html - How do you append rows to a table using jQuery?

asked Oct 17, 2021 in Technique[技术] by 深蓝 (71.8m points)

Hi I was trying to add a row to a table using jQuery, but it is not working.
What might be the reason?

And, can I put in some value to the newly added row..?

Here is the code:

<html>
<head>
    <script type="text/javascript" src="jquery.js"></script>
    <script type="text/javascript">
        $('a').click(function() {
            $('#myTable').childs('tr').append('<tr class="child"><td>blahblah</td></tr>');
        });
    </script>
    <title></title>
</head>
<body>
    <a href="">Link</a>
    <table id="myTable">
        <tbody>
            <tr>
                <td>
                    test
                </td>
            </tr>
        </tbody>
    </table>
</body>
</html>

I'm assuming you want to add this row to the <tbody> element, and simply using append() on the <table> will insert the <tr> outside the <tbody>, with perhaps undesirable results.

$('a').click(function() {
   $('#myTable tbody').append('<tr class="child"><td>blahblah</td></tr>');
});

EDIT: Here is the complete source code, and it does indeed work: (Note the $(document).ready(function(){});, which was not present before.

<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
    $('a').click(function() {
       $('#myTable tbody').append('<tr class="child"><td>blahblah</td></tr>');
    });
});
</script>
<title></title>
</head>
<body>
<a href="javascript:void(0);">Link</a>
<table id="myTable">
  <tbody>
    <tr>
      <td>test</td>
    </tr>
  </tbody>
</table>
</body>
</html>
