Target WP post class and add active class

Hi I'm trying to create tabbed content (view WP topic here https://teamtreehouse.com/forum/custom-post-types-as-content-tabs )

Question is how I create a js to get it active, because now my page only displays my last item in list.

My list items have the id:

<li><a href="publisher-<?php the_ID(); ?>"><?php the_title(); ?></a></li>

My content div generates the same one:

 <div id="publisher-<?php the_ID(); ?>">
HERE CURRENTLY COMES THE CONTENT OF THE LAST ITEM IN LIST
</div>

Now I'm trying to create a script for content tabs that targets the variable publisher-### id but have no idea how to target something that gets created dynamically.

If anyone has an idea, all help is welcome

Thanks!

I noticed you are using jQuery on the site, so that's what I will use here for my answer. I would use the Attribute Contains Prefix Selector.

$('[href|="publisher"]').click(function(event) {
    // Make it so clicking on the link not take you to a different page (default link action)
    event.preventDefault();
    // store the publisher for this link in a variable
    var publisherId = $(this).attr('href');
    // hide all other publishers div's that are showing
    $('[id|="publisher"]').hide();
    // show the div with an id that matches the href of the link that was clicked    
    $('#' + publisherId).show();              
});

Hi Colin,

Thanks for your answer. It seems to be almost what I'm looking for. Don't know what goes wrong, but it first shows the last post, when clicking another, it hides the content but doesn't pull up the post I clicked.

Could be an issue with my php?

*UPDATE

I adapted my php of the template and got it working, you my friend, are a genious! Only one thing left to fix; When I enter the page it starts of by showing all posts, then when clicking a title it does what it should. Is it possible to start off without showing any content, just a default message like 'click a publisher to find out more' ?

Thanks so much Colin!

Alright, consider this fixed I guess

I started the script with

jQuery('[id|="publisher"]').hide();

So default nothing shows and then your awesome script starts working. I just have to create a default message then.

Thanks! Had been stuck on this for a week now!

No problem! Glad we got it working!

Instead of the script you added, I would put this in the CSS:

[id|="publisher"] {
  display: none;
}

Your script works fine (obviously), but the user might see all the publisher divs if they are on a slow connection while the page loads before it hits the script. If you have them all hidden in the CSS to start with, it will prevent that.

You're right again.

Thanks so much for the help! You saved me on this one
