在导航中单击 link 后菜单未关闭

Question

当我以较小的分辨率（移动分辨率）打开菜单并单击菜单中的某些 link 时，它没有关闭，它仍然存在于菜单中。你能帮助我吗？我认为 js 代码中缺少一些东西，但我不知道在单击菜单中的 link 后我还能写什么来关闭菜单。

const body = document.querySelector("body");
const navbar = document.querySelector(".navbar");
const menuBtn = document.querySelector(".menu-btn");
const cancelBtn = document.querySelector(".cancel-btn");
menuBtn.onclick = () => {
  navbar.classList.add("show");
  menuBtn.classList.add("hide");
  body.classList.add("disabled");
}
cancelBtn.onclick = () => {
  body.classList.remove("disabled");
  navbar.classList.remove("show");
  menuBtn.classList.remove("hide");
}
window.onscroll = () => {
  this.scrollY > 20 ? navbar.classList.add("sticky") : navbar.classList.remove("sticky");
}

您需要在 link 单击和取消时关闭菜单。我为此创建了一个函数以避免重复。

const body = document.querySelector("body");
const navbar = document.querySelector(".navbar");
const menuBtn = document.querySelector(".menu-btn");
const cancelBtn = document.querySelector(".cancel-btn");
const menuLinks = document.querySelectorAll('.menu-list li a');

const closeMenu = () => {
  body.classList.remove("disabled");
  navbar.classList.remove("show");
  menuBtn.classList.remove("hide");
};

menuBtn.onclick = () => {
  navbar.classList.add("show");
  menuBtn.classList.add("hide");
  body.classList.add("disabled");
};

cancelBtn.onclick = () => {
  closeMenu();
};

menuLinks.forEach(link => {
  link.onclick = () => {
    closeMenu();
  };
});

window.onscroll = () => {
  this.scrollY > 20 ? navbar.classList.add("sticky") : navbar.classList.remove("sticky");
};
