The onchange
property of the MediaQueryList
interface is an event handler property representing a function that is invoked when the change
event fires, i.e when the status of media query support changes. The event object is a MediaQueryListEvent
instance, which is recognised as a MediaListQuery
instance in older browsers, for backwards compatibility purposes.
Syntax
MediaQueryList.onchange = function() { ... };
Example
var mql = window.matchMedia('(max-width: 600px)'); mql.addEventListener( "change", (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 than 600 pixels wide */ console.log('This is a wide screen — more than 600px wide.') } })
