悬停不正确/跳转到部分 onclick wtihout 锚标签

Question

I'm making a jump tab for my portfolio website, but i'm stuck at this small feature.

<ul class="section">
   <li><span>home</span></li>
   <li><span>about</span></li>
   <li><span>project</span></li>
   <li><span>contact</span></li>
<ul>

#main .section {
    display: flex;
    flex-direction: column;
    position: fixed;
    top: 50%;
    right: 30px;
    text-align: right;
    z-index: 10;
    margin-top: -100px;
}

#main .section li {
    list-style: none;
    background-color: #fff;
    position: relative;
    width: 20px;
    height: 20px;
    border-radius: 50%;
    margin-top: 30px;
    transform: scale(1);
    transition: all ease 0.5s;
}

#main .section li:hover {
    background-color: rgb(78, 78, 78);
    transform: scale(1.5);
}

#main .section li span {
    display: block;
    position: absolute;
    width: 100px;
    height: 20px;
    text-align: right;
    right: 25px;
    color: #fff;
    text-transform: uppercase;
    opacity: 0;
}

#main .section li span:hover {
    opacity: 1;
}

First, Text is only shown when I hover on span . Text wouldn't be shown when I hover on li which is a circle. Am I missing something here?

Second, I'm stuck at the actual function which it should jump to the section. I'm trying to use scrollIntoView method, but how could I target multiple elements in one function? This is what I've been doing so far, but it sure doesn't work.

let jumpbtn = document.querySelectorAll(".section li");

function jump(){
    for(var i = 0; i < jumpbtn.length; i++){
        jumpbtn[i].addEventListener("click", function(){
            this.id.scrollIntoView({behavior: "Smooth"});
        })
    }
}

Now hover the circle to view text also :)

try this

.section li:hover span {
    opacity: 1;
}

instead of

.section li span:hover {
    opacity: 1;
}

Then I passed the class of each li in onclick() event.

<li onclick="jump(this.className)" class="home">

then, get target element by this class name having target element's id by,

function jump(TarId){
   var target = document.getElementById(TarId);
   document.getElementById(TarId).scrollIntoView({behavior: "smooth"});
}

Live Demo

 function jump(TarId){ var target = document.getElementById(TarId); document.getElementById(TarId).scrollIntoView({behavior: "smooth"}); }

 .section { display: flex; flex-direction: column; position: fixed; top: calc(25% - 100px); right: 30px; text-align: right; z-index: 10; } .section li { list-style: none; background-color: #fff; position: relative; width: 20px; height: 20px; border-radius: 50%; margin-top: 25px; transform: scale(1); transition: all ease 0.5s; } .section li:hover { background-color: rgb(78, 78, 78); transform: scale(1.5); } .section li span { display: block; position: absolute; width: 100px; height: 20px; text-align: right; right: 25px; color: #fff; text-transform: uppercase; opacity: 0; } .section li:hover span { opacity: 1; } #main{ background:#111; position:relative; height:200px; } .content{ width:100%; margin-bottom:200px; } h1{ color:#00cc00; }

 <div id="main"> <ul class="section"> <li onclick="jump(this.className)" class="home"><span>home</span></li> <li onclick="jump(this.className)" class="about"><span>about</span></li> <li onclick="jump(this.className)" class="project"><span>project</span></li> <li onclick="jump(this.className)" class="contact"><span>contact</span></li> <ul> </div> <div class="content"> <div id="home"> <h1>Home Content</h1> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Try below code snippet, it will helpful for you.

 function moveToDiv(target){ document.getElementById(target).scrollIntoView({ behavior: 'smooth' }); }

 .section{ display:block; } .section-area{ height: 300px; width: 100%; border: 10px solid red; background: gray; font-size: 30px; box-sizing:border-box; display:block; }

 <ul class="section"> <li onclick="moveToDiv('home')"><span>home</span></li> <li onclick="moveToDiv('about')"><span>about</span></li> <li onclick="moveToDiv('project')"><span>project</span></li> <li onclick="moveToDiv('contact')"><span>contact</span></li> </ul> <div class="section-area" id="home">Home</div> <div class="section-area" id="about">About</div> <div class="section-area" id="projects">Projects</div> <div class="section-area" id="contact">Contact</div>
