选择下拉菜单进行查询返回页面后菜单里显示的是默认的菜单项

 

解决：添加js代码，加载页面后就给下拉菜单一个查询时的值

<script >
function window.onload(){ 
 document.oForm.statusReport.value="<%=statusReport%>";
 }
</script>
 
<select name="statusReport" value="<%=statusReport%>">
  <option value ="" selected="selected" style="color: red">请选择</option>
<option value ="DELIVRD">接收成功</option>
<option value= "null" >接收失败</option>
</select>
