    How do I select div that contains "my content"?

    <table>
  <tr>
    <td class="ms-disc-bordered-noleft">
      <div class="">
        <div>some content</div>
        <div>my content</div>
      </div>
    </td>
  </tr>
</table>

    what relation does that div has with td.ms-disc-bordered-noleft?

    • first div has empty class, two divs that contain the actual content have no divs-- these divs are dynamically created.. – Athapali Commented Jan 10, 2013 at 21:58
    • Is <div class=""> important in your tricky question? – Roko C. Buljan Commented Jan 10, 2013 at 22:01
    • I have no control over the markup or i would make it more elegant.. – Athapali Commented Jan 10, 2013 at 22:03
    • Sarika, you have to really explain, do you need the last element , or containing exactly the text my content. your question is so hard to decipher – Roko C. Buljan Commented Jan 10, 2013 at 22:08

    Reset to default 5
    • $('.ms-disc-bordered-noleft div:last')
    • $('.ms-disc-bordered-noleft div:eq(2)')
    • $('.ms-disc-bordered-noleft').find('div:eq(2)');
    • or $("div:contains('my content'):last");

    return the droid...I mean div...you are looking for.

    I have a feeling that $('.ms-disc-bordered-noleft div:last') is your best option; my performance test shows that it is generally the fastest of the 4 proposals (FireFox prefers $('.ms-disc-bordered-noleft').find('div:eq(2)');).

    See http://jsfiddle/jhfrench/cfeZU for examples of the different selectors in use.

    As for the second part of your question, that div is a 'descendant' of the td.ms-disc-bordered-noleft element. More specifically, it is the child of the td's child.

    One option as second child of inner <div>:

    var div = $(".ms-disc-bordered-noleft > div > div:eq(1)");

    It's a parent node, you can traverse up an down using .parent() and .children() or .find()

    How do I select div that contains "my content"?

    $('.ms-disc-bordered-noleft').find('div').contains("my content");

    IF I did not understand well your Q. ...you can use:

    $('.ms-disc-bordered-noleft div').find('div:last');

        ^^-parent         ^^-first children  ^^-last div

    Most direct route would be:

    var div = $("div:contains('my content'):last");

    As far as the relationship to the td goes, you could start with the above and work your way back.

    var cell = div.closest('td');

    These aren't necessarily the fastest options in terms of performance, but they are the shortest code. And I like short code.

    .ms-disc-bordered-noleft div div:nth-child(2)

    or

    .ms-disc-bordered-noleft div div:last-child
