What's the best way to detect a 'touch screen' device using JavaScript?

Question

I\'ve written a jQuery plug-in that\'s for use on both desktop and mobile devices. I wondered if there is a way with JavaScript to detect if the device has touch screen capa

Answer 1

I would avoid using screen width to determine if a device is a touch device. There are touch screens much larger than 699px, think of Windows 8. Navigatior.userAgent may be nice to override false postives.

I would recommend checking out this issue on Modernizr.

Are you wanting to test if the device supports touch events or is a touch device. Unfortunately, that's not the same thing.
