In Javascript/jQuery, how can I detect if the client device has a mouse?
I've got a site that slides up a little info panel when the user hovers their mouse over an item. I'm using jQuery.hoverIntent to detect the hover, but this obviously doesn't work on touchscreen devices like iPhone/iPad/Android. So on those devices I'd like to revert to tap to show the info panel.
var isTouchDevice = 'ontouchstart' in document.documentElement;
Note: Just because a device supports touch events doesn't necessarily mean that it is exclusively a touch screen device. Many devices (such as my Asus Zenbook) support both click and touch events, even when they doen't have any actual touch input mechanisms. When designing for touch support, always include click event support and never assume any device is exclusively one or the other.
