我是 AS3 的新手，我正在构建一个完整的 flash 网站，我尝试在其中包含背景音乐和播放、暂停和停止按钮（播放和暂停是同一个按钮）。问题是音乐播放器在页面加载时自动播放，当我点击我网站的 HOME 按钮时，音乐再次播放并与首先播放的音乐重叠，所以我该怎么办..提前谢谢

stop();

function goHome (e:MouseEvent):void{
gotoAndStop("HOME");
}
home_btn.addEventListener(MouseEvent.CLICK, goHome);

function goAbout (e:MouseEvent):void{
gotoAndStop("COMPANY");
}
company_btn.addEventListener(MouseEvent.CLICK, goAbout);

function goTestimony (e:MouseEvent):void{
gotoAndStop("TESTIMONY");
}
news_btn.addEventListener(MouseEvent.CLICK, goTestimony);

function goProduct (e:MouseEvent):void{
gotoAndStop("PRODUCT");
}
product_btn.addEventListener(MouseEvent.CLICK, goProduct);

function goContact (e:MouseEvent):void{
gotoAndStop("CONTACT");
}
contacts_btn.addEventListener(MouseEvent.CLICK, goContact);

//imports the necessary as events
import flash.events.Event
import flash.events.MouseEvent;

var isPlaying:Boolean = new Boolean();
var pausePosition:Number = new Number();

//Create an instance of the Sound class
var soundClip:Sound = new Sound();
//Create a new SoundChannel Object
var sndChannel:SoundChannel = new SoundChannel();

//Load sound using URLRequest
soundClip.load(new URLRequest("thousandyears.mp3"));

//Create an event listener that wll update once sound has finished loading
soundClip.addEventListener(Event.COMPLETE, onComplete, false, 0, true);

controller.addEventListener(MouseEvent.MOUSE_DOWN, btnPressController, false, 0, true);
stop_btn.addEventListener(MouseEvent.MOUSE_DOWN, btnPressStop, false, 0, true);

function onComplete(evt:Event):void {
    //Play loaded sound
    sndChannel = soundClip.play();
    isPlaying = true;
}

function btnPressController(evt:MouseEvent):void
{
    switch(isPlaying)
    {
        case true:
            controller.gotoAndStop(2);
            pausePosition = sndChannel.position; 
            sndChannel.stop();
            isPlaying = false;
        break;
        case false:
            controller.gotoAndStop(1);
            sndChannel = soundClip.play(pausePosition);
            isPlaying = true;
        break;
    }
}

function btnPressStop(evt:MouseEvent):void
{
    pausePosition = 0;
    sndChannel.stop();
    controller.gotoAndStop(2);
    isPlaying = false;
}

此代码在第 1 帧中吗？第 1 帧是否标记为“HOME”？

如果是这样，我会在时间线的开头添加一个新帧（新帧 1）并将代码移入其中。这样，代码仍然在第 1 帧中，“HOME”帧将在第 2 帧中，依此类推。

您需要稍微更新您的代码：

替换stop()为gotoAndStop('HOME');
