fn EventTarget~EventListener

The function to remove.

on(type, fn)

Adds an event listener to an instance of an EventTarget. An event listener is a function that will get called when an event with a certain name gets triggered.

Parameters:
Name Type Description
type string | Array.<string>

fn EventTarget~EventListener

The function to call with EventTargets
Inherited From:
Source:

one(type, fn)

This function will add an event listener that gets triggered only once. After the first trigger it will get removed. This is like adding an event listener with EventTarget#on that calls EventTarget#off on itself.

Parameters:
Name Type Description
type string | Array.<string>

An event name or an array of event names.
fn EventTarget~EventListener

The function to be called once for each event name.

removeEventListener()

An alias of EventTarget#off. Allows EventTarget to mimic the standard DOM API.

Inherited From:
Source:
event-target.js
See:

trigger(event)

This function causes an event to happen. This will then cause any event listeners that are waiting for that event, to get called. If there are no event listeners for an event then nothing will happen.

If the name of the Event that is being triggered is in EventTarget.allowedEvents_. Trigger will also call the on + uppercaseEventName function.

Example: 'click' is in EventTarget.allowedEvents_, so, trigger will attempt to call onClick if it exists.

Parameters:
Name Type Description
event string | EventTarget~Event | Object

The name of the event, an Event, or an object with a key of type set to an event name.

Source:

Events

selectedchange

An event that fires when selected changes on this track. This allows the VideoTrackList that holds this track to act accordingly.

Note: This is not part of the spec! Native tracks will do this internally without an event.
