Using YouTube iframe API https://developers.google.com/youtube/iframe_api_reference
禁用全屏按钮：fs: 0
禁用键盘控制：禁用kb: 1
当播放器加载时，删除全屏选项：
// Get DOM video player not YT videoplayer
videoPlayer = document.getElementById('player');
// don't allow full screen
videoPlayer.allowFullscreen = false;
使用 Fullscreen_API 在 DOM 播放器（在我们的例子中是 iframe）上触发全屏
videoPlayer.requestFullScreen()
如果按下 ESC 键或视频结束，将发生全屏离开（自定义事件处理）
