jquery.event-mapping.coffee

jQuery.eventMapping = (object) ->
  jQuery.each object.events, (event_and_selector, handler_name) ->
    [event, selector_with_elem_name] = event_and_selector.split(' ')
    [selector, elem_name] = selector_with_elem_name.split('|')
    object.$el.on(event, selector, jQuery.proxy(object[handler_name], object))
    if elem_name? then object[elem_name] = object.$el.find(selector)

jquery.event-mapping.js

jQuery.eventMapping = function(object) {
