推荐答案
INVALID_STATE_ERR：DOM例外11 webkitEnterFullscreen 时，可能会发生$ c>。最简单的解决方案是通过将其放入分配给视频的 loadedmetadata 事件的回调函数来推迟调用 webkitEnterFullscreen 。
INVALID_STATE_ERR: DOM Exception 11 can occur when a call to webkitEnterFullscreen is made before the video element has received its asset's metadata. The simplest solution is to defer the invocation of webkitEnterFullscreen by putting it in a callback function assigned to the video's loadedmetadata event.
在移动环境中，您需要通过将该调用附加到可触摸元素来更进一步，以便用户启动它，因为必须驱动播放和全屏操作通过移动环境中的用户交互。
In a mobile environment, you need to take things a step further by attaching that call to a touchable element so that it is user initiated since play and fullscreen actions must be driven by user interaction in mobile environments.
代码看起来应该是这样的：
The code should look kind of like this:
var video, play, fullscreen;
video = document.createElement('video');
video.src = 'my_cool_video.mp4';
video.addEventListener('loadedmetadata', function () {
fullscreen.disabled = false;
}, false);
play = document.createElement('button');
play.innerHTML = 'PLAY';
play.addEventListener('click', function () {
video.play();
}, false);
fullscreen = document.createElement('button');
fullscreen.innerHTML = 'FULLSCREEN';
fullscreen.disabled = true;
fullscreen.addEventListener('click', function () {
video.webkitEnterFullscreen();
}, false);
document.body.appendChild(video);
document.body.appendChild(play);
documnet.body.appendChild(fullscreen);
