- deltaY
- Gets the distance that a mouse wheel has rotated around the y-axis (vertical).
- deltaZ

No events.
Inherited from MouseEvent
Properties
- button
- Gets the mouse button that caused an event.
- buttons
- Gets a value that indicates which mouse buttons a user pressed.
- clientX
- Gets the x-coordinate of the mouse pointer, relative to the upper-left corner of the viewport (that is, the user agent’s client area).
- clientY
- Gets the y-coordinate of the mouse pointer, relative to the upper-left corner of the viewport (that is, the user agent’s client area).
- layerX
- Gets the x-coordinate of the mouse pointer, relative to the last positioned ancestor element.
- layerY
- Returns the horizontal coordinate of the event relative to the current layer. layerY is a non-standards property of the MouseEvent object.
- relatedTarget
- Gets the secondary element that is involved in an event. The relatedTarget property is used to find the other element, if any, involved in an event. Events like mouseover are oriented around a certain target, but also involve a secondary target, such as the target that is exited as the mouseover event fires for the primary target.
- screenX
- Gets the x-coordinate of the mouse pointer, relative to the upper-left corner of the screen.
- screenY
- Gets the y-coordinate of the mouse pointer, relative to the upper-left corner of the screen.
- x
- Gets the x-coordinate of the mouse cursor, relative to the last positioned ancestor element.
- y
- Gets the y-coordinate of the mouse pointer, relative to the last positioned ancestor element.
