Detecting Mobile Devices with JavaScript

for simpler applications, the following snippet can be useful

var isMobile = {
Android: function() {
return navigator.userAgent.match(/Android/i);
},
BlackBerry: function() {
return navigator.userAgent.match(/BlackBerry/i);
},
iOS: function() {
return navigator.userAgent.match(/iPhone|iPad|iPod/i);
},
Opera: function() {
return navigator.userAgent.match(/Opera Mini/i);
},
Windows: function() {
return navigator.userAgent.match(/IEMobile/i);
},
any: function() {
return (isMobile.Android() || isMobile.BlackBerry() || isMobile.iOS() || isMobile.Opera() || isMobile.Windows());
}
};

Examples

To check to see if the user is on any of the supported mobile devices:

if( isMobile.any() ) alert(‘Mobile’);

To check to see if the user is on a specific mobile device:

if( isMobile.iOS() ) alert(‘iOS’);
