如何获取同页面内另一个js内的匿名对象

Question

比如bilibili的window下的player对象，少了很多内置有用函数

window.player

1.  i {play: ƒ, pause: ƒ, reload: ƒ, seek: ƒ, volume: ƒ, …}

1.  addEventListener: ƒ (i,e)
2.  addViewPoints: ƒ (i)
3.  appendToPlaylist: ƒ (i)
4.  biliMessage: ƒ (i)
5.  destroy: ƒ (i)
6.  directiveDispatcher: ƒ (i)
7.  exitFullScreen: ƒ ()
8.  getBufferRate: ƒ ()
9.  getCurrentTime: ƒ ()
10.  getDuration: ƒ ()
11.  getHeight: ƒ ()
12.  getMediaInfo: ƒ ()
13.  getPlayerState: ƒ ()
14.  getPlaylist: ƒ ()
15.  getPlaylistIndex: ƒ ()
16.  getPlayurl: ƒ ()
17.  getSession: ƒ ()
18.  getState: ƒ ()
19.  getStatisticsInfo: ƒ ()
20.  getVersion: ƒ ()
21.  getVideoMessage: ƒ ()
22.  getWidth: ƒ ()
23.  isFullScreen: ƒ ()
24.  isMute: ƒ ()
25.  loadLab: ƒ (i,e)
26.  logger: ƒ (i)
27.  mock: ƒ (i)
28.  mode: ƒ (i)
29.  next: ƒ (i,e,t)
30.  noAuxiliary: ƒ ()
31.  ogvUpdate: ƒ (i,e)
32.  option: ƒ (i,e)
33.  pause: ƒ ()
34.  play: ƒ ()
35.  premiereToast: ƒ (i)
36.  prev: ƒ ()
37.  reload: ƒ (i)
38.  reloadAccess: ƒ (i)
39.  removeEventListener: ƒ (i,e)
40.  removeFromPlaylist: ƒ (i,e)
41.  screenshot: ƒ (i)
42.  seek: ƒ (i,e)
43.  setMaskFps: ƒ (i)
44.  setMute: ƒ ()
45.  setPlayerState: ƒ (i,e)
46.  setPlaylistIndex: ƒ (i,e)
47.  stop: ƒ ()
48.  switchSubtitle: ƒ (i)
49.  track: ƒ (i,e)
50.  updateGuideAttention: ƒ (i)
51.  updatePageList: ƒ ()
52.  updateSubtitle: ƒ (i)
53.  verticalDanmaku: ƒ (i)
54.  volume: ƒ (i)
55.  \_\_proto\_\_: Object

但是在私有的jsc-player.5b5d1dc6.js第28098行下断点拦截到的player对象

this.player

那么如何导出这个this对象使其可以在外部js里调用呢？
