Toggling Element Classes in Pure JavaScript

Q: How to toggle an element's class in pure JavaScript without jQuery?

jQuery's toggleClass method provides an easy way to toggle the classes of an element. But how can this be achieved using pure JavaScript?

A:

1. document.classList.toggle():

   Modern browsers support the classList.toggle method, which simplifies class manipulation. For example:

   <code class="js">var menu = document.querySelector('.container-fluid');
   menu.classList.toggle('menu-hidden');</code>

2. classList.js:

   For older browsers that lack classList.toggle, you can use the classList.js polyfill:

   <code class="js">var menu = document.querySelector('.menu');
   classList.toggle(menu, 'hidden-phone');</code>

Additional Notes:

• Class List: Use class names instead of IDs for improved efficiency.
• Avoid IDs: IDs create global variables in the JavaScript window object.
