Question

I have a table row, and within that, I have a td (whatever it stands for). I would like to change the class attribute of the TR my TD is in without using an ID or a name. Like that:

<tr>
    <td onclick="[TR].setAttribute('class', 'newName')">My TD</td>
</tr>

How do I do it?

Answer 1

td stands for table data..

now .. in your case you need the parentNode property of the td ..

<tr>
<td onclick="this.parentNode.setAttribute('class', 'newName')">My TD</td>
</tr>

or as bobince suggested in his comment

<td onclick="this.parentNode.className= 'newName'">My TD</td>
