mobile-detect.js

A loose port of Mobile-Detect to JavaScript.

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)

Current master branch is using detection logic from [email protected]

Live Demo

@zeno created a very nice live-demo. See it in action with your device:

Demo

Usage

Browser

<script src="mobile-detect.js"></script>
<script>
    var md = new MobileDetect(window.navigator.userAgent);
    // ... see below
</script>

Node.js / Express

var MobileDetect = require('mobile-detect'),
    md = new MobileDetect(req.headers['user-agent']);
// ... see below

General

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:

Side Effects

Script creates the global property MobileDetect.

Modernizr Extension

When using Modernizr, you can include mobile-detect-modernizr.js. It will add the CSS classes mobile, phone, tablet and mobilegradea if applicable.

You can easily extend it, e.g. android, iphone, etc.

Alternatives / Infos

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
• Mobile-Detect A lightweight PHP class for detecting mobile devices (including tablets). This is the "source" of this JavaScript project and if you use PHP on your server you should use it!
• 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
• dmolsen/Detector Detector is a simple, PHP- and JavaScript-based browser- and feature-detection library that can adapt to new devices & browsers on its own without the need to pull from a central database of browser information.
• matthewhudson/device.js Conditional CSS and/or JavaScript based on device operating system, orientation and type
• 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.
• UAParser.js Lightweight JavaScript-based User-Agent String Parser
• MobileESP - Easily detect mobile web site visitors
• WURFL
• Handset and Tablet Detection
• Search on microjs.com

Mobile-Usage Statistics

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.

Contributing

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
• run npm install
• 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

Testing

Browser

Open tests/SpecRunner.html in different browsers.

Node.js

$ npm test
$ # or
$ grunt jasmine_node

Donations

If you want, you can donate to Mobile-Detect.

TODO

• Extend RegEx patterns so that test passes
