jQuery: prev(<selector>) not working?

I'm having trouble using prev() in jQuery where it's not selecting the right element.

My HTML structure is as follows:

<section id="about">
    ...
</section>
<hr>
<section id="contact">
    ...
</section>

The "active" section is #contact. I want to select the previous section skipping over the <hr>

active = active.prev('section') doesn't seem to be working. I think I may be reading the docs wrong...

If I take out the <hr> everything works beautifully. Any ideas on how to skip the <hr> on prev()?

TIA

  • I think I may be reading the docs wrong...

    The API docs for .prev() give this description:

    Description: Get the immediately preceding sibling of each element in the set of matched elements, optionally filtered by a selector.

    So, the problem is that the hr is there and being searched by .prev(), then tested against the 'section' selector.

    Any ideas on how to skip the <hr> on prev()?

    You could call .prev() once to skip over that hr then call it again for the section:

    active = active.prev().prev('section');

    Or use .prevAll() and find the closest-preceding one (in case there are any other sections occurring before it):

    active = active.prevAll('section').first();
