addEventListener('cuechange', (event) => { })

oncuechange = (event) => { }

Event type

Examples

You can set up a listener for the cuechange event on a TextTrack using the addEventListener() method:

track.addEventListener('cuechange', () => {
  const cues = track.activeCues;  // array of current cues
  // …
});

Or you can set the oncuechange event handler property:

track.oncuechange = (event) => {
  let cues = track.activeCues; // array of current cues
}
