函数f () {plr.requestFullscreen (); document.exitFullscreen ()};plr.requestFullscreen():document.exitFullscreen()}
<!DOCTYPE html><html><head>
<style>
body{background:#000}
#plr{position:relative;background:#fff;width:360px}
#vd{width:100%;background:grey}
button{width:48px;height:48px;border:0;background:grey}
</style>
</head><body>
<div id="plr">
<video id="vd" src="video.mp4"></video>
<button onclick="(plr.offsetWidth==360)?plr.requestFullscreen():document.exitFullscreen()">fs</button>
<button onclick="plr.requestFullscreen();document.exitFullscreen()">fs2</button>
</div>
</body></html>

这可能支持
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default5.aspx.cs" Inherits="PRODUCTION_Default5" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript">
function max()
{
window.open("", "_self", "fullscreen=yes, scrollbars=auto");
}
</script>
</head>
<body onload="max()">
<form id="form1" runat="server">
<div>
This is Test Page
</div>
</form>
</body>
</html>
这段代码还包括如何启用Internet Explorer 9的全屏，可能是更老的版本， 以及最新版本的谷歌Chrome。接受的答案也可以用于其他浏览器。
var el = document.documentElement
, rfs = // for newer Webkit and Firefox
el.requestFullscreen
|| el.webkitRequestFullScreen
|| el.mozRequestFullScreen
|| el.msRequestFullscreen
;
if(typeof rfs!="undefined" && rfs){
rfs.call(el);
} else if(typeof window.ActiveXObject!="undefined"){
// for Internet Explorer
var wscript = new ActiveXObject("WScript.Shell");
if (wscript!=null) {
wscript.SendKeys("{F11}");
}
}

Chrome全屏API(请注意，然而 requestFullscreen“只工作在”“[m]大多数UIEvents和鼠标事件，如点击和按下键等”，“所以它不能被恶意使用”) 如何使浏览器全屏使用F11键事件通过JavaScript
这个函数非常好用
function toggle_full_screen()
{
if ((document.fullScreenElement && document.fullScreenElement !== null) || (!document.mozFullScreen && !document.webkitIsFullScreen))
{
if (document.documentElement.requestFullScreen){
document.documentElement.requestFullScreen();
}
else if (document.documentElement.mozRequestFullScreen){ /* Firefox */
document.documentElement.mozRequestFullScreen();
}
else if (document.documentElement.webkitRequestFullScreen){ /* Chrome, Safari & Opera */
document.documentElement.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);
}
else if (document.msRequestFullscreen){ /* IE/Edge */
document.documentElement.msRequestFullscreen();
}
}
else
{
if (document.cancelFullScreen){
document.cancelFullScreen();
}
else if (document.mozCancelFullScreen){ /* Firefox */
document.mozCancelFullScreen();
}
else if (document.webkitCancelFullScreen){ /* Chrome, Safari and Opera */
document.webkitCancelFullScreen();
}
else if (document.msExitFullscreen){ /* IE/Edge */
document.msExitFullscreen();
}
}
}
要使用它，只需调用:
toggle_full_screen();
screenfull.js试试。这是一个很好的跨浏览器解决方案，应该也适用于Opera浏览器。
JavaScript全屏API跨浏览器使用的简单包装器，它允许您将页面或任何元素显示为全屏。消除了浏览器实现的差异，所以您不必这样做。
演示。
这里有一个完整的解决方案，以进入和退出全屏模式(即取消，退出，退出)
function cancelFullScreen() {
var el = document;
var requestMethod = el.cancelFullScreen||el.webkitCancelFullScreen||el.mozCancelFullScreen||el.exitFullscreen||el.webkitExitFullscreen;
if (requestMethod) { // cancel full screen.
requestMethod.call(el);
} else if (typeof window.ActiveXObject !== "undefined") { // Older IE.
var wscript = new ActiveXObject("WScript.Shell");
if (wscript !== null) {
wscript.SendKeys("{F11}");
}
}
}
function requestFullScreen(el) {
// Supports most browsers and their versions.
var requestMethod = el.requestFullScreen || el.webkitRequestFullScreen || el.mozRequestFullScreen || el.msRequestFullscreen;
if (requestMethod) { // Native full screen.
requestMethod.call(el);
} else if (typeof window.ActiveXObject !== "undefined") { // Older IE.
var wscript = new ActiveXObject("WScript.Shell");
if (wscript !== null) {
wscript.SendKeys("{F11}");
}
}
return false
}
function toggleFullScreen(el) {
if (!el) {
el = document.body; // Make the body go full screen.
}
var isInFullScreen = (document.fullScreenElement && document.fullScreenElement !== null) || (document.mozFullScreen || document.webkitIsFullScreen);
if (isInFullScreen) {
cancelFullScreen();
} else {
requestFullScreen(el);
}
return false;
}
