TextTrack.addCue()

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

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.
