Add same class on select form item as selected option

This is a jQuery script for Drupal forms changing the select form class to the same as the selected option item. I use the change event on select item because Chrome doesn't allow click event on option tags.

= '$(document).ready(function() {
                       var optClass = $(this).children(":selected").attr("class");
                      $(".bj-status-selector").removeClass().addClass("form-select bj-status-selector " + optClass);
drupal_add_js($script, 'inline', 'footer');
