当我点击汉堡时，导航栏菜单不显示

问题描述 投票：0回答：1

我的代码有问题。我想制作一个响应式导航栏，但是，虽然当我点击汉堡时它变成“X”，但菜单没有显示。我真的不明白，这让我发疯。

感谢任何可以启发我的人。

HTML代码（我把JS放在HTML中）：

var typed = new Typed(".auto-type", {
    strings : ["WEB", "MOBILE", "PHP"],
    typeSpeed : 300,
    backSpeed : 300,
    loop : true
});

const hamburger = document.querySelector(".hamburger");
const navbarNav = document.querySelector(".container .navbar_nav");

hamburger.addEventListener("click", mobileMenu);

function mobileMenu() {
    hamburger.classList.toggle("active");
    navbarNav.classList.toggle("active");
}

const navLink = document.querySelectorAll(".cat");

navLink.forEach(n => n.addEventListener("click", closeMenu));

function closeMenu() {
    hamburger.classList.remove("active");
    navbarNav.classList.remove("active");
}

在 

.cat
'css 中，您将锚点设置为不显示。但你从未将它们设置为显示。

在 CSS 中，当 navbar_nav 处于活动状态时，我使用下面的内容来显示 .cat 锚点。

.navbar_nav.active .cat{
  display:block
}


var typed = new Typed(".auto-type", {
    strings : ["WEB", "MOBILE", "PHP"],
    typeSpeed : 300,
    backSpeed : 300,
    loop : true
});

const hamburger = document.querySelector(".hamburger");
const navbarNav = document.querySelector(".container .navbar_nav");

hamburger.addEventListener("click", mobileMenu);

function mobileMenu() {
    hamburger.classList.toggle("active");
    navbarNav.classList.toggle("active");
}

const navLink = document.querySelectorAll(".cat");

navLink.forEach(n => n.addEventListener("click", closeMenu));

function closeMenu() {
    hamburger.classList.remove("active");
    navbarNav.classList.remove("active");
}
* {
    right: 0;
    left: 0;
}

body {
    margin: 0;
    padding: 0;
    width: 100%;
}

}

.navbar_nav {
    display: flex;
    list-style: none;
    align-items: center;
    padding : 0 10px 0 10px;
