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>

在较新的浏览器中，如Chrome 15, Firefox 10, Safari 5.1, IE 10，这是可能的。根据浏览器设置，旧版本的IE也可以通过ActiveX实现。
以下是如何做到这一点:
function requestFullScreen(element) {
// Supports most browsers and their versions.
var requestMethod = element.requestFullScreen || element.webkitRequestFullScreen || element.mozRequestFullScreen || element.msRequestFullScreen;
if (requestMethod) { // Native full screen.
requestMethod.call(element);
} else if (typeof window.ActiveXObject !== "undefined") { // Older IE.
var wscript = new ActiveXObject("WScript.Shell");
if (wscript !== null) {
wscript.SendKeys("{F11}");
}
}
}
var elem = document.body; // Make the body go full screen.
requestFullScreen(elem);
用户显然需要首先接受全屏请求，并且不可能在页面加载时自动触发此请求，它需要由用户触发(例如。一个按钮)

简单的例子:http://www.longtailvideo.com/blog/26517/using-the-browsers-new-html5-fullscreen-capabilities/
<script type="text/javascript">
function goFullscreen(id) {
// Get the element that we want to take into fullscreen mode
var element = document.getElementById(id);
// These function will not exist in the browsers that don't support fullscreen mode yet,
// so we'll have to check to see if they're available before calling them.
if (element.mozRequestFullScreen) {
// This is how to go into fullscren mode in Firefox
// Note the "moz" prefix, which is short for Mozilla.
element.mozRequestFullScreen();
} else if (element.webkitRequestFullScreen) {
// This is how to go into fullscreen mode in Chrome and Safari
// Both of those browsers are based on the Webkit project, hence the same prefix.
element.webkitRequestFullScreen();
}
// Hooray, now we're in fullscreen mode!
}
</script>
<img class="video_player" src="image.jpg" id="player"></img>
<button onclick="goFullscreen('player'); return false">Click Me To Go Fullscreen! (For real)</button>
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。

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}");
}
}
