How to allow only numeric (0-9) in HTML inputbox using jQuery?

Question

I am creating a web page where I have an input text field in which I want to allow only numeric characters like (0,1,2,3,4,5...9) 0-9.

How can I do this using jQuery

The cool thing is that it brings up a numeric keyboard on mobile devices, which is way better than using jQuery.
