在js中动态添加表格行时，怎么动态改变每一行input的name值

<table class="tableStyle" id="silk0">                         <tr>                          <%--     <td width="5%" rowspan="2" id="SilkLeft">组织丝线表</td>--%>                                                           <td width="10%">丝线序号</td>                                                           <td width="10%">丝线经纬</td>                             <td width="10%">丝线类型</td>                             <td width="10%">丝线密度</td>                             <td width="10%">丝线描述</td>                         </tr>                         <tr id="SilkRight">                             <td><input type="text" name="basicBean[0].structureBeans[0].silkBeans[0].silkId" value="<%=b0s0s0silkId%>"></td>                                                           <td><input type="text" name="basicBean[0].structureBeans[0].silkBeans[0].silkWarpOrWeft" value="<%=b0s0s0silkWarpOrWeft%>"></td>                             <td><input type="text" name="basicBean[0].structureBeans[0].silkBeans[0].silkType" value="<%=b0s0s0silkType%>"></td>                             <td><input type="text" name="basicBean[0].structureBeans[0].silkBeans[0].silkDensity" value="<%=b0s0s0silkDensity%>"></td>                             <td><input type="text" name="basicBean[0].structureBeans[0].silkBeans[0].silkColor" value="<%=b0s0s0silkColor%>"><input id="btnAddRow1" class="btn1"                                     onclick="AddStructureRowSilk()" type="button" value="+" /></td>                         </tr>                                           </table>

JavaScript code?<script language="javascript" type="text/javascript">                                  //表单操作                                  function AddStructureRowSilk()                                  {                                  var structurect=document.getElementById("structureCount").value;                //取得添加组织结构表的个数                                 structurect=parseInt(structurect)-1;                                              //转成int型                                 var count=document.getElementById("silkcount"+structurect).value;            //实现组织参数表计数                                                                   count=parseInt(count)+1;                                                       //点击一次+1                                 document.getElementById("silkcount"+structurect).value=count;                                 var obj=document.getElementById("silk"+structurect);                                  var tr= obj.rows["SilkRight"];                                  //alert(tr.rowIndex);                                  //var count=document.getElementById("SilkLeft").getAttribute("rowspan");                                  //document.getElementById("SilkLeft").setAttribute("rowSpan",parseInt(count)+1);                                  //alert(count);                                                                   //document.getElementById("silkcount1").value=count;                                 //插入行                                 var tr =obj.insertRow(tr.rowIndex+1);                                  var trId="trStructure"+tr.rowIndex;                                  tr.setAttribute("id",trId);                                                                   //<s:set var="ct" value="1"/>                                                                   var td0 = tr.insertCell(0);                                  td0.setAttribute("align","left");                                 td0.innerHTML = "<input type='text' id='count' name='basicBean[0].structureBeans[structurect].silkBeans[count].silkId' > ";                                                                    var td1 = tr.insertCell(1);                                  td1.setAttribute("align","left");                                  td1.innerHTML = "<input type='text' name='basicBean[0].structureBeans[structurect].silkBeans[count].silkWarpOrWeft'>";                                 var td2 = tr.insertCell(2);                                  td2.setAttribute("align","left");                                  td2.innerHTML = "<input type='text' name='basicBean[0].structureBeans[structurect].silkBeans[count].silkType'>";                                 var td3 = tr.insertCell(3);                                  td3.setAttribute("align","left");                                  td3.innerHTML = "<input type='text' name='basicBean[0].structureBeans[structurect].silkBeans[count].silkDensity'>";                                 var td4 = tr.insertCell(4);                                  td4.setAttribute("align","left");                                  td4.innerHTML = "<input type='text' name='basicBean[0].structureBeans[structurect].silkBeans[count].silkColor'><input id='btnDelRow' class='btn1' type='button' value='-' onclick='DelStructureRowSilk("+tr.rowIndex+")'/>";                                                                   //var input1id=document.getElementById("count").getElementsByTagName("input")[0];                                 //input1id.setAttribute("name","basicBean[0].structureBeans[0].silkBeans[count].silkId");                                 //input1id.setAttribute("id","count");                                 var id=document.getElementById("count").name;                                 document.getElementById("txt").value=id;                                 } 

其中的<input type='text' id='count' name='basicBean[0].structureBeans[structurect].silkBeans[count].silkId' >structurect和count是计数，可是我这么写input的name值不会自动改变，求问我点击添加按钮，能够让新添加的行的input的name值自动递增

写个变量记录count，然后在AddStructureRowSilk方法中添加input时name的生成从变量读取

 var structurect=document.getElementById("structureCount").value;    structurect=parseInt(structurect)-1; 
  var count=document.getElementById("silkcount"+structurect).value; 
 count=parseInt(count)+1;

你不是获得这个2个变量的值了，那不就直接连接起来就好了。。

 td0.innerHTML = "<input type='text' id='count' name='basicBean[0].structureBeans["+structurect+"].silkBeans["+count+"].silkId' > ";
