MediaQueryList.media - Web APIs 编辑

The media read-only property of the MediaQueryList interface is a DOMString representing a serialized media query.

Syntax

var media = MediaQueryList.media;

Value

A DOMString representing a serialized media query.

Examples

This example runs the media query (max-width: 600px) and displays the value of the resulting MediaQueryList's media property in a <span>.

JavaScript

let mql = window.matchMedia('(max-width: 600px)');

document.querySelector(".mq-value").innerText = mql.media;

The JavaScript code passes the media query to match into matchMedia() to compile it, then sets the <span>'s innerText to the value of the result's media property.

HTML

<span class="mq-value"></span>

A simple <span> to receive the output.

CSS

.mq-value {
  font: 18px arial, sans-serif;
  font-weight: bold;
  color: #88f;
  padding: 0.4em;
  border: 1px solid #dde;
}
