The screenY read-only property of the MouseEvent interface provides the vertical coordinate (offset) of the mouse pointer in global (screen) coordinates.

Syntax

var pixelNumber = instanceOfMouseEvent.screenY

Return value

double floating point value. Early versions of the spec defined this as an interger referring to the number of pixels. See the Browser compatibility section for details.

Example

<html>
<head>
<title>screenX\screenY example</title>

<script type="text/javascript">

function showCoords(evt){
  alert(
    "screenX value: " + evt.screenX + "\n"
    + "screenY value: " + evt.screenY + "\n"
  );
}

</script>
</head>

<body onmousedown="showCoords(event)">
<p>To display the mouse coordinates click anywhere on the page.</p>
</body>
</html>
