Question

我正在尝试从我的Player.as发送自定义YouTubeEvent并希望我的Main.as会监听并创建视频播放器......显然我的eventHandler无法捕捉事件来创建视频播放器..... ..我的flex调试模式是如此搞砸我甚至无法使用它...我的代码如下..我非常感谢任何回复或帮助......

我的自定义活动..

package com.youtube.events {
    import flash.events.Event;

    public class YouTubeEvent extends Event{

        public static const PLAYER_READY:String="PLAYER_READY";

        public function YouTubeEvent(type:String){
            super(type);
        }
    }

}

My Main.as

public class SearchYoutube extends Sprite
{
      private var videoPlayer:Player;

  public function SearchYoutube()
    {

    /*********************Load Video Player****************************/
        loadPlayer();
    }


    private function loadPlayer():void{
    videoPlayer= new Player();
    videoPlayer.addEventListener(YouTubeEvent.PLAYER_READY, playerReady);

            //playReady would never be excuted....
    }

            private function playerReady(event:YouTubeEvent):void{
    videoPlayer.createPlayer();   //This handler would never be executed...
    addChild(videoPlayer);       //This handler would never be executed...
    }

}

Player.as

//only show part of codes here
public function Player(){

}
public function createPlayer():void{

    _loader = new Loader();
    _loader.contentLoaderInfo.addEventListener(Event.INIT, onLoaderInit);


    }

    private function onLoaderInit(event:Event):void {

    _loader.content.addEventListener("onReady", onPlayerReady);

            }


    private function onPlayerReady(event:Event):void {

    dispatchEvent(new YouTubeEvent(YouTubeEvent.PLAYER_READY));

    }

Answer 1

调用YouTubeEvent.PLAYER_READY后，

createPlayer()会被调度一段时间。您应该在createPlayer()之后致电videoPlayer.addEventListener(YouTubeEvent.PLAYER_READY, playerReady)：

private function loadPlayer():void
{
    videoPlayer= new Player();
    videoPlayer.addEventListener(YouTubeEvent.PLAYER_READY, playerReady);
    videoPlayer.createPlayer();
}
