Removes an event listener for a specific event from an instance of EventTarget. This makes it so that the event listener will no longer get called when the named event happens.

Parameters:

• Overrides:

  • EventTarget#off

on(type, fn)

[event-target.js](https://docs.videojs.com/event-target.js.html), [line 58](https://docs.videojs.com/event-target.js.html#line58)

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:

• Overrides:

  • EventTarget#on

one(type, fn)

[event-target.js](https://docs.videojs.com/event-target.js.html), [line 112](https://docs.videojs.com/event-target.js.html#line112)

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:

• Overrides:

  • EventTarget#one

removeEventListener()

[event-target.js](https://docs.videojs.com/event-target.js.html), [line 99](https://docs.videojs.com/event-target.js.html#line99)

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

• Overrides:

  • EventTarget#removeEventListener

  See:

trigger(event)

[event-target.js](https://docs.videojs.com/event-target.js.html), [line 148](https://docs.videojs.com/event-target.js.html#line148)

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:

• Overrides:

  • EventTarget#trigger
