CoffeeScript to add serializeObject to JQuery, converts HTML form to JSON, modified from http://jsfiddle.net/davidhong/gP9bh/

serializeObject.coffee

$.fn.serializeObject = ->
  o = Object.create(null)
  elementMapper = (element) -> 
    element.name = $.camelCase(element.name)
    return element
  appendToResult = (i, element) ->
    node = o[element.name]
    if ('undefined' != typeof node && node != null) 
      o[element.name] = if node.push then node.push(element.value) else [node, element.value]
    else 
      o[element.name] = element.value

  $.each($.map(@serializeArray(), elementMapper), appendToResult)
  return o
