function fullScreen() {     var el = document.documentElement,         rfs = el.requestFullScreen || el.webkitRequestFullScreen || el.mozRequestFullScreen || el.msRequestFullScreen,         wscript;       if(typeof rfs != "undefined" && rfs) {         rfs.call(el);         return;     }       if(typeof window.ActiveXObject != "undefined") {         wscript = new ActiveXObject("WScript.Shell");         if(wscript) {             wscript.SendKeys("{F11}");         }     } }   function exitFullScreen() {     var el = document,         cfs = el.cancelFullScreen || el.webkitCancelFullScreen || el.mozCancelFullScreen || el.exitFullScreen,         wscript;       if (typeof cfs != "undefined" && cfs) {       cfs.call(el);       return;     }       if (typeof window.ActiveXObject != "undefined") {         wscript = new ActiveXObject("WScript.Shell");         if (wscript != null) {             wscript.SendKeys("{F11}");         }   } }
