Question

我有五个按钮，其中包含五首歌曲。然后我有一个播放按钮和停止按钮。现在当我点击一个歌曲按钮然后点击播放按钮时，相应的歌曲应该播放。我按下停止按钮，歌曲应该停止。再次选择不同的歌曲并点击播放按钮，指定的歌曲应该播放。我使用下面给出的代码，但我无法得到输出。请帮帮我...... !!

sng1.addEventListener(MouseEvent.CLICK, mclick);
sng2.addEventListener(MouseEvent.CLICK, mclick);
sng3.addEventListener(MouseEvent.CLICK, mclick);
sng4.addEventListener(MouseEvent.CLICK, mclick);
sng5.addEventListener(MouseEvent.CLICK, mclick);
var url:String;
function mclick(e:MouseEvent)
{
        //private var url:String = "FIFA Theme song.mp3";
        if(e.currentTarget.name == "sng1")
        {
             url="Ippadi Mazhai.mp3";
        }
        else if (e.currentTarget.name == "sng2")
        {
             url = "06 Gore Gore.mp3";
        }
        else if (e.currentTarget.name == "sng3")
        {
             url = "FIFA Theme song.mp3";
        }
        else if (e.currentTarget.name == "sng4")
        {
             url = "babe.mp3";
        }
        else if (e.currentTarget.name == "sng5")
        {
             url = "fast_and_furious_5.mp3";
        }

}
        public class audio extends Sprite{
        private var song:SoundChannel;
        private var soundFactory:Sound;
        public function audio() {
            var request:URLRequest = new URLRequest(url);

            soundFactory = new Sound();
            soundFactory.addEventListener(Event.COMPLETE, completeHandler);
            soundFactory.addEventListener(Event.ID3, id3Handler);
            soundFactory.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
            soundFactory.load(request);
            song = soundFactory.play();
            plybtn.addEventListener(MouseEvent.CLICK, plClick);
            stpbtn.addEventListener(MouseEvent.CLICK, stpClick);
        }
        private function completeHandler(event:Event):void {
            trace("completeHandler: " + event);
        }

        private function id3Handler(event:Event):void {
            trace("id3Handler: " + event);
        }

        private function ioErrorHandler(event:Event):void {
            trace("ioErrorHandler: " + event);
        }

        private function progressHandler(event:ProgressEvent):void {
            trace("progressHandler: " + event);
        }
        private function plClick(evt:MouseEvent)
        {
             song = soundFactory.play();
        }
        private function stpClick(evt:MouseEvent)
        {
             song.stop();
        }

    }

}

Answer 1

仅仅更改url以使以下代码正常工作是不够的，您需要一个new audio()语句来实际加载该声音并播放它。一种正确的方法是，如果您使用所有5个不同的URL初始化所有5个audio个对象，它们都将处于停止状态，然后显示它们并单击它们的按钮。
