以下是我用了一天时间才弄好,调死人了。。。。
javascript的关键代码如下:
//在按钮所在的table下面增加一个一摸一样的table
function addRow(btIndex){
var firstRow = getRowByButton(btIndex);
var newRow = firstTable.insertRow(firstRow.rowIndex+1);
var nodes = firstRow.childNodes;
var newCell = newRow.insertCell();
newCell.colSpan=5;
newCell.innerHTML = nodes[0].innerHTML;
}
//删除按钮所在的那张table
function delRow(index){
nodetr = getRowByButton(index);
nodeta = nodetr.parentNode;
nodeta.deleteRow(nodetr.rowIndex);
}
//下面方法是根据按钮来获取按钮所在的表格(tabel)的所在行。
function getRowByButton(btIndex){
var nodetd = btIndex.parentNode;
var nodetr = nodetd.parentNode;
while (nodetr.parentNode.nodeName!="TR"){
nodetr = nodetr.parentNode;
}
nodetr = nodetr.parentNode;
return nodetr;
}
html的关键代码如下:
<table class="tableclass" cellspacing="1" id="firstTable">
<tr id="firstRow">
<td colspan="5">
<table class="tableclass" cellspacing="1">
<tr>
<td class="tdclass" width="20%">类别</td>
<td class="tdclass" width="20%">名称</td>
<td class="tdclass" width="20%">标识码</td>
<td class="tdclass" width="20%">品牌</td>
<td class="tdclass" width="20%">规格</td>
</tr>
<tr>
<td class="td1class"><html:select property="productType">
<script language="javascript">fillSelect("productType",pawntype)</script>
</html:select>
</td>
<td class="td1class"><html:text property="productArray"/></td>
<td class="td1class"><html:text property="productArray"/></td>
<td class="td1class"><html:text property="productArray"/></td>
<td class="td1class"><html:text property="productArray"/></td>
</tr>
<tr>
<td class="tdclass">形状</td>
<td class="tdclass">数量</td>
<td class="tdclass">重量</td>
<td class="tdclass">估价</td>
<td class="tdclass">典当金额</td>
</tr>
<tr>
<td class="td1class"><html:text property="productArray"/></td>
<td class="td1class"><html:text property="productArray"/></td>
<td class="td1class"><html:text property="productArray"/></td>
<td class="td1class"><html:text property="productArray"/></td>
<td class="td1class"><html:text property="productArray"/></td>
</tr>
<tr>
<td class="tdclass" colspan="5">
<input type="button" value="增加" onclick="addRow(this)"/>
<input type="button" value="修改" />
<input type="button" value="删除" onclick="delRow(this)"/>
</td>
</tr>
</table>
</td>
</tr>
大功告成了。
