Sys.UI.DomEvent screenY Field

Gets the y-coordinate of the mouse pointer's position relative to the user's screen.

Syntax

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.

cs

<script type="text/javascript">
    Sys.UI.DomEvent.addHandler($get("Button1"), "click", processEventInfo);

    function processEventInfo(eventElement) {
        var result = '';
        try {
            result += "altKey = " + eventElement.altKey + "<br/>";
            result += "button = " + eventElement.button + "<br/>";
