用Jquery获取table中td的值

最近做项目时需要用jquery获取table下的值，在网上搜索了一下发现不错，于是就copy了一下 附件是原作者写的

jquery代码（jquery 读取table tr td值完成修改功能 ）

var $td=$(td).parents('tr').children('td');
$("#seshu").val($td.eq(0).find('input').val());
$("#jshuchudan").val($td.eq(1).find('input').val());
$("#jshuchuqi").val($td.eq(2).find('input').val());
$("#jchuantongddan").val($td.eq(3).find('input').val());
$("#jchuantongdqi").val($td.eq(4).find('input').val());
$("#schuantongddan").val($td.eq(5).find('input').val());
$("#schuantongdqi").val($td.eq(6).find('input').val());
$("#zhizuodan").val($td.eq(7).find('input').val());
$("#zhizuoqi").val($td.eq(8).find('input').val());
$("#ganbandan").val($td.eq(9).find('input').val());
$("#ganbanqi").val($td.eq(10).find('input').val());
$("#pinbandan").val($td.eq(11).find('input').val());
$("#pinbanqi").val($td.eq(12).find('input').val());
$("#jjid").val($td.eq(13).find('input').val());

$("#updateform").submit();
用Jquery获取table中td的值：

          首先建立一个如下一个两行三列的table

           <table id="tb" style="text-align: center;" width="100%" border="1PX">
                <tr> <td>A1  </td><td> A2 </td> <td>A3</td> </tr>
                <tr><td>B1</td> <td>  B2</td><td>B3</td> </tr>
           </table>

        Jquery 代码部分

              <SCRIPT type=text/javascript src="Jquery/jquery-1.4.2.js">//引入Jquery 插件不能少哦</SCRIPT>

              <SCRIPT language="javascript" type="text/javascript" >

                $(function(){
                    //使用jquery 取得table 中td里面的值
                       $("#tb td").click(function(){
                                      alert($(this).text());

                         })
           
                });</SCRIPT >

用Javascript 获取table中td的值：

      直接就写JS拉，借用上面table

      <script language="javascript" type="text/javascript">
        function GetTdValue()
        {
            //Javascript 取得table 中TD的值
            var VAL=document.getElementById("tb").rows[1].cells[1];
            alert(VAL.innerHTML)
        }
    </script>




因为这个tr需要动态增加和删除，并且获得td中的值

<script src="js/jquery-1.3.2.js" type="text/javascript"> </script>
<script type="text/javascript">
function addit(){
    var n = $("#paramTable tr:last td").eq(1).html();
    if(isNaN(n)) n = 1;
    else n++;
    $("#paramTable").append("<tr><td>name</td><td>" + n + "</td><td onclick='delit(this);'>删除</td></tr>")
}
function delit(obj){ $(obj).parent().remove();} </script>
<input type="button" onclick="addit()" value="添加">
<table border=1 id="paramTable">
<tr>
<td width=100>
参数名称
</td>
<td width=100>
对应列号
</td>
<td width=60>
是否删除
</td>
</tr>
<tr>
<td>name</td>
<td>1</td>
<td onclick="delit(this);">删除</td>
</tr>
</table>
