MediaQueryList: change event

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The change event of the MediaQueryList interface fires when the status of media query support changes.

Syntax

Use the event name in methods like addEventListener(), or set an event handler property.

js
addEventListener("change", (event) => {});

onchange = (event) => {};

Event type

Event properties

The MediaQueryListEvent interface inherits properties from its parent interface, Event.

MediaQueryListEvent.matches Read only

A boolean value that is true if the document currently matches the media query list, or false if not.

MediaQueryListEvent.media Read only

A string representing a serialized media query.

Example

js
const mql = window.matchMedia("(max-width: 600px)");

mql.onchange = (e) => {
  if (e.matches) {
    /* the viewport is 600 pixels wide or less */
    console.log("This is a narrow screen — less than 600px wide.");
  } else {
    /* the viewport is more than 600 pixels wide */
    console.log("This is a wide screen — more than 600px wide.");
  }
};
