javascript - YouTube Player API 检测全屏退出

Question

所以基本上有一个按钮，点击它会打开并全屏播放视频。我想在用户退出全屏但无法捕获该事件时停止视频。

现在我用它作为开始 http://codepen.io/bfred-it/pen/GgOvLM

谁能告诉我一个可能的解决方案。

HTML:

<script src="https://www.youtube.com/iframe_api"></script>
<button>play fullscreen</button><br>
<div id="player"></div>

JS:

var player, iframe;
var $ = document.querySelector.bind(document);

// init player
function onYouTubeIframeAPIReady() {
  player = new YT.Player('player', {
    height: '200',
    width: '300',
    videoId: 'dQw4w9WgXcQ',
    events: {
      'onReady': onPlayerReady
    }
  });
}

// when ready, wait for clicks
function onPlayerReady(event) {
  var player = event.target;
  iframe = $('#player');
  setupListener(); 
}

function setupListener (){
$('button').addEventListener('click', playFullscreen);
}

function playFullscreen (){
  player.playVideo();//won't work on mobile

  var requestFullScreen = iframe.requestFullScreen || iframe.mozRequestFullScreen || iframe.webkitRequestFullScreen;
  if (requestFullScreen) {
    requestFullScreen.bind(iframe)();
  }
}

您可以检测浏览器何时full screen change然后停止视频

document.addEventListener("fullscreenchange", function() {
  if (!document.fullscreenElement) player.stopVideo();
}, false);

document.addEventListener("msfullscreenchange", function() {
  if (!document.msFullscreenElement) player.stopVideo();
}, false);

document.addEventListener("mozfullscreenchange", function() {
  if (!document.mozFullScreen) player.stopVideo();
}, false);

document.addEventListener("webkitfullscreenchange", function() {
  if (!document.webkitIsFullScreen) player.stopVideo();
}, false);
