ajax中文问题
var strValue = music.value;    //歌曲的路径
        alert(strValue);          //    E:/music/张敬轩-分手前的雨天.mp3
        var url = 'getLyric.jsp';
        var strParams = 'q=' + strValue; //传值
        //发送
      var loader1 = new
        net.ContentLoader(url,FillDropDown,null,
                    "POST",strParams);

getLyric.jsp
//取值
String strQuery =new String(request.getParameter("q").getBytes("iso-8859-1"),"GB2312");//出乱码

了...

AJAX只支持UTF-8?
