@danehansen/event-dispatcher v0.2.4

EventDispatcher

Class : public class EventDispatcher
Inheritance : EventDispatcher > Object
Subclasses : Preloader, Sprite, Timer

The EventDispatcher class is the base class for all classes that dispatch events. It is totally ripped off from the AS3 EventDispatcher, but simplified. EventDispatcher can also be used without creating an instance like singleton emitter.

Installation

npm install --save @danehansen/event-dispatcher

Usage

As a module:

import EventDispatcher from '@danehansen/event-dispatcher';
var eventDispatcher = new EventDispatcher();
eventDispatcher.addEventListener('event', onEvent);
eventDispatcher.dispatchEvent('event');

function onEvent(evt) {
  console.log('hi!');
}

In your browser:

<script src='danehansen-EventDispatcher.min.js'></script>
<script>
  var EventDispatcher = window.danehansen.EventDispatcher;
  var eventDispatcher = new EventDispatcher();
  eventDispatcher.addEventListener('event', onEvent);
  eventDispatcher.dispatchEvent('event');

  function onEvent(evt) {
    console.log('hi!');
  }
</script>
