JQuery网页音乐播放器制作

    IT168 有一篇关于Jquery制作网页播放器的文章()，这里引用了他的Div+css表现形式，再此表示感谢。不过他那个是用ezSQL连接数据库，并且播放音乐是随机从数据库中选择一首。这对于网站开发来说是不够的，在下不才，稍做更改，以实用于程序系统。

    相对于原系统主要做了以下更改：

1、数据库访问采用经典的php+mysql连接方式；

2、音乐播放采用按需播放，通过网页地址动态获取音乐id。

 

演示地址：

 

主要代码如下：

play.php:

此代码中加入了js动态获取url中数据的函数和jquery.get方法，也是更改关键所在。
