A standalone javascript library for cross-browser mouse wheel support.

See it in action.

The event callback receives 3 extra arguments which are the normalized “deltas” of the mouse wheel.

var hamster = Hamster(el);

hamster.wheel(function(event, delta, deltaX, deltaY){
  console.log(delta, deltaX, deltaY);
});

// destroy
hamster.unwheel();

No jQuery or other libraries required, but an adapter for AngularJS is available.

Tested in these core browsers.

bower install hamsterjs
