IOS版添加phonegap--音乐播放器插件教程

一:HTML实现方法

       

正在播放：

        

• 歌曲名


• 歌曲名

二:注意的是上面播放器是需要图标来支持的，根据自己的风格自己写CSS样式。


三:添加music.js文件。
var my_media = null;//当前音乐对象
var mediaTimer = null;
var is_play = null;//当前播放对象，1播放，0暂停
var now_play = null;//当前播放的音乐地址
var now_div = null;//当前操作的滚动条所在的div
var txt = null;
