The read-only AudioTrack
property label
returns a string specifying the audio track's human-readable label, if one is available; otherwise, it returns an empty string.
A string specifying the track's human-readable label, if one is available in the track metadata. Otherwise, an empty string (""
) is returned.
For example, a track whose kind
is "commentary"
might have a label
such as "Commentary with director Mark Markmarkimark and star Donna Donnalidon"
.
This example returns an array of track kinds and labels for potential use in a user interface to select audio tracks for a specified media element. The list is filtered to only allow certain track kinds through.
js
function getTrackList(el) { const trackList = []; const wantedKinds = [ "main", "alternative", "main-desc", "translation", "commentary", ]; el.audioTracks.forEach((track) => { if (wantedKinds.includes(track.kind)) { trackList.push({ id: track.id, kind: track.kind, label: track.label, }); } }); return trackList; }
The resulting trackList
contains an array of audio tracks whose kind
is one of those in the array wantedKinds
, with each entry providing the track's id
, kind
, and label
.
