Exclude Bug with Fix

[arkytn]

An old bug has reappeared in v1.4.5. When you exclude fields from saving, it also removes them from the actual form. Your previous fix method of changing getFormData() to use $.extend() doesn't work now, at least in Chrome. The extend is doing a shallow copy so all the fields are by reference. Change the workingObject and theform changes as well. Even adding extend(true,{}, theform); didn't help.

I've rewritten it so it no longer needs cloning at all. Simpler filtering routine. Removes items from the save list without affecting the original form.

    /*
    * Serialize the form data, omit excluded fields marked with data-sayt-exclude attribute.
    */
    function getFormData(theform, excludeSelectors) {
      // almost all useable clone methods pass by reference
      // so I went to a filter style fix on the DOM elements.

      excludeSelectors.push('[data-sayt-exclude]'); // Add attribute selector to the list
      $elements = theform.find(':input[name]'); //All fields with names
      $elements = $elements.not(excludeSelectors.join()); //multi select
      var form_data = $elements.serializeArray();
      return form_data;
    }
