MediaList: toString() method
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2015.
The toString()
stringifier method of the MediaList
interface returns a string representing the object's values. The value is a comma-separated list of media values in the same format as the MediaList.mediaText
property.
Syntax
js
toString()
Parameters
None.
Return value
A string.
Examples
js
const firstStyleSheet = document.styleSheets[0]; // the document's first stylesheet
const mediaList = firstStyleSheet.media; // the mediaList of the stylesheet
// set the `media` text to a media query value
mediaList.mediaText = "SCREEN AND (140PX <= WIDTH <= 380PX)";
// add a second media value
mediaList.appendMedium(
"SCREEN AND (MAX-HEIGHT: 400PX) AND (ORIENTATION: LANDSCAPE))",
);
// erroneously, add the same media query again
mediaList.appendMedium(
"SCREEN AND (MAX-HEIGHT: 400PX) AND (ORIENTATION: LANDSCAPE))",
);
console.log(mediaList.toString());
// "screen and (140px <= width <= 380px), screen and (max-height: 400px) and (orientation: landscape)"
