mousewheel event is not triggering in firefox browser

Question

Please refer the below code.

$(this.element).on("mousewheel", this.chartMouseWheel);  chartMouseWheel:function(e) {         if(e.originalEvent.wheelDelta /120 > 0) {             alert('scrolling up !');         }         else{           alert('scrolling down !');         }          if (e.preventDefault)         e.preventDefault();         e.returnValue = false;     }, 

this event triggering properly in IE,chrome and not triggering in Firefox ?

Answer 1

This is 2017 and the right answer is now:

$(window).on('wheel', function(event){      // deltaY obviously records vertical scroll, deltaX and deltaZ exist too     if(event.originalEvent.deltaY < 0){         // wheeled up     }     else {         // wheeled down     } }); 

Works with current Firefox 51, Chrome 56, IE9+

Note: The value of the deltas will depend on the browser and the user settings.
