EventManager.js

A JavaScript Event Manager (add,dispatch,remove,removeAll). If you want a central place to manage events the AFTC.EventManager can help. Useful in root controllers, application logic hubs etc.

EG: http://dev.aftc.co.uk/git/AFTC.EventManager.js/tests/

Usage example 1: Adding and Dispatching (calling/firing) Events

function myEventDispatchHandler1(){ console.log("myEventDispatchHandler1(): Executed"); }
function myEventDispatchHandler2(){ console.log("myEventDispatchHandler2(): Executed"); }
EventManager.add("MyEvent",myEventDispatchHandler1);
EventManager.add("MyEvent",myEventDispatchHandler2);
EventManager.dispatch("MyEvent");

Console result:

myEventDispatchHandler1(): Executed
myEventDispatchHandler2(): Executed

Usage example 2: Adding and Removing events

function myEventDispatchHandler1(){ console.log("myEventDispatchHandler1(): Executed"); }
function myEventDispatchHandler2(){ console.log("myEventDispatchHandler2(): Executed"); }
EventManager.add("MyEvent",myEventDispatchHandler1);
EventManager.add("MyEvent",myEventDispatchHandler2);
EventManager.remove("MyEvent",myEventDispatchHandler1);
EventManager.dispatch("MyEvent");

Console result:

myEventDispatchHandler2(): Executed

Usage example 3: Cleaning a single event up

function myEventDispatchHandler1(){ console.log("myEventDispatchHandler1(): Executed"); }
function myEventDispatchHandler2(){ console.log("myEventDispatchHandler2(): Executed"); }
EventManager.add("MyEvent",myEventDispatchHandler1);
EventManager.add("MyOtherEvent",myEventDispatchHandler2);
EventManager.removeAll("MyEvent");
EventManager.dispatch("MyEvent");

Console result:

EventManager: WARNING: You are dispatching an event which doesn't exist!

Usage example 4: Cleaning everything up

function myEventDispatchHandler1(){ console.log("myEventDispatchHandler1(): Executed"); }
function myEventDispatchHandler2(){ console.log("myEventDispatchHandler2(): Executed"); }
EventManager.add("MyEvent1",myEventDispatchHandler1);
EventManager.add("MyEvent2",myEventDispatchHandler2);
EventManager.removeAll();
EventManager.dispatch("MyEvent1");
EventManager.dispatch("MyEvent2");

Console result:

EventManager: WARNING: You are dispatching an event which doesn't exist!
EventManager: WARNING: You are dispatching an event which doesn't exist!
