JS HTML5 音乐天气播放器(Ajax获取天气信息)


Posted in Javascript onMay 26, 2013

晚上要考软件工程,实在不想复习。写个播放器吧,这个只是个用来学习的小Demo,众多不完善之处,下面贴出源代码,如果要转载,请加上版权声明

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)
