 var songs:String= "part" + randnum + ".mp3";  
 sound.load(new URLRequest("file:///D:/parts/"+songs));
 soundChannel=sound.play();
 soundChannel.addEventListener(Event.SOUND_COMPLETE,playrandomsong);
 }
 function playrandomsong(e:Event)
 {
 playsong();
 }

这是我使用的 Actionscript 3 代码，用于从本地目录的数组中随机播放 MP3。它有效，但我的问题是我使用它的应用程序较旧并且不支持 AS3 - 仅支持 AS2 和更早版本。有谁知道这个代码的等价物是什么？

AS2中没有导入的包，没有、、、Event类SoundChannel，URLRequest类Sound接口不同。

未经测试：

var sound:Sound;
var randnum:Number;

function playsong()
{
    randnum = Math.floor(Math.random() * 127);
    var songs:String = "part" + randnum + ".mp3";  

    sound = new Sound();
    sound.onSoundComplete = playrandomsong;
    sound.loadSound("file:///D:/parts/" + songs, true);
}

function playrandomsong()
{
    playsong();
}
