MediaList: item() method

The item() method of the MediaList interface returns the media query at the specified index, or null if the specified index doesn't exist.

Syntax

js
item(index)
[index]

Note: The bracket ([]) syntax can be used instead of the item() syntax.

Parameters

index

An integer.

Return value

If the bracket ([]) syntax is used and there is no entry for the given index, undefined is returned.

Examples

The following would log to the console each media query stored in the MediaList associated with the first stylesheet applied to the current document.

js
const stylesheet = document.styleSheets[0];
console.log(stylesheet.media.length);
console.log(stylesheet.media.item(0)); // Returns a string like "print"
console.log(stylesheet.media.item(5)); // Returns null if there is no 5th entry
console.log(stylesheet.media[1]); // Returns a string like "print"
console.log(stylesheet.media[5]); // Returns undefined if there is no 5th entry
