HTML页面：

<tr>
<td>
处罚类别：
</td>

<td>
        <html:select property="punishtype" styleClass="select_mid required" onchange="refreshDataUnit(this.value);">
                        <html:options collection="punishtypeMap" property="label" labelProperty="value" />
                             </html:select>
           </td>
<td>
处罚种类：
</td>
    
<td>
<html:select property="peanal" styleClass="select_mid required">

                   </html:select>                                     
             </td>

咋样判断不选择处罚类别，则无法选择处罚种类。若果先选择处罚种类则弹出提示框

Answer 1

jquery就可以判断啊

Answer 2

可以直接在界面上面进行判断，点击处罚种类的时候你可以进行判断，如果处罚类别没有选择这块应该给他return。
