• Support multiple inputs with same name (checkboxes usually do this).
• Cache selectors when possible
• Return values for all inputs, if checkbox or radio isn't set, the value is null

• Deactivates checkbox or radio if value is null

  $.fn.formData = function(values) {
    var form = $(this);
    var inputs = $(':input', form).get();
    var hasNewValues = typeof values == 'object';
  
    if (hasNewValues) {
      $.each(inputs, function() {
        var input = $(this);
        var value = values[this.name];
  
        if (values.hasOwnProperty(this.name)) {
          switch (this.type) {
            case 'checkbox':
              input.prop('checked', value !== null && value);
              break;
            case 'radio':
              if (value === null) {
                input.prop('checked', false);
              } else if (input.val() == value) {
                input.prop("checked", true);
              }
              break;
            default:
              input.val(value);
          }
        }
      });
      return form;
    } else {
      values = {};
      $.each(inputs, function() {
        var input = $(this);
        var value;
        switch (this.type) {
          case 'checkbox':
          case 'radio':
            value = input.is(':checked') ? input.val() : null;
            break;
          default:
            value = $(this).val();
        }
        values[this.name] = value;
      });
      return values;
    }
  };
