代码如下
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<button onclick="fullScreen()">现代浏览器全屏</button>
<button onclick="exitScreen()">现代浏览器退出</button>
<button onclick="iefull()">低版本ie全屏</button>
</body>
<script type="text/javascript">
//全屏
function fullScreen() {
var el = document.documentElement;
var rfs = el.requestFullScreen || el.webkitRequestFullScreen || el.mozRequestFullScreen || el.msRequestFullscreen;
if (typeof rfs != "undefined" && rfs) {
rfs.call(el);
};
return;
}
//退出全屏
function exitScreen() {
if (document.exitFullscreen) {
document.exitFullscreen();
}
else if (document.mozCancelFullScreen) {
document.mozCancelFullScreen();
}
else if (document.webkitCancelFullScreen) {
document.webkitCancelFullScreen();
}
else if (document.msExitFullscreen) {
document.msExitFullscreen();
}
if (typeof cfs != "undefined" && cfs) {
cfs.call(el);
}
}
//ie低版本的全屏，退出全屏都这个方法
function iefull() {
var el = document.documentElement;
var rfs = el.msRequestFullScreen;
if (typeof window.ActiveXObject != "undefined") {
//这的方法 模拟f11键，使浏览器全屏
var wscript = new ActiveXObject("WScript.Shell");
if (wscript != null) {
wscript.SendKeys("{F11}");
}
}
}
//注：ie调用ActiveX控件，需要在ie浏览器安全设置里面把 ‘未标记为可安全执行脚本的ActiveX控件初始化并执行脚本’ 设置为启用
