js 实现各浏览器全屏

现代浏览器包括ie11，可以直接用h5的全屏api实现
低版本的IE需要通过ActiveX插件实现；

//直接上代码

<!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 src="js/jquery-2.1.1.js" type="text/javascript" charset="utf-8"></script>
    <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 </script>
