Question

How would i go about adding a class to a td tag given the following table:

<table>
    <tr>
        <td id="1"></td>
        <td id="2"></td>
        <td id="3"></td>
    </tr>
</table>

I would like to add the class to the td with the id of 2. The class name in my case is td_highlight.

Have tried a few different scripts with no luck.

Thanks in advance,
Billy

Answer 1

$('#2').addClass('td_highlight');

I am not including td in the selector because all your ids (by definition) should be unique in the page.

see the relevant bit of documentation for further reference.
