在asp中，动态表单可按普通表单一样进行提交。简易的方法是设定一个固定表单的name，当有多个表单提交时，各表单数据会自动用"，"隔开，然后用split进行分割，再循环进行分别提交。如下：

以下为引用的内容：
<%@LANGUAGE="VBSCRIPT" CODEPAGE="936"%>
<script language="javascript">
function addTxtProductNameBox()
{
      var oTb = document.getElementById("TableProductName");
      var oTr = oTb.insertRow(0);
      oTr.insertCell(0).innerHTML ="<input name='txtProductName' type='text'><input type=button onclick='return delTxtProductNameBox(this)' value='删除'>"
      return false;
}
function delTxtProductNameBox(obj)
{
      obj.parentElement.parentElement.removeNode(true);
      return false;
}
</script>
<% dim rs3,sql3,productNameArray
    if productName<>"" then
    set rs3=server.CreateObject ("ADODB.RecordSet")
    sql3="select * from AmdiProduct"
    rs3.open sql3,conn,3,2
    productNameArray=split(productName,",")
    for i = 0 to ubound(productNameArray)
    rs3.addnew
    rs3("CompanyID")=companyId
    rs3("ProductName")=productNameArray(i)
    rs3.update
    next
    rs3.close
                set rs3=nothing
    end if
%>
<form name="form1" method="post" action="">
产品名称:<a href="#" onclick="addTxtProductNameBox()">添加产品名称</a>
<table id="TableProductName" border=0>
   <tr><td> </td></tr>
</table>
<input name="submit" type="submit" id="submit" value="== 提交 ==" />
</form>
