<!DOCTYPE html>

    </head>
    <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) {

              return;
        }
        //退出全屏
        function exitScreen(){
            if (document.exitFullscreen) {  
                document.exitFullscreen();

                //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
