Assigning active classes based on the href attributes of child <a> tags

I've created a navigation structure as follows:

<ul class="page-sidebar-menu">
  <li class="menu">        
    <a href="">
      <span class="title">Menu Item</span>
      <span class="arrow"></span>
    </a>    
    <ul class="sub-menu">
      <li>
        <a href="somehref">Sub Menu Item</a>
      </li>
    </ul>                   
  </li>
</ul>

In order to highlight the submenu link, I need to add an active class to '.submenu li'. Additionally, I want to add an active class to 'li.menu' based on the href of '.submenu li a'. I attempted to achieve this with the following code, but it's not functioning properly:

  $(function(){
    var current = location.pathname;
    current = current.substring(current.lastIndexOf('/'));
    $('.sub-menu li a').each(function(){
        var $this = $(this);
        if($this.attr('href').indexOf(current) !== -1){
            $('.sub-menu:parent').addClass('start active open'); //ISSUE
            $('.sub-menu li a:parent').addClass('active');
        }
    });

Answer №1

To correctly target the current anchor within the current iteration context, you must use this and then traverse to the desired parent element .sub-menu using .closest(). After that, add the necessary classes as follows:

 $('.sub-menu li a').each(function(){
    var $this = $(this);
    if($this.attr('href').indexOf(current) !== -1){
        $this.closest('.sub-menu').addClass('start active open'); //SOLUTION
        $this.addClass('active');
    }
});
