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