J1 Integration

The detection library platform.js is integrated in the Javascript core library of J1 Template and exports all available methods (like platform.name) to the document scope (window).

Chrome Browser (August 2022) on Windows 10 64 bit edition
var platform_name         = platform.name;          // Chrome
var platform_version      = platform.version;       // 104.0.0.0
var platform_layout       = platform.layout;        // Blink
var platform_os           = platform.os;            // Windows 10 64 bit
var platform_description  = platform.description;   // Chrome 104.0.0.0 on Windows 10 64 bit
Safari Browser on iPad
var platform_name         = platform.name;            // Safari

var platform_product      = platform.product;         // iPad
var platform_manufacturer = platform.manufacturer;    // Apple

var platform_description  = platform.description;     // Safari 5.1 on Apple iPad (iOS 5.0)
Parsing a given UA string
var info = platform.parse('
  Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7.2; en; rv:2.0)
   Gecko/20100101 Firefox/4.0 Opera 11.52
');
var info_name             = info.name;                // Opera
var info_version          = info.version;             // 11.52
var info_layout           = info.layout;              // Presto
var info_os               = info.os;                  // Mac OS X 10.7.2
