track
Read only
The DOM track object the event is in reference to. If not null
, this is always an object of one of the media track types: AudioTrack
, VideoTrack
, or TextTrack
).
The removetrack
event is called whenever a track is removed from the media element whose audio tracks are represented by the AudioTrackList
object.
This event is not cancelable and does not bubble.
You can use this event to react to a new audio track becoming unavailable. You may want to update your UI elements to disallow for user selection of the removed audio track, for example.
Using addEventListener()
:
js
const videoElement = document.querySelector("video"); videoElement.audioTracks.addEventListener("removetrack", (event) => { console.log(`Audio track: ${event.track.label} removed`); });
Using the onremovetrack
event handler property:
js
const videoElement = document.querySelector("video"); videoElement.audioTracks.onremovetrack = (event) => { console.log(`Audio track: ${event.track.label} removed`); };
