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


<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>

注:实际应用中,可通过区分ie11 ie10,其它浏览器,控制按钮的显示、隐藏来实现 适用各浏览器的全屏功能;
