求一个select box的问题,当其中一个选项被选上,页面要出现一个textfield.
这是selectbox的源码:
<td>
<select name="carrierName">
<% String selectedOrderCarrierName = requestFrmObj.getCarrierName(); %>
<option value="Toll Online" <% if(selectedOrderCarrierName.equalsIgnoreCase("Toll Online")){ %> selected <% } %>>Toll Online</option>
<option value="Toll Priority" <% if(selectedOrderCarrierName.equalsIgnoreCase("Toll Priority")){ %> selected <% } %>>Toll Priority</option>
<option value="Australia Post" <% if(selectedOrderCarrierName.equalsIgnoreCase("Australia Post")){ %> selected <% } %>>Australia Post</option>
<option value="Other" <% if(selectedOrderCarrierName.equalsIgnoreCase("Sent")){ %> selected <% } %>>Other</option>
</select>
</td>
当"other"被选中时,页面中要出现一个textfield,用来写出carriername,然后这个textfield里的carriername要能提交到javabean相对的getCarrierName中.用javascript能实现么?大家给些设计意见可以么?最好是源程序啦!!

</td>
<!--让文本框隐藏 -->
<input type="text" value="xxxxx" style="display:none;" id="inp" />
<script type="text/javascript">
//得到select对象
var selects = document.getElementById("carrierName");
//如果默认选择Other 的时候 让文本框显示
if(selects.value == 'Other'){
var inp = document.getElementById("inp");
inp.style.di
