Question

I have a table I’m working with that is like such:

<table width="100%" border="0" cellspacing="0" cellpadding="0" id="tablecontent">
  <tr class="tablerow">
    <td>This is the td I want to add a class to.</td>
    <td class="cell2">Stuff</td>
    <td class="cell3">Stuff</td>
  </tr>
  <tr class="tablerow">
    <td>This is the td I want to add a class to.</td>
    <td class="cell2">Stuff</td>
    <td class="cell3">Stuff</td>
  </tr>
</table>

The first TD tag in each row does not have a class or ID to work with. I don’t have access to change the HTML output so I figured to add in a bit of jQuery to target the first TD tag of each tablerow. How would I do this?

Answer 1

$('#tablecontent td:first-child').addClass('someClass');

This uses the first-child selector to select all <td> elements in the #tablecontent table that are a first-child of their parent.
