The id
property contains a string which uniquely identifies the track represented by the AudioTrack
. This ID can be used with the AudioTrackList.getTrackById()
method to locate a specific track within the media associated with a media element.
The track ID can also be used as the fragment of a URL that loads the specific track (if the media supports media fragments).
Syntax
var trackID = AudioTrack.id;
Value
A DOMString
which identifies the track, suitable for use when calling getTrackById()
on an AudioTrackList
such as the one specified by a media element's audioTracks
property.
