为什么我的代码不起作用？第一个点击事件工作正常，但第二个不工作请建议其他一些方法。

Answer 1

您可以将事件附加到主事件 class like-unlike-btn 并改用 toggleClass :

$('.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;
}
