在现代浏览器中以全屏模式显示时，如何显示自定义视频控件?
How can I display custom video controls when the in fullscreen mode in modern browsers?
一旦我全屏显示，它们就会消失.我希望它们可以使用，然后编写一些JavaScript以在不活动时将其隐藏，并在有人摇动鼠标时将其显示.
They disappear as soon as I go fullscreen. I'd like them to be available, and then I'll write some JavaScript to hide them on inactivity and show them once someone wiggles their mouse around.
HTML:
<video#video src="vid.mp4" preload poster="/images/poster.jpg">
<iframe src="https://youtube.com/embed/id" frameborder="0" allowfullscreen>
</video>
JS:
var bigPlayButton = document.getElementById('big-play-button')
var video = document.getElementById('video')
var playPauseButton = document.getElementById('play-pause')
var fullscreen = document.getElementById('fullscreen')
function toggleFullScreen() {
if (!document.fullscreenElement) {
document.documentElement.requestFullscreen()
} else {
if (document.exitFullscreen) {
document.exitFullscreen()
}
}
}
fullscreen.addEventListener('click', function (event) {
if (!video.classList.contains('fullscreen')) {
video.requestFullscreen()
} else {
document.exitFullscreen()
}
}, false)
// Detect FullScreen changes and adjust button
document.addEventListener('fullscreenchange', function (event) {
if (document.fullscreenElement) {
fullscreen.children[0].src = '/images/nofullscreen.svg'
video.classList.add('fullscreen')
} else {
fullscreen.children[0].src = '/images/fullscreen.svg'
video.classList.remove('fullscreen')
}
}, false)
CSS
video::-webkit-media-controls {
display: none !important;
}
#custom-video-controls {
z-index: 2147483648;
}

重大变化是针对父标记:.vidFrame用于全屏显示，而不是按照Kaido的评论显示的<video>标记.
Edit
The significant change was targeting the parent tag: .vidFrame for fullscreen instead of the <video> tag as per Kaido's comment.
如果要覆盖HTML5视频控件，则需要进行特殊处理.我假设您要这样做，因为控件已经具有内置于控件中的全屏功能.该演示实现:
HTML5 video's controls need special handling if you want to override them. I'm assuming you want to do that since the controls already have the full screen feature built in the controls. This demo implements:
-
classList用于切换.on和.off的button#fullScreen状态以及.play和.pause的button#playPause状态. -
:fullscreen伪类，以确保在全屏模式下，.vidBar位于底部. -
Shadow DOM覆盖本机播放器控件所需的CSS样式. -
Fullscreen API特定于供应商的进入和退出全屏模式的方法. - 没有音量滑块，静音按钮或洗涤器，只有全屏按钮(
button#fullScreen)和播放按钮(button#playPause).如果您需要它们，请问另一个问题. - 详细信息在源中带有注释.
classListfor toggling thebutton#fullScreenstates of.onand.offandbutton#playPausestates of.playand.pause.:fullscreenpseudo-class to insure.vidBaris on the bottom when in full screen mode.Shadow DOMCSS Styles that are needed to override the native player's controls.Fullscreen APIvendor specific methods to enter and exit full screen mode of course.- There's no volume slider, mute button, or scrubber, just the full screen button (
button#fullScreen) and play button (button#playPause). If you want them, ask another question. - Details are commented in source.
该代码段似乎未完全正常运行，因此这是一个正常运行的 柱塞 .如果无法达到该版本，请查看 嵌入式柱塞 ，然后单击全屏按钮:
It looks as if the Snippet isn't fully functional, so here's a functional Plunker. If that version cannot be reached, then review the embedded Plunker and click the full view button:
