GlobalEventHandlers.onmouseout

The onmouseout property of the GlobalEventHandlers mixin is an event handler that processes mouseout events.

The mouseout event fires when the mouse leaves an element. For example, when the mouse moves off of an image in the web page, the mouseout event is raised for that image element.

Syntax

element.onmouseout = function;

Example

This example adds an onmouseout and an onmouseover event to a paragraph. Try moving your mouse over and out of the element.

HTML

<p>Test your mouse on me!</p>

JavaScript

const p = document.querySelector('p');
p.onmouseover = logMouseOver;
p.onmouseout = logMouseOut;

function logMouseOver() {
  p.textContent = 'MOUSE OVER detected';
}

function logMouseOut() {
  p.textContent = 'MOUSE OUT detected';
}
