从元素中获取数据属性并添加 class

Question

This jquery code works and it is in use, but somehow my items filter not working with it correctly. But somehow my vanilla js working with that filter I use.

So my question is:

How I can change this jquery code to vanilla js?

$(".cat-name .cat-link").click(function () {

    let catID = $(this).data("id"),
        $allItem = $('.category')

    let $currentItem = $('.cat[data-category=' + catID + ']');
   
    $('.cat[data-category=' + catID + ']').addClass('active');
        $allItem.not($currentItem).removeClass('active');
    
    $('.all-items').removeClass('active'); // Remove active class from "All Items" tab
   
   });

Thanks if you have time to help me!

Here is a quick answer:

• use document.querySelector() and document.querySelectorAll() to select element(s)
• use targetElement.addEventListener('click', function() {... }) to add click event
• use targetElement.className to add/remove classes
• use targetElement.getAttribute('data-...') to manage data attributes
