jQuery Waypoints throws Uncaught Error: No handler option passed to Waypoint constructor -

i using waypoint version 3.1.1 jquery version using sticky shortcut call code

$('.navwrap').waypoint('sticky', {   direction: 'up', });

but "uncaught error: no handler option passed waypoint constructor" , waypoint not fire.

what doing wrong?

as error suggests, waypoints requires "handler" option, defines callback function when scroll waypoint element:

$('.navwrap').waypoint('sticky', {     direction: 'up',     handler: function(direction) {         alert(direction);     } });

you try doing using new no-framework paradigm:

var sticky = new waypoint.sticky({   element: $('.navwrap')[0] });
