切换汉堡菜单Javascript

Question

我的汉堡菜单工作不正常，也就是说，每当用户点击菜单项时，它都不会显示菜单项。然而，每当用户单击它时，它对其他功能的操作都是正确的。我已经尝试了所有可能的技巧，但我没能让它正常工作。我不确定我的javascript面临的挑战是什么，因为我认为问题是应该的。以下是我的代码：

const hamburger = document.querySelector(".hamburger");
const navbar = document.querySelector(".nav__list");
hamburger.addEventListener("click", ()=> {
navbar.classList.toggle("open");
});

const hamburgerBtn = document.querySelector('.hamburger');
let hamburgerOpen = false;
hamburgerBtn.addEventListener('click', () => {
if (!hamburgerOpen) {
hamburgerBtn.classList.add('open');
hamburgerOpen = true;
} else {
hamburgerBtn.classList.remove('open');
hamburgerOpen = false;
}
});

Answer 1

您需要从.nav__list中删除display:none，将opacity:1添加到.open，并在移动版本上编辑代码。

const hamburger = document.querySelector(".hamburger");
const navbar = document.querySelector(".nav__list");
hamburger.addEventListener("click", ()=> {
navbar.classList.toggle("open");
});

const hamburgerBtn = document.querySelector('.hamburger');
let hamburgerOpen = false;
hamburgerBtn.addEventListener('click', () => {
if (!hamburgerOpen) {
hamburgerBtn.classList.add('open');
hamburgerOpen = true;
} else {
hamburgerBtn.classList.remove('open');
hamburgerOpen = false;
}
});
