Get navigation “close” status

Copy linkTweet thisAlerts:
May 10.2020

I have a sidenav that opens and close by javascript and css. My problem is that if the navigation is closed, a refresh opens it again.

Open: <div class=”nav”>
Closed: <div class=”nav close”>

“`
hamburger.addEventListener(“click”, menu);
function menu() {
nav.classList.toggle(“close”)
subnav.classList.toggle(“close”)
}
“`

How do I get the status of the menu? Like (pseudocode):

“`
 if (nav.Class) == “close”) {
stay closed;
} else {
open;
}
“`

Thanks! But if I use - toggle("close") , how do I fetch the actual "toggled status"? Not the saved status.

if (nav.classList.contains("close") {
// nav is closed
} else {
// nav is open
}
However this will not be necessary as you know about the status:
// get previous status from local storage
if (/* previous status was closed */) {
nav.classList.add("close");
} // if status after loading is "open" no removing of the class is necessary

@sibertauthorMay 11.2020 — Thanks! Finally I got to work (I think). The main code (resizing, DOMContentLoaded etc must also be altered):

``<i>
</i>hamburger.addEventListener("click", menu);
function menu() {
var width = window.innerWidth;
if (localStorage.nav == "close") {
nav.classList.remove("close")
window.localStorage.setItem('nav', "");
if (width &lt; 768) {
subnav.classList.add("close")
window.localStorage.setItem('subnav', "close");
} else {
subnav.classList.remove("close")
window.localStorage.setItem('subnav', "");
}
} else {
nav.classList.add("close")
subnav.classList.add("close")
window.localStorage.setItem('nav', "close");
window.localStorage.setItem('subnav', "close");
}
}<i>
</i>``
