Скрипт определяет мобильное устройство или нет и выводит код

Есть к примеру код, который определяет мобильное устройстово:

/*! device.js 0.2.7 */

(function(){var a,b,c,d,e,f,g,h,i,j;b=window.device,a={},window.device=a,d=window.document.documentElement,j=window.navigator.userAgent.toLowerCase(),a.ios=function(){return a.iphone()||a.ipod()||a.ipad()},a.iphone=function(){return!a.windows()&&e("iphone")},a.ipod=function(){return e("ipod")},a.ipad=function(){return e("ipad")},a.android=function(){return!a.windows()&&e("android")},a.androidPhone=function(){return a.android()&&e("mobile")},a.androidTablet=function(){return a.android()&&!e("mobile")},a.blackberry=function(){return e("blackberry")||e("bb10")||e("rim")},a.blackberryPhone=function(){return a.blackberry()&&!e("tablet")},a.blackberryTablet=function(){return a.blackberry()&&e("tablet")},a.windows=function(){return e("windows")},a.windowsPhone=function(){return a.windows()&&e("phone")},a.windowsTablet=function(){return a.windows()&&e("touch")&&!a.windowsPhone()},a.fxos=function(){return(e("(mobile;")||e("(tablet;"))&&e("; rv:")},a.fxosPhone=function(){return a.fxos()&&e("mobile")},a.fxosTablet=function(){return a.fxos()&&e("tablet")},a.meego=function(){return e("meego")},a.cordova=function(){return window.cordova&&"file:"===location.protocol},a.nodeWebkit=function(){return"object"==typeof window.process},a.mobile=function(){return a.androidPhone()||a.iphone()||a.ipod()||a.windowsPhone()||a.blackberryPhone()||a.fxosPhone()||a.meego()},a.tablet=function(){return a.ipad()||a.androidTablet()||a.blackberryTablet()||a.windowsTablet()||a.fxosTablet()},a.desktop=function(){return!a.tablet()&&!a.mobile()},a.television=function(){var a;for(television=["googletv","viera","smarttv","internet.tv","netcast","nettv","appletv","boxee","kylo","roku","dlnadoc","roku","pov_tv","hbbtv","ce-html"],a=0;a<television.length;){if(e(television[a]))return!0;a++}return!1},a.portrait=function(){return window.innerHeight/window.innerWidth>1},a.landscape=function(){return window.innerHeight/window.innerWidth<1},a.noConflict=function(){return window.device=b,this},e=function(a){return-1!==j.indexOf(a)},g=function(a){var b;return b=new RegExp(a,"i"),d.className.match(b)},c=function(a){var b=null;g(a)||(b=d.className.replace(/^\s+|\s+$/g,""),d.className=b+" "+a)},i=function(a){g(a)&&(d.className=d.className.replace(" "+a,""))},a.ios()?a.ipad()?c("ios ipad tablet"):a.iphone()?c("ios iphone mobile"):a.ipod()&&c("ios ipod mobile"):a.android()?c(a.androidTablet()?"android tablet":"android mobile"):a.blackberry()?c(a.blackberryTablet()?"blackberry tablet":"blackberry mobile"):a.windows()?c(a.windowsTablet()?"windows tablet":a.windowsPhone()?"windows mobile":"desktop"):a.fxos()?c(a.fxosTablet()?"fxos tablet":"fxos mobile"):a.meego()?c("meego mobile"):a.nodeWebkit()?c("node-webkit"):a.television()?c("television"):a.desktop()&&c("desktop"),a.cordova()&&c("cordova"),f=function(){a.landscape()?(i("portrait"),c("landscape")):(i("landscape"),c("portrait"))},h=Object.prototype.hasOwnProperty.call(window,"onorientationchange")?"orientationchange":"resize",window.addEventListener?window.addEventListener(h,f,!1):window.attachEvent?window.attachEvent(h,f):window[h]=f,f(),"function"==typeof define&&"object"==typeof define.amd&&define.amd?define(function(){return a}):"undefined"!=typeof module&&module.exports?module.exports=a:window.device=a}).call(this);

Нужен скрипт, который будет выводить код в случае, если зашли с мобильного устройства - если с десктопа - то другой код.
