You can define a user agent in the global object navigator.userAgent and you can already recognize it by the agent and recognize the device.
if (/Android|webOS|iPhone|iPad|iPod|BlackBerry|BB|PlayBook|IEMobile|Windows Phone|Kindle|Silk|Opera Mini/i.test(navigator.userAgent)) { // ΠΠΎΠ»ΡΠ·ΠΎΠ²Π°ΡΠ΅Π»Ρ ΡΠΈΠ΄ΠΈΡ Ρ ΠΌΠΎΠ±ΠΈΠ»ΡΠ½ΠΎΠ³ΠΎ ΠΏΡΠΈΠ»ΠΎΠΆΠ΅Π½ΠΈΡ ΠΈΠ»ΠΈ ΡΠ°Π±Π»Π΅ΡΠΊΠΈ } Jurij Jazdanov Jurij Jazdanov
