问题描述
我有一个带有页眉和页脚的HTML表:
I have an HTML table with a header and a footer:
<table id="myTable">
<thead>
<tr>
<th>My Header</th>
</tr>
</thead>
<tbody>
<tr>
<td>aaaaa</td>
</tr>
</tbody>
<tfoot>
<tr>
<td>My footer</td>
</tr>
<tfoot>
</table>
我正在尝试在tbody
中添加以下内容:
I am trying to add a row in tbody
with the following:
myTable.insertRow(myTable.rows.length - 1);
,但该行已添加到tfoot
部分.
but the row is added in the tfoot
section.
如何插入tbody
?
推荐答案
如果要在tbody
中添加一行,请获取对其的引用并调用其 insertRow
方法.
If you want to add a row into the tbody
, get a reference to it and call its insertRow
method.
var tbodyRef = document.getElementById('myTable').getElementsByTagName('tbody')[0];
// Insert a row at the end of table
var newRow = tbodyRef.insertRow();
// Insert a cell at the end of the row
var newCell = newRow.insertCell();
// Append a text node to the cell
var newText = document.createTextNode('new row');
newCell.appendChild(newText);
<table id="myTable">
<thead>
<tr>
<th>My Header</th>
</tr>
</thead>
<tbody>
<tr>
<td>initial row</td>
</tr>
</tbody>
<tfoot>
<tr>
<td>My Footer</td>
</tr>
</tfoot>
</table>
