How do I check Windows Phone useragent with javascript?

Question

I can check for iPhone with this code:

(navigator.userAgent.match(/iPhone/i))

But I want to target Windows Phone with this userAgent:

Answer 1

Nokia Lumia or any WPhone browser has desktop and mobile browsing mode, IEMobile sends different user agent. Desktop mode does not send Windows Phone X.Y model argument. Find Windows+ARM+Touch+WPDesktop tags and possibly screen size to guess wphone or tablet. Its a hack I know.
