MediaList.mediaText

The mediaText property of the MediaList interface is a stringifier that returns a DOMString representing the MediaList as text, and also allows you to set a new MediaList.

Syntax

mediaListInstance.mediaText;
mediaListInstance.mediaText = string;

Value

A DOMString representing the media queries of a stylesheet. Each one is separated by a comma, for example screen and (min-width: 480px), print.

If you wish to set new media queries on the document, the string value must have the different queries separated by commas, e.g. screen, print. Note that the MediaList is a live list; updating the list via mediaText will immediately update the behavior of the document.

Also note that is you try to set mediaText to null, it will be treated as an empty string, i.e. the value will be set to "".

Examples

The following would log to the console a textual representation of the MediaList of the first stylesheet applied to the current document.

const stylesheets = document.styleSheets;
let stylesheet = stylesheets[0];
console.log(stylesheet.media.mediaText);
