#   <a href="http://google.com" data-mixpanel="name: 'clicked link'">Google</a>
#   <a href="http://cows.com"   data-mixpanel="name: 'clicked link', data: { animal: 'cow' }">Cow</a>
#   <li data-mixpanel="'clicked list element'">I am not a link!</li>
$(document).on "click", "[data-mixpanel]", (event) ->
  options = eval "({" + $(this).attr("data-mixpanel") + "})"

  # If event is bound to a link, add delay to ensure event is tracked.
  if event.currentTarget.href?
    options.data = {} if !options.data?
    options.data.url = event.currentTarget.href
    # Only add delay if link is being opened in this frame
    if !(event.which is 2 or event.metaKey or event.currentTarget.target is '_blank')
      event.preventDefault()
      setTimeout(->
        window.location = options.data.url
      , 300)

  mixpanel.track options.name, options.data
