根据radio判断下拉框是否禁用

<script type="text/javascript" language="javascript">
   
//    function drop_Visible(boj)
//    {
//        var drop = document.getElementById("CarOilInfo1_drop_jykh");
//        if(boj=="open")
//        {
//            drop.disabled = "";
//        }
//        else
//        {
//            drop.value= "-1";
//            drop.disabled = "none";
//        }
//    }
</script>
