TextTrack: addCue() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The addCue() method of the TextTrack interface adds a new cue to the list of cues.

Syntax

js
addCue(cue)

Parameters

cue

A TextTrackCue.

Note: The TextTrackCue interface is an abstract class used as the parent for other cue interfaces such as VTTCue. Therefore, when adding a cue you will be using one of the cue types that inherit from TextTrackCue.

Return value

Undefined.

Exceptions

InvalidStateError DOMException

Thrown if the rules for this TextTrackList do not match those that are appropriate for the incoming TextTrackCue.

Examples

In the following example two cues are added to a video text track using addCue().

js
let video = document.querySelector("video");
let track = video.addTextTrack("captions", "Captions", "en");
track.mode = "showing";
track.addCue(new VTTCue(0, 0.9, "Hildy!"));
track.addCue(new VTTCue(1, 1.4, "How are you?"));
