TextTrack: language property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The language read-only property of the TextTrack interface returns the language of the text track.

This uses the same values as the HTML lang attribute. These values are documented in RFC 5646: Tags for Identifying Languages (also known as BCP 47).

Value

A string containing a language identifier. For example, "en-US" for United States English or "pt-BR" for Brazilian Portuguese.

Examples

In the following example the value of language is printed to the console.

js
let video = document.querySelector("video");
let track = video.addTextTrack("captions", "Captions", "en-US");
track.mode = "showing";
console.log(track.language);
