Javascript 包装YouTube iFrame API的Angular服务-loadVideoById（）引发异常

Cdoe：

调用“setVideo”后出现的错误如下：

TypeError:对象#没有方法“loadVideoById”
在Object.ytplayer.setVideo(http://localhost:8000/js/youtube.js:36:23)
at Object.fn(http://localhost:8000/js/controllers.js:2939:33)
在h.$get.h.$digest(http://localhost:8000/lib/angular/1.2.5/angular.min.js:98:396)
在h.$get.h.$apply(http://localhost:8000/lib/angular/1.2.5/angular.min.js:101:157)
在HTMLInputElement.h(http://localhost:8000/lib/angular/1.2.5/angular.min.js:123:493)
在HTMLInputElement.x.event.dispatch(http://localhost:8000/js/jquery.min.js:5:14129)
在HTMLInputElement.x.event.add.v.handle(http://localhost:8000/js/jquery.min.js:5:10866)

注销该对象会使我：

Y{b:wb，a:iframe#ytPlayer，o:null，closure_uid_613255056:2，u:2…}
D:反对
a:我是一名球员
b:wb
结案日期(613255056):2
d:43
g:N
h：“玩家”
i:反对
k:反对
o:空
s:数组[0]
t:是的
u:2
__原型：c

非常感谢您的帮助

您的日志数据表明YT播放器尚未初始化。在代码中的什么地方调用loadPlayer函数？如果您可以提供它可能有助于调试。我将发布它，感谢您的评论，也许问题是我在1个控制器中初始化它，并尝试从另一个控制器调用loadVideoById？
