Hire JavaScript DevelopersYou can use local storage if you want an updated DOM after a page reload.
Here’s an example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<script src="./script.js"></script>
</head>
<body>
<nav>
<button onclick="changeRoute('home')">Home</button>
<button onclick="changeRoute('about')">About</button>
<button onclick="changeRoute('contact')">Contact</button>
</nav>
<section>
<div id="home" class="page">
<h1>Home page</h1>
</div>
<div id="about" class="page">
<h1>About page</h1>
</div>
<div id="contact" class="page">
<h1>Contact page</h1>
</div>
</section>
</body>
</html>
window.onload = function() {
const pages = document.getElementsByClassName("page");
for(const page of pages) {
page.style.display = "none";
}
document.getElementById('home').style.display = "block";
}
const changeRoute = (route) => {
const pages = document.getElementsByClassName("page");
for(const page of pages) {
page.style.display = "none";
}
const selectedPage = document.getElementById(route);
selectedPage.style.display = "block";
}
script.js
window.onload = function() {
const pages = document.getElementsByClassName("page");
for(const page of pages) {
page.style.display = "none";
}
const selectedPage = localStorage.getItem('selectedPage');
if(selectedPage) {
document.getElementById(selectedPage).style.display = "block";
}
else {
document.getElementById('home').style.display = "block";
}
}
const changeRoute = (route) => {
const pages = document.getElementsByClassName("page");
for(const page of pages) {
page.style.display = "none";
}
const selectedPage = document.getElementById(route);
localStorage.setItem('selectedPage', route);
selectedPage.style.display = "block";
}
Here, the browser knows the previous changes to the DOM. So, when we refresh the page, it will give us an updated result.
Note: Here you can also use session storage instead of local storage.
