The cuechange
event fires when a TextTrack
has changed the currently displaying cues. The event is fired at both the TextTrack
and at the HTMLTrackElement
in which it's being presented, if any.

Examples
On the TextTrack
You can set up a listener for the cuechange
event on a TextTrack
using the addEventListener()
method:
track.addEventListener('cuechange', function () {
let cues = track.activeCues; // array of current cues
});
Or you can just set the oncuechange
event handler property:
track.oncuechange = function () {
let cues = track.activeCues; // array of current cues
}
On the track element
The underlying TextTrack
, indicated by the track
property, receives a cuechange
event every time the currently-presented cue is changed. This happens even if the track isn't associated with a media element.
If the track is associated with a media element, using the <track>
element as a child of the <audio>
or <video>
element, the cuechange
event is also sent to the HTMLTrackElement
.
let textTrackElem = document.getElementById("texttrack");
textTrackElem.addEventListener("cuechange", (event) => {
let cues = event.target.track.activeCues;
});
In addition, you can use the oncuechange
event handler:
let textTrackElem = document.getElementById("texttrack");
textTrackElem.oncuechange = (event) => {
let cues = event.target.track.activeCues;
});
