今天要實現一個在頁面中動態添加以及刪除一行列表的功能,查找了幾種方法,在此備份,以便日後使用:
========================此方法比較簡潔，而且可以解決問題========================
function deleteCurrentRow()//刪除當前行
{
var currRowIndex=event.srcElement.parentNode.parentNode.rowIndex;
document.all.table10.deleteRow(currRowIndex);//table10--表格id
}
function insertRow()
{
var nRow=document.all.table10.rows.length; //表格的總行數
var objTheRow=document.all.table10.insertRow(nRow);//在最下邊新增一行
objTheRow.insertCell(0);//新增一個單元格
objTheRow.insertCell(1);
objTheRow.insertCell(2);
objTheRow.cells(0).innerHTML=nRow;//對新增的單元格?容
objTheRow.cells(1).innerHTML=" ";
objTheRow.cells(2).innerHTML="<input type='button' value='del this row' onClick='deleteCurrentRow()'>";
}
====================我的程序代碼======================

=================================另外一種方法==============
如何刪除表格的行上次講到了如何動態給表格增加行，那麼這次就講講如何刪除表格的行了。首先建立一個表格，
<table border="1">
<tr>
<td>姓名</td>
<td>地址</td>
</tr>
<tbody id="mainbody">
<tr id="delCell">
<td>name</td>
<td>address</td>
</tr>
</tbody>
</table>
取得tbody的元素var mailbody = document.getElementById("mainbody");,
接着取得要刪除行的元素var cell = document.getElementById("delCell");
最後就是從tbody中移去要刪除的行就可以了mainbody.removeChild(cell);
完整的代碼如下：
<html>
<head>
<title>動態刪除表格的行</title>
<script type="text/javascript">
function deleteCell(){
var mailbody = document.getElementById("mainbody");
var cell = document.getElementById("delCell");
if(cell!=undefined){
mainbody.removeChild(cell);
}
}
</script>
</head>
<body>
<table border="1">
<tr>
<td>姓名</td>
<td>地址</td>
</tr>
<tbody id="mainbody">
<tr id="delCell">
<td>name</td>
<td>address</td>
</tr>
</tbody>
</table>
<input type="button" value="刪除" οnclick="deleteCell()"/>
</body>
