findEventEmitterElement.coffee

# Search real event emitter from `event.target`.
#
# e.g.
#   $('<div class="setter"><div><span>Button</span></div></div>')
#     .click (event) ->
#       $emitter = findEventEmitterElement(event.target, '.setter:first')
@findEventEmitterElement = (eventTarget, selector) ->
  $target = $(eventTarget).parents(selector)
  if $target.length is 1
    $target
  else if $target.length is 0
    $(eventTarget)
  else
    throw new Error "Multipul targets exist"
