$.fn.serializeObject = function() {
  var o = {};
  var a = this.serializeArray();

  $.each(a, function() {
    if (o[this.name] !== undefined) {
      if (!o[this.name].push) {
        o[this.name] = [o[this.name]];
      }

      o[this.name].push(this.value || '');

    } else {
      o[this.name] = this.value || '';
    }
  });

  return o;
};
