JS HTML5 音乐天气播放器(Ajax获取天气信息)

Posted in Javascript onMay 26, 2013

PS:因为Ajax涉及到跨域获取天气信息，有两个版本，一个是直接跨域，IE10支持，其他的浏览器要改配置。另一个是服务器端的weather.php，获取天气信息返回json。
weather.php就不写了，里面的对应路径存放对应的文件

演示地址:
http://569375.ichengyun.net/fm/

实现功能：
音乐播放，进度调节（滑动模块），音量条件，音乐随机选择，背景图片，图片预加载，音乐预加载，天气Ajax获取
音乐列表使用的json处理（也可以理解是hash表）
