Question

此代码播放Youtube视频。该文件使用FlashBuilder中的“调试”或“运行”按钮，但在从Web服务器或“导出发行”文件夹中播放时出现错误：当第二个视频运行时，第一个视频中的音频会继续播放。如何卸载第一个音频？

第二次按键点击停止第一个视频/音频的解决方案是：

在代码中使用以下内容从swfloader卸载第一个视频：

<fx:Script>
        <![CDATA[
            import mx.controls.SWFLoader;

        private var swfLoader:SWFLoader;
        [Bindable] public var  videoToPlay:String
        public function playVideo(videoNum:int):void
        {
            if(swfLoader)
            {
                swfLoader.autoLoad = false;
                swfLoader.unloadAndStop();
//              swfLoader.autoLoad = true; 
                hg.removeElement(swfLoader);             
                SoundMixer.stopAll();
            }
            var videoAddress:String 
            if(videoNum == 1){
            videoAddress = "m2dg6teC7fg";
            }else{
            videoAddress = "0QRO3gKj3qw";               
            }
            videoToPlay = "https://www.youtube.com/v/VIDEO_ID?v=" + videoAddress;    
            play();
        }               
        public function play():void
        {
            swfLoader = new SWFLoader();
            swfLoader.y = 100;
            swfLoader.load(videoToPlay);       
            hg.addElement(swfLoader);
        }

        ]]>
    </fx:Script>

我已编辑下面的代码，这适用于您的问题（我测试过我的一面）。尝试一下，让我知道它有效吗？
