TextTrackList extension type

The TextTrackList interface is used to represent a list of the text tracks defined by the track element, with each track represented by a separate textTrack object in the list.

Retrieve an instance of this object with the HTMLMediaElement.textTracks property of an HTMLMediaElement object.

For a given HTMLMediaElement object media, the individual tracks can be accessed using:

  • media.TextTracks[n], to get the n-th text track from the object's list of text tracks

  • the media.textTracks.getTrackById() method

Methods

addEventListener(String type, EventListener? callback, [JSAny options]) → void
The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.
inherited
dispatchEvent(Event event) → bool
The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) also apply to events dispatched manually with dispatchEvent().
inherited
getTrackById(String id) → TextTrack?
The TextTrackList method getTrackById() returns the first TextTrack object from the track list whose id matches the specified string. This lets you find a specified track if you know its ID string.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
removeEventListener(String type, EventListener? callback, [JSAny options]) → void
The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
