我正在设计一个使用JavaScript(jQuery)和HTML5的音乐播放器,以及Flash AS3。基本上我想要做的是能够点击HTML控件元素并让他们与flash交互以播放/暂停和跳过播放列表中的曲目(由JavaScript读取的播放列表JSON文件,将文件ID传递给AS3,AS3读取另一个获取URL的JSON文件,然后播放音频)
这使我只能使用Flash播放音频,因此无论HTML5浏览器支持如何,都可以创建相同的用户体验。
我假设我必须'监听'AS3中的事件,但是如何在JS中参与这些事件以及对AS3中的事件做出反应的任何指示都将是一个很大的帮助!

要在JavaScript和ActionScript之间进行通信,可以使用ExternalInterface API:
作为您想要做的事情的替代方案,您可以使用SoundManager 2播放音频,并使用JavaScript完成所有自己的编程:
“使用HTML5和Flash,SoundManager 2提供可靠的跨平台 单个JavaScript API下的音频。“

我对这个问题有了答案,但在我完成之前接受了答案。无论如何它是:
Main.as(文档类):
package
{
import flash.display.Sprite;
import flash.events.Event;
import flash.external.ExternalInterface;
import flash.media.Sound;
import flash.media.SoundChannel;
import flash.net.URLRequest;
public class Main extends Sprite
{
private var _sound:Sound;
private var _soundChannel:SoundChannel;
public function Main():void
{
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}// end function
private function init(e:Event = null):void
{
removeEventListener(Event.ADDED_TO_STAGE, init);
if (ExternalInterface.available)
{
ExternalInterface.addCallback("loadSound", loadSound);
ExternalInterface.addCallback("stopSounds", stopSounds);
}// end if
}// end function
private function loadSound(url:String):void
{
_sound = new Sound();
_sound.load(new URLRequest(url));
if (_soundChannel) _soundChannel.stop();
_soundChannel = _sound.play();
}// end function
private function stopSounds():void
{
_soundChannel.stop();
}// end function
}// end class
}// end package
