This script will detect the device by comparing patterns against a given User-Agent string. You can find out information about the device rendering your web page:
- mobile or not
- if mobile, whether phone or tablet
- operating system
- Mobile Grade (A, B, C)
- specific versions (e.g. WebKit)
master branch is using detection logic from Mobile-Detect@2.8.5
<script src="mobile-detect.js"></script> <script> var md = new MobileDetect(window.navigator.userAgent); // ... see below </script>
var MobileDetect = require('mobile-detect'), md = new MobileDetect(req.headers['user-agent']); // ... see below
var md = new MobileDetect( 'Mozilla/5.0 (Linux; U; Android 4.0.3; en-in; SonyEricssonMT11i' + ' Build/4.1.A.0.562) AppleWebKit/534.30 (KHTML, like Gecko)' + ' Version/4.0 Mobile Safari/534.30'); // more typically we would instantiate with 'window.navigator.userAgent' // as user-agent; this string literal is only for better understanding console.log( md.mobile() ); // 'Sony' console.log( md.phone() ); // 'Sony' console.log( md.tablet() ); // null console.log( md.userAgent() ); // 'Safari' console.log( md.os() ); // 'AndroidOS' console.log( md.is('iPhone') ); // false console.log( md.is('bot') ); // false console.log( md.version('Webkit') ); // 534.3 console.log( md.versionStr('Build') ); // '4.1.A.0.562' console.log( md.match('playstation|xbox') ); // false
There is some documentation generated by JSDoc:

When using Modernizr, you can include
It will add the CSS classes
mobilegradea if applicable.

Often device detection is the first solution in your mind. Please consider looking for other solutions like media queries and feature detection (e.g. w/ Modernizr). Maybe there are better (simpler, smaller, faster) device detection libraries, so here you have a list (order has no meaning apart from first element):
- Modernizr In most cases the better solution: don't use knowledge about device and version, but detect features (touch, canvas, ...)
- Mozilla Hacks - User-Agent detection, history and checklist
- Detect Mobile Browsers Open source mobile phone detection in many languages and for Webservers (Apache, nginx, IIS). mobile-detect.js uses the code of this library as a fallback in case of incomplete detection regular expressions.
- sebarmeli / JS-Redirection-Mobile-Site JS to handle the redirection to the mobile version of your site
- brendanlim/mobile-fu Automatically detect mobile requests from mobile devices in your Rails application.
- FormFactor FormFactor helps you customize your web app for different form factors, e.g. when you make "the mobile version", "the TV version", etc.
- MobileESP - Easily detect mobile web site visitors
- Handset and Tablet Detection
- Search on microjs.com
If you have to provide statistics about how many and which mobile devices are hitting your web-site, you can generate statistics (data and views) with hgoebl/mobile-usage. There are many hooks to customize statistical calculation to your needs.

Your contribution is welcome. If you want new devices to be supported, please contribute to Mobile-Detect instead.
To run generate-script it is necessary to have Mobile-Detect
as a sibling directory to mobile-detect.js/.
(I tried to use
git subtree but had some problems on Mac OS X - probably my fault...)
- fork or clone serbanghita/Mobile-Detect
- fork hgoebl/mobile-detect.js
- create branch
- make changes and run
grunt(needs PHP >= 5.4 in your path)
- run browser test (tests/SpecRunner.html)
- commit, push to your branch
- create pull request
tests/SpecRunner.html in different browsers.
$ npm test $ # or $ grunt jasmine_node
