설명

jqtransform으로 selectbox를 꾸민 후에
selectbox의 option을 추가해도 추가된 option이 selectbox에서 안 보이죠.

이 문제를 해결하기 위해선 아래 함수를 jquery.jqtransform.js 파일 안에 추가하세요.

$.fn.jqTransSelectRefresh = function(){
   return this.each(function(index){
      var $select = $(this);
      var i=$select.parent().find(‘div,ul’).remove().css(‘zIndex’);
      $select.unwrap().removeClass(‘jqTransformHidden’).jqTransSelect();
      $select.parent().css(‘zIndex’, i);
   });
}

그리고나서 이렇게 호출하면 잘 보입니다.

$(‘select’).jqTransSelectRefresh ();
