整洁的用户体验技巧不起作用。我该如何解决？

Question

问题

javascript 顶部的注释代码是我尝试使相关的所选按钮选项卡（在导航栏上更改颜色、获得背景等）的尝试。但是当我取消注释顶部的代码时，它不仅不起作用，而且汉堡包菜单也停止工作了！

我如何调整它才能使 class 正常工作（使所选选项卡对用户显而易见）？

我的代码

//Nav Bar!!

//Button selected gets color change

/*
const selectedNav = document.querySelectorAll('li');

selectedNav.forEach((item)=>{
    document.selectedNav.addEventListener('click', navChange)
})

function navChange(event){
    ul.forEach((item)=>{
        item.classList.remove('add-this-to-selected-section');
    })
    event.target.classList.add('add-this-to-selected-section');
}
*/

const navSlide = () =>{
    const burger = document.querySelector('.burger');
    const nav = document.querySelector('.nav-links');
    const navLinks = document.querySelectorAll('.nav-links li');

// Toggle Nav
    burger.addEventListener('click',()=>{
        nav.classList.toggle('nav-active');


    //Animate Links
    navLinks.forEach((link, index)=>{
        if(link.style.animation){
            link.style.animation = '';
        } else {
        link.style.animation = `navLinkFade 0.5s ease forwards ${index / 7 + 0.5}s`
        }
   
    })
    //Burger Animation

    burger.classList.toggle('toggle');

})

}

navSlide();

非常感谢您的帮助:)

您的 class 背景颜色是相同的，而且您的 javascript 该功能也有一些问题。应该是这样的：

const selectedNav = document.querySelectorAll('li');

const navChange = (index) => {
    selectedNav.forEach((item)=>{
        item.classList.remove('add-this-to-selected-section');
    })
    selectedNav[index].classList.add('add-this-to-selected-section');
}


selectedNav.forEach((item, index)=>{
    item.addEventListener('click', ()=> navChange(index))
})



const navSlide = () =>{
    const burger = document.querySelector('.burger');
    const nav = document.querySelector('.nav-links');
    const navLinks = document.querySelectorAll('.nav-links li');

// Toggle Nav
    burger.addEventListener('click',()=>{
        nav.classList.toggle('nav-active');


    //Animate Links
    navLinks.forEach((link, index)=>{
        if(link.style.animation){
            link.style.animation = '';
        } else {
        link.style.animation = `navLinkFade 0.5s ease forwards ${index / 7 + 0.5}s`
        }
   
    })
    //Burger Animation

    burger.classList.toggle('toggle');

})

}

navSlide();

nav{
