如何使用JavaScript使访问者的浏览器全屏显示，同时兼容IE、Firefox和Opera?
当前回答
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)

既然全屏api越来越广泛，而且似乎越来越成熟，为什么不试试Screenfull.js呢?我昨天第一次使用它，今天我们的应用程序在(几乎)所有浏览器中真正全屏!
确保它与CSS中的:fullscreen伪类相结合。详见https://www.sitepoint.com/use-html5-full-screen-api/。

我用过这个…
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<script language="JavaScript">
function fullScreen(theURL) {
window.open(theURL, '', 'fullscreen=yes, scrollbars=auto');
}
// End -->
</script>
</head>
<body>
<h1 style="text-align: center;">
Open In Full Screen
</h1>
<div style="text-align: center;"><br>
<a href="javascript:void(0);" onclick="fullScreen('http://google.com');">
Open Full Screen Window
</a>
</div>
</body>
</html>
以下是我对全屏和退出全屏的完整解决方案(非常感谢上面塔的回答):
$(document).ready(function(){
$.is_fs = false;
$.requestFullScreen = function(calr)
{
var element = document.body;
// 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}");
}
}
$.is_fs = true;
$(calr).val('Exit Full Screen');
}
$.cancel_fs = function(calr)
{
var element = document; //and NOT document.body!!
var requestMethod = element.exitFullScreen || element.mozCancelFullScreen || element.webkitExitFullScreen || element.mozExitFullScreen || element.msExitFullScreen || element.webkitCancelFullScreen;
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}");
}
}
$(calr).val('Full Screen');
$.is_fs = false;
}
$.toggleFS = function(calr)
{
$.is_fs == true? $.cancel_fs(calr):$.requestFullScreen(calr);
}
});
// 调用:
<input type="button" value="Full Screen" onclick="$.toggleFS(this);" />
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。
