Blur a readonly text field because by default jQuery.blur() does not do it.

jquery.readOnlyBlur

(function($) {
$.fn.readOnlyBlur = function() {
    return this.each(function() {
      if ($(this).is('input')) {
        if ($(this).is('[readonly]')) {
          var readonly_var=$(this).attr("readonly");
          $(this).removeAttr("readonly");
          $(this).blur();
          $(this).attr("readonly",readonly_var);
        } else {
          $(this).blur();
        }
      } else {
        $(this).blur();
      }
    });
};
}(jQuery));
