Trigger 'dummy' mouse wheel event

Question

Is there a way to trigger a scroll wheel event with an arbitrary delta. Just like jQuery does with \'click\' like:

$(\'#selector\').trigger(\'click\');
         


        

Answer 1

I used this code in making my own scroll.

$('body').bind('mousewheel DOMMouseScroll', function(event) {
     var delta = Math.max(-1, Math.min(1, (event.originalEvent.wheelDelta || -event.originalEvent.detail))) * -1;
}

I added * -1 to invert. you can remove it.
