        /*
            1.歌词文件不能是默认编码(记事本文件和lrc文件默认为ANSI编码) 只需要改为 UTF-8或

者GB2312,否则乱码
            2.歌曲因为没有算毫秒差距,可能出现细微误差
            3.因为网页同源策略的原因,外部直接打开html文件只能用firefox访问,
               不能进行跨域访问,如果不使用文件读取可以在任意地方打开.
            4.因为ajax识别原因,会把空格当做分割内容,即歌词文件名不能有空格
            5.因为js对文件操作以及ajax请求存在诸多默认限制,若以类似方法在winfrom asp等中很

多问题都会得到解决.
            6.setTimeout()和setInterval(),在浏览器窗口非激活的状态下会停止工作或者以极慢的

速度工作。目前我已知就IE不会有这种问题。
