Overrides:
See:

dispatchEvent()
event-target.js, line 175

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

Overrides:
See:

off(type, fn)
event-target.js, line 88

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

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

The function to remove.
Overrides:

on(type, fn)
event-target.js, line 58

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>

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

The function to call with EventTargets
Overrides:

one(type, fn)
event-target.js, line 112

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.
Overrides:

removeEventListener()
event-target.js, line 99

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

Overrides:
See:

trigger(event)
event-target.js, line 148

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.
