javascript - Activating a jquery function only in desktop mode? -


i have jquery funciton sticks navbar top of webpage, want feature in desktop , tablet mode (not in phone mode). how de-activate function?

$(document).scroll(function(){     var elem = $('.navbar');     if (!elem.attr('data-top')) {         if (elem.hasclass('navbar-fixed-top'))             return;         var offset = elem.offset()         elem.attr('data-top', offset.top);     }     if (elem.attr('data-top')  <= $(this).scrolltop() )         elem.addclass('navbar-fixed-top');     else         elem.removeclass('navbar-fixed-top');  });

use css media queries manipulate nav bar. browser/os detection shouldn't factor styling, resolution , media type.

what syntax css media query applies more 1 property (and operator)?
