<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].silkColor" value="<%=b0s0s0silkColor%>"><input id="btnAddRow1" class="btn1" 
onclick="AddStructureRowSilk()" type="button" value="+" /></td>
</tr>

</table>

<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 code form www.jb51 .net 
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
[解决办法]
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
[解决办法]
没看到其他的HTML代码，改为按照DOM关系删除应该没问题。。。

td4.innerHTML = "<input type='text' name='basicBean[0].structureBeans[structurect].silkBeans[count].silkColor'>"
+"'<input id='btnDelRow' class='btn1' type='button' value='-' onclick='DelStructureRowSilk(this)'/>";

function DelStructureRowSilk(o) {
        var structurect = document.getElementById("structureCount").value;
        structurect = parseInt(structurect) - 1;
        var count = document.getElementById("silkcount" + structurect).value;            //实现丝线表计数

        count = parseInt(count) - 1;                                                       //点击一次-1 
 
        document.getElementById("silkcount" + structurect).value = count;   //
        var obj = document.getElementById("silk" + structurect);
        o.parentNode.parentNode.parentNode.removeChild(o.parentNode.parentNode)
        //obj.deleteRow(rowIndex);

    }
