界面较为简单，支持播放列表 。
建立播放列表的步骤为：
1)在文本框中输入媒体资源的地址，可以是HTTP地址，相对地址和绝对地址
2)点击“添加到媒体列表”按钮，将媒体资源信息放到媒体列表中
3)在媒体列表中，点击“添加”链接，将媒体加入到播放列表中
4)重复若干遍，加入所有歌曲
5)点击“播放选中的歌曲“，就开始播放 播放列表中的所有打勾的媒体文件
完整代码如下：
<script language="JavaScript"> function el(objname) { return document.getElementById(objname); } //增加一首歌到播放器列表，这样，播放器放完一首歌之后，会继续放下一首 function addmedia(url) { // 取得当前的播放列表 var playlist=Player.currentPlaylist;//新建一个指定URL的Media。 var currMedia = Player.newMedia(url); //把新建的Media item添加到播放器列表 playlist.appendItem(currMedia); } function clearlist() { //Player.currentPlaylist.count返回列表中的歌曲数量 while(Player.currentPlaylist.count>0) { var item =Player.currentPlaylist.item(Player.currentPlaylist.count-1); Player.currentPlaylist.removeItem(item); //从播放列表中删除项 } } //清空播放列表 function clearPlaylist() { clearlist(); var l_tb = el("tabPlayList"); var row_len = l_tb.rows.length; for(var i = 0; i < row_len; i++) l_tb.firstChild.removeChild(l_tb.firstChild.childNodes[0]); } //清空媒体列表 function clearMedialist() { var l_tb = el("tabMediaList"); var row_len = l_tb.rows.length; for(var i = 0; i < row_len; i++) l_tb.firstChild.removeChild(l_tb.firstChild.childNodes[0]); } //播放选中的歌曲 function addSeletedSongToPlayList() { clearlist();

if(check.checked==true) { addmedia(songname); } } SetPlayMode(el("setplay").options[el("setplay").selectedIndex].value) Player.controls.play(); //让播放器开始播放 } //添加文本输入框中的url到播放列表 function addUrlToList() { //addmedia(document.getElementById("songURL").value );
