Can someone please provide me with a Javascript code snippet that accomplishes the same function

   <script>
     document.addEventListener('DOMContentLoaded', function () {
        const menuItems = document.querySelectorAll('.headmenu li');
        
        menuItems.forEach(function (menuItem) {
            menuItem.addEventListener('click', function () {
                menuItems.forEach(function (item) {
                    item.classList.remove('selectedclass');
                });
                this.classList.add('selectedclass');
            });
        });
    });
    </script>

Can you provide an alternative JavaScript code for the jQuery function above?

Answer №1

Here are some tips on using nested functions:

  • To replace $.click(), you can use Element.addEventlistener(event, callback).
  • Try Array.forEach(callback, this) instead of $.each() (though not available for all iterable types, you can "convert/cast" them).
  • For replacing $.removeClass(), consider using DOMTokenList.remove(token) (element.classlist.remove('class')).
  • Use DOMTokenList.add(token) to substitute $.addClass() (element.classlist.add('class')).

Remember: When working with callbacks, function.bind(this) may be necessary to ensure the correct context is passed.
