<i class="like-unlike-btn like-btn far fa-heart"></i>

Why is my code is not working? The first click event is working fine but the second is not working Please suggest some other ways to do it.

Answer 1

You can attach the event to the main class like-unlike-btn and use toggleClass instead :

$('.like-unlike-btn').on('click', function(e) {
  $(this).toggleClass('unlike-btn like-btn');
});

.like-unlike-btn {
  color: gray;
  font-size: 2rem;
  position: absolute;
  top: 0;
  left: 10px;
  cursor: pointer;
}

.like-unlike-btn:hover {
  color: red !important;
}

.like-btn {
  color: red;
}
