【中文标题】菜单的动画有啥问题？【英文标题】：What's wrong with the animation for the menu?菜单的动画有什么问题？ 【发布时间】：2022-01-13 20:53:48 【问题描述】：好吧，所以基本上我必须用 html 为学校做一个互联网站点，但只有 javascript 动画，所有代码都可以正常工作，但是当我想将我用于汉堡菜单的三行转换为带有 javascript 动画的交叉时什么都没有正在发生，我真的不知道为什么。 如果有人可以帮助我，我将一如既往地感激不尽，感谢您的阅读。

【问题讨论】：
将 .nabar 更改为 .navbar 和 const MenuIcon 。注意 JavaScript 中的小写和大写字母 是的，我这样做了，但它不起作用:( 【参考方案1】：这是您的正确代码： 失踪 ;并删除 .在 javascript 代码中上课之前。祝你好运。
const MenuIcon = document.querySelector(".hamburger-menu");
const navbar = document.querySelector(".navbar");
MenuIcon.addEventListener("click", () =>
navbar.classList.toggle("change");
