浅析tr的隐藏和显示问题

var ReturnrReason=function(){
 if($('#nextTransaction1 option:selected').text()=="退回制作附件"){
  $("#ReturnrReason").css('display' ,'');
  $("#ReturnrReasonNote").css('display' ,'');
  }else{
   $(":checkbox[name='workFlowParam.annexReturnReason']").attr("checked",false);//清空选项
   $("#ReturnRemarks").val("");
   $("#ReturnrReason").css('display', 'none');
   $("#ReturnrReasonNote").css('display' ,'none')
   }
}

代码：

 <tr  id="ReturnrReason" style="display: none">
   <td>附件退回原因</td>
   <td colspan="3" >
   <caf:checkboxlist name="workFlowParam.annexReturnReason" provider="simpleCode"  cssClass="required">
            <s:param name="type">210</s:param>
          </caf:checkboxlist>
 </td>
  </tr>  <tr  id="ReturnrReasonNote" style="display: none">
   <td>附件退回原因备注</td>
   <td colspan="3" >
   <textarea cols="90" id="ReturnRemarks" rows="2" name="workFlowParam.annexReturnreasonRemarks">${apprSugg.annexReturnreasonRemarks}</textarea>
 </td>
  </tr>
