event.screenY
Description
The screenY property of the Event object controls the vertical (y-coordinate) positioning within the computer screen in which the event occurred.
Example
Listing 7.212 shows an example of how to determine the y-coordinate of the cursor positioning relative to the computer screen when the click event occurs. The code captures the CLICK event. When captured, control is passed to the handle() function, which determines the y-coordinate position using the screenY property.
