Sets or retrieves the y-coordinate (in pixels) of the mouse pointer, or user's finger, offset from the closest relatively positioned parent element of the element that fired the event.

Property values
Type: Integer
the y-coordinate, in pixels.
Remarks
The property is read-only in Microsoft Internet Explorer 4.0, and read/write in Microsoft Internet Explorer 5 and later. In browser versions earlier than Internet Explorer 5, the y property retrieves a coordinate relative to the client.
If the event firing element is relatively positioned, then the y-coordinate from the boundary of the element is returned. If the event firing element and all of its parent elements are not relatively positioned, then the y property returns a coordinate relative to the body element.
The y property returns a coordinate relative to the body element.
If the mouse or finger is outside the window at the time the event fires, this property returns -1.
Examples
This example displays the current mouse position in the browser's status window.
<BODY onmousemove="window.status = 'X=' + window.event.x +
' Y=' + window.event.y">
