我玩玩而已的新的YouTube AS3 API，但卡住了。这是 多远，我得到了（从看他们的样code）。

I'm goofing around with the new youtube as3 API but got stuck. This is how far i got (from looking at their sample code).

pastie/656088

public class Main extends Sprite { Security.allowDomain("*"); private var player:Object; private var loader:Loader; public function Main():void { if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event = null):void { removeEventListener(Event.ADDED_TO_STAGE, init); loader = new Loader(); loader.contentLoaderInfo.addEventListener(Event.INIT, onLoaderInit); loader.load(new URLRequest("www.youtube/apiplayer?version=3")); } private function onLoaderInit(e:Event):void { addChild(loader); loader.contentLoaderInfo.addEventListener("onReady", onPlayerReady); loader.contentLoaderInfo.addEventListener("onError", onPlayerError); loader.contentLoaderInfo.addEventListener("onStateChange", onPlayerStateChange); loader.contentLoaderInfo.addEventListener("onPlayerQualityChange", onVideoPlaybackQualityChange); } private function onPlayerReady(e:Event):void { trace("Player ready: " + Object(e).Data); } private function onPlayerError(e:Event):void { trace("Player error: " + Object(e).Data); } private function onPlayerStateChange(e:Event):void { trace("Player state: " + Object(e).Data); } private function onVideoPlaybackQualityChange(e:Event):void { trace("Video quality: " + Object(e).Data); } }

我真的不知道是什么，下一步就是。我没有得到任何错误，并没有被跟踪。我是pretty的肯定，我的事件没有正确实施。

I don't really know what the next step is. I get no errors and nothing gets traced. I'm pretty sure that my events are not implemented correctly.

更新： 我跟着Amarghosh的回答，这样做，而不是：

Update: I followed Amarghosh's answered and did this instead:

private function onLoaderInit(e:Event):void { player = Sprite(loader.content); addChild(player); player.addEventListener("onReady", onPlayerReady); player.addEventListener("onError", onPlayerError); player.addEventListener("onStateChange", onPlayerStateChange); player.addEventListener("onPlayerQualityChange", onVideoPlaybackQualityChange); }

现在的onPlayerReady和onStateChange事件，火灾，但我得到的错误。当跟踪对象（E）。数据我得到这个错误

Now the onPlayerReady and the onStateChange events fires but i get errors. When tracing Object(e).Data i get this error

的ReferenceError：错误＃1069：该属性的数据，未发现com.google.youtube.event.ExternalEvent并没有标准值 （瑞典stranslated） 当更改到对象（e.target）。数据它的踪迹不确定和对象（e.target）跟踪[对象SwfProxy]。

ReferenceError: Error #1069: the property Data was not found for com.google.youtube.event.ExternalEvent and there is no standard value. (stranslated from swedish) When changing to Object(e.target).Data it traces "undefined" and Object(e.target) traces [object SwfProxy].

如果我尝试 player.loadVideoById（uad17d5hR5s）; 我得到这个错误：

If i try player.loadVideoById("uad17d5hR5s"); i get this error:

1061：雪碧

推荐答案

对不起，所有图书馆的困惑，我想我已经回答了你的其他错误，但。当你这样做雪碧（loader.content）你力投玩家是一个精灵，因为你想要的API的方法我会建议使用一个普通的旧对象，因为它不会抱怨无类型的方法：

sorry for all the library confusion, I think I have the answer to your other error though. When you do this Sprite(loader.content) you 'force' cast the player to be a sprite, because you want methods of the api I would recommend using a plain old object, because it won't complain about untyped methods:

// No particluar type var player:Object; private function onLoaderInit(e:Event):void { player = loader.content; addChild(player as DisplayObject); var dispatcher:IEventDispatcher = player as IEventDispatcher; dispatcher.addEventListener("onReady", onPlayerReady); dispatcher.addEventListener("onError", onPlayerError); dispatcher.addEventListener("onStateChange", onPlayerStateChange); dispatcher.addEventListener("onPlayerQualityChange", onVideoPlaybackQualityChange); }
