How do i prevent the Side Navigation to go back when i click on a link with javascript?

Question

How do i prevent the Side Navigation to go back when i click on a link with javascript? Inside the Side Navigation i have Three links some page that are linked to other pages .So whenever i open the Navigation and click the links the side navigation closes. how can i make it to navigate trough the pages but still keep the side nav open ? mu javascript code is :

    var btn=document.getElementById("btn");


btn.onclick=function(){
    document.getElementById("left").classList.add("activeL");
};

normally i use the add class in javascript and its only for opening ! i know its maybe a silly question ,but i'm a newcomer in Javascript and thank you in advance for helping me

Answer 1

you could use a query string. so your link could be:

<a href="example.com?navopen=open">my link</a>

Js would go something like this:

let urlParams = new URLSearchParams(window.location.search);
let myParam = urlParams.get('navopen');

if (myParam === "open") {
 //add whatever class/code makes the nav open, guessing:
 document.getElementById("left").classList.add("activeL");
}

I could be more specific if you add more of your markup/code Hope this helps.
