javascript - 大家好，我正在尝试使用 js 创建一个侧滑菜单，但我遇到了这个 msg。意外的“常量”。const navSlide = () => {

问题描述

我正在尝试使用 Js 为侧面幻灯片菜单设置动画，但在验证 Js 文件时似乎存在错误。该错误表示 const 是意外错误。我在这里有点迷路了。验证 css 和 html 很好，但 js 代码不会发生任何事情。基本上我正在尝试将 .nav-active 类添加到 DOM 中，但无济于事。

const navSlide = () => {
  const burger = document.querySelector('.burger');
  const nav = document.querySelector('.navlinks');

  burger.addEventListener('click', () => {
    nav.classList.toggle('.nav-active');
  });
}
navSlide();

*{
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

nav{
  display: flex;
  justify-content: space-around;
  align-items: center;
  height: 8vh;
  font-family: 'Lato', sans-serif;
  background-color: black;
}

.logo {
  height: 8vh;
}

.logoimg{
  height: 8vh;
  width: auto;
}

.nav-links{
  display: flex;
  justify-content: space-around;
  width: 50%;
}

.nav-links li{
  list-style: none;
}

.nav-links a{
  color: white;
  text-decoration: none;
  letter-spacing: 1px;
  font-weight: 500;
  font-size: 0.75em;
}

.burger{
  display: none;
  cursor: pointer;
}

.burger div{
    width: 24px;
    height: 3px;
    background-color: white;
    margin: 5px 0;
}

@media screen and (max-width:768px){
  body{
    overflow-x: hidden;
  }
  .nav-links{
    position: absolute;
    right: 0px;
    height: 92vh;
    top: 8vh;
    background-color: black;
    display: flex;
    flex-direction: column;
    align-items: center;
    width: 50%;
    transform: translateX(100%);
    transition: transform 0.5s ease-in;
  }
  .nav-links li{
    opacity: 0;
  }
  .burger{
    display: block;
  }
}

.nav-active{
  transform: translateX(0%);
}
