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

Syntax

var y = instanceOfMouseEvent.screenY

Return value

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

Example

This example displays your mouse's coordinates whenever you trigger the mousemove event.

HTML

<p>Move your mouse to see its position.</p>
<p id="screen-log"></p>

JavaScript

let screenLog = document.querySelector('#screen-log');
document.addEventListener('mousemove', logKey);

function logKey(e) {
  screenLog.innerText = `
    Screen X/Y: ${e.screenX}, ${e.screenY}
    Client X/Y: ${e.clientX}, ${e.clientY}`;
}
