PlayBook中的绝对路径问题

[Bird]

我使用HTML5开发应用，想在网页中写死一个资源的绝对路径，他在sdcard的music目录下面，请问我怎么获得他的绝对路径呢？就像电脑中的d:\test.mp3一样，谢谢

<script type="text/javascript">
var dirs = blackberry.io.dir.appDirs;

alert('Application storage folder path:' + dirs.app.storage.path);

// access_shared permission must be added in order to access shared folder
for (var subfolder in dirs.shared) {
alert(subfolder + '.path:' + eval('dirs.shared.' + subfolder + '.path'));
}

var musicDir = dirs.shared.music.path;
alert('Music folder path:' + musicDir);
</script>
