ears

An object event manager

Create a new Ears object passing in the object to be managed

earsObj = new Ears(managedObject)

Attach event handlers to events

earsObj.on 'eventName', (e) ->
    # Do stuff

ears has an alternative syntax which changes the focus from events managed by the triggering object being managed by the listening object.

earsObj.listenTo 'eventName', objToListenTo, (e) ->
    # Do stuff

You can even subscribe to all published events from an object with the "*" event name. Using "*" as the event name will mean that the attached handler will be called on every published event an object triggers. It is up to the subscribing objects event handler to filter and responed to those events.

earsObj.listenTo '*', objToListenTo, (e) ->
    case e.type
        when 'someEvent'
            # Do something
        when: 'someOtherEvent'
            # Do something else
        else:
            # default behavior

Easily trigger events on objects

earsObj.trigger 'test'

You can also pass data through the event object

earsObj.trigger 'test', evtData

Data passed through the event object is accessed through the data property.

earsSubscriber.listenTo 'eventName', earsPublisher, (evt) ->
    evt.data
