The pageY read-only property of the MouseEvent interface returns the Y (vertical) coordinate in pixels of the event relative to the whole document. This property takes into account any vertical scrolling of the page. Originally, this property was defined as a long integer. The CSSOM View Module redefined it as a double float. See the Browser compatibility section for details.
