API

require('mouse-wheel')(element, callback, noScroll)

Hook an event handler for the mouse wheel on element.

• element is an optional DOM element, or if unspecified then is the window object.
• callback(dx, dy, dz, ev) is called whenever the mouse scrolls
  • dx, dy, dz is the amount of scrolling vertically, horizontally and depth-wise in pixels
  • ev is the MouseEvent object associated with the event
• noScroll is an optional flag, which if set disables scrolling the page

Returns listener function listener so that it may be detached later with element.removeEventListener('wheel', listener)
