代码求修改~~和动态文本框的取值问题

<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
  <title></title>   
  <script type="text/javascript" language="JavaScript">   
  function ShowDiv()
  {   
  if (!document.getElementById("newdiv"))
  {
  var ndiv = document.createElement("div");
  ndiv.id="newdiv";
  ndiv.style.top="50px";
  ndiv.style.left="50px";
    
  var Obj = document.getElementById("div2").parentNode;
  Obj.appendChild(ndiv);
  }
    
  var X=document.getElementById("newdiv");
  X.innerHTML = document.getElementById("div2").innerHTML;
X.getElementsByTagName("input")[0].name="TextBox2"
  }
    
  </script>   
</head>
<body >
  <form id="form1" runat="server">   
  <div id="div1" >   
  <input id="Button1" type="button" value="button1" onclick="ShowDiv()" />   
  </div>
    
  <div id="div2">  
  <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>   
  <asp:Button ID="Button2" runat="server" Text="Button2" />
  </div>
    
  </form>
</body>
</html>
以上是代码，能动态增加一个文本框，现要求能增加5个文本框，点一次，增加一个，然后还有，这样出现的动态文本框，如何取值，跟普通的一样么？

解决方案 »

  1.   

    在JS里面取吧？一样的，通过ID来取即可，document.getElementById
      

  2.   

    给它个ID,用JS一样取值的,页面放个Hiddenfield,然后提交按键加个onclientclick
    var txtlist = document.getElementsByTagName("input");
    var names = "";
    for(var i=0;i<txtlist.length;i++){
       names+=txtlist.value+","; //把value值组合，并以','分割
    }
    //将所有的name值放入隐藏域（id=subName，name=subName）
    document.getElementById("subName").value=names; --------action----------------
    String values = request.getParameter("subName");
    String value [] = values.split(","); //这里就是所有的值了

            </div>

    添加删除功能都OK的，6楼道就只是添加了以个按钮，但是没用JS实现功能！！！

    function getValue()
        {
           var Obj = document.getElementById("divEmailS"); 
           var  txtall = Obj.getElementsByTagName("input");
           var txtShow =  document.getElementById("txtAddress"); 
           if(txtall.length>1) 
           {
               var temp;
               for(i=0;i<txtall.length;i++)
               {
                    if(i==0)
                        temp = txtall[i].value;
                    else
