Example Usage
I include the minified version of the script, inline, and at the top of the <head>. Cellular connections tend to suck, so it would be wasteful overhead to open another connection, just to download <1kb of JS:
1 <!DOCTYPE html> 2 <html lang="en"> 3 <head> 4 <meta charset="utf-8"> 5 <script> 6 // Minified version of isMobile included in the HTML since it's <1kb 7 (function(i){var e=/iPhone/i,n=/iPod/i,o=/iPad/i,t=/(?=.*Android)(?=.*Mobile)/i,r=/Android/i,d=/BlackBerry/i,s=/Opera Mini/i,a=/IEMobile/i,b=/(?=.*Firefox)(?=.*Mobile)/i,h=RegExp("(?:Nexus 7|BNTV250|Kindle Fire|Silk|GT-P1000)","i"),c=function(i,e){return i.test(e)},l=function(i){var l=i||navigator.userAgent;this.apple={phone:c(e,l),ipod:c(n,l),tablet:c(o,l),device:c(e,l)||c(n,l)||c(o,l)},this.android={phone:c(t,l),tablet:!c(t,l)&&c(r,l),device:c(t,l)||c(r,l)},this.other={blackberry:c(d,l),opera:c(s,l),windows:c(a,l),firefox:c(b,l),device:c(d,l)||c(s,l)||c(a,l)||c(b,l)},this.seven_inch=c(h,l),this.any=this.apple.device||this.android.device||this.other.device||this.seven_inch},v=i.isMobile=new l;v.Class=l})(window); 8 9 10 // My own arbitrary use of isMobile, as an example 11 (function () { 12 var MOBILE_SITE = '/mobile/index.html', // site to redirect to 13 NO_REDIRECT = 'noredirect'; // cookie to prevent redirect 14 15 // I only want to redirect iPhones, Android phones and a handful of 7" devices 16 if (isMobile.apple.phone || isMobile.android.phone || isMobile.seven_inch) { 17 18 // Only redirect if the user didn't previously choose 19 // to explicitly view the full site. This is validated 20 // by checking if a "noredirect" cookie exists 21 if ( document.cookie.indexOf(NO_REDIRECT) === -1 ) { 22 document.location = MOBILE_SITE; 23 } 24 } 25 })(); 26 </script> 27 </head> 28 <body> 29 <!-- imagine lots of html and content --> 30 </body> 31 </html>
