.Html5Player = function() {
            //获取音频API 
            var audio = $('body').find('audio').get(0);
