Enhancing Your WordPress Menu with Customized Spans

I have a WordPress menu structured like this:

<div id="my_custom_class">
 <ul class="my_custom_class">
   <li class="page_item"><a href="#">page_item</a>
 <ul class='children'>
    <li class="page_item child"><a href="#">children</a></li>
 </ul>
   </li>
   <li class="current_page_item"><a href="#">current_page</a></li>
   <li class="current_page_item"><a href="#">current_page</a></li>
   <li class="current_page_item"><a href="#">current_page</a></li>
 </ul>
</div>

This menu is generated using:

<? wp_nav_menu('menu=header'); ?>

I want to add a <span></span> tag before the anchor tag in any li that has children, like this:

<div id="my_custom_class">
     <ul class="my_custom_class">
       <li class="page_item"><span></span><a href="#">page_item</a>
     <ul class='sub-menu'>
        <li class="page_item child"><a href="#">children</a></li>
     </ul>
       </li>
       <li class="current_page_item"><a href="#">current_page</a></li>
       <li class="current_page_item"><a href="#">current_page</a></li>
       <li class="current_page_item"><a href="#">current_page</a></li>
     </ul>

</div>

How can I achieve this using jQuery?

Answer №1

For this task, you can utilize the .prepend() method

$('ul.my_custom_class li a').closest('li').prepend('<span></span>');

Check out the Live DEMO

To see another example in action, visit this Live DEMO

$('ul.my_custom_class li:has(ul)').prepend('<span></span>');

Answer №2

If you're using jQuery, here's how you can do it:

$('<span></span>').prependTo('ul.my_custom_class li:has(ul)');

For more information, check out http://api.jquery.com/prependTo/

Answer №3

For those who prefer not to delve into the inner workings of wordpress, there is a clever way to add <span> elements using regex:

(<li.*class="[^\"]*page_item[^\"]*"[^>]*>)(<a.*</a>[^<]+<ul)

The outcome looks like this:

<div id="my_custom_class">
<ul class="my_custom_class">
<li class="page_item"><span></span><a href="#">page_item</a>
<ul class='children'>
<li class="page_item child"><a href="#">children</a></li>
</ul>
</li>
<li class="current_page_item"><a href="#">current_page</a></li>
<li class="current_page_item"><a href="#">current_page</a></li>
<li class="current_page_item"><a href="#">current_page</a></li>
</ul>
</div>

$1 = <li class="page_item">

$2 = 

<a href="#">page_item</a><ul

All you have to do now is use preg_replace with \1<span></span>\2 (don't forget to add a backslash before the </a>)

Take a look at this example on php fiddle (assuming I got the link right, haha)
