有一个下拉菜单，其中有一组帐号和“其他”选项。用户可以选择任何帐户，也可以使用“其他”选项输入新帐户。我有这样的代码：

      <td>1. Member Account Number<span class="bodyCopy"><font color="#ff0000"> * </font></span>: 
        <html:select name="DataForm" property="accountNumber"  styleClass="formContent"  style="width:80px" onchange="toggleField(this.value);">
         <html:options collection="<%= WorkConstants.TEST1 %>" property="value" labelProperty="label" styleClass="formContent"/>
         <option value="Other">Other </option> 
          </html:select>
         <input type="text" id="Other" value="accountNumber" name="accountNumber" style="display:none;" maxlength="9" size="9" >    
        </td>

--- Togglefield 函数如下

       <script type="text/javascript">
     function toggleField(value) 
    {var a = document.getElementById('Other');
    (value == 'Other')? a.style.display = 'block' : a.style.display = 'none';}

我的问题是， 1）当我选择其他时，文本框显示-好。但是如何将值分配给 accountNumber 呢？当我点击提交时，它没有识别出无效的帐号。 2）当页面刷新并出现验证错误时，如何保留值“other”和包含输入数字的文本框？感谢您对此的意见。

have a dropdown where i have set of account numbers and an option of "Other". user can select any account or they can user "Other" option to enter a new account. I have the code like this:

      <td>1. Member Account Number<span class="bodyCopy"><font color="#ff0000"> * </font></span>: 
        <html:select name="DataForm" property="accountNumber"  styleClass="formContent"  style="width:80px" onchange="toggleField(this.value);">
         <html:options collection="<%= WorkConstants.TEST1 %>" property="value" labelProperty="label" styleClass="formContent"/>
         <option value="Other">Other </option> 
          </html:select>
         <input type="text" id="Other" value="accountNumber" name="accountNumber" style="display:none;" maxlength="9" size="9" >    
        </td>

--- Togglefield function is as below

       <script type="text/javascript">
     function toggleField(value) 
    {var a = document.getElementById('Other');
    (value == 'Other')? a.style.display = 'block' : a.style.display = 'none';}

My question is,
1) when I select other, the text box displays- good. But how to assign the value to accountNumber ? when I click submit, it is not recognizing getting invalid account number.
2) When the page refreshes with validation errors, how do I retain value "other" and the text box with the number that is entered? appreciate your input on this.
