如何检索td输入文本框的值？

Question

在下面的表格中，点击功能（removeRow），我想检索文本框（txtTotalAmount）的值。

我写这

function removeRow(name) { 
    $(name).parent().parent().remove(); 
    var total = $(name).parent().parent().siblings().find("input .classTotalAmount").val(); 
    alert(total);// shows only undefined in alert box 
} 

这里是我的表

<table id="tblitems" cellpadding="0" cellspacing="0" border="0" class="additemtb"> 
    <tbody> 
     <tr> 
      <th>Item Name</th> 
      <th>Item Code</th> 
      <th>Unit Price</th> 
      <th>Qty</th> 
      <th>UOM</th> 
      <th>Amount</th> 
      <th>Minimal Order Qty</th> 
      <th>FOC</th> 
      <th></th> 
     </tr> 
     <tr> 
      <td></td> 
      <td></td> 
      <td></td> 
      <td></td> 
      <td></td> 
      <td></td> 
      <td></td> 
      <td></td> 
      <td style="width:90px;"> 
       <a href="javascript:void(0)" class="copy" onclick="copyRow(this);">Copy</a> 
       <a href="javascript:void(0)" class="delete" onclick="removeRow(this);">delete</a> 
       <a href="javascript:void(0)" class="add" onclick="addRows(this)">add</a> 
      </td> 
     </tr> 
     <tr> 
      <td></td> 
      <td >Total Amount</td> 
      <td> 
       <asp:TextBox ID="txtTotalAmount" CssClass="classTotalAmount number" Columns="8" runat="server" ></asp:TextBox> 
       <asp:Label ID="Label2" runat="server" CssClass="classCurrency3" /> 
      </td> 
      <td>&nbsp;</td> 
     </tr> 
    </tbody> 
</table>
