Sys.UI.DomEvent screenY Field
Gets the y-coordinate of the mouse pointer's position relative to the user's screen.
var screenY = domEventVar.screenY;
Return Value
An integer that represents the y-coordinate in pixels.
Remarks
Use the screenY field to get the vertical offset between the user's screen and the mouse pointer's position.
Example
The following example shows how to use the screenY field to retrieve the y-coordinate of the mouse pointer's position relative to the user's screen.
