I have a side menu that shows up when a button is clicked, it shows up after changing its width. Everything works fine, nonetheless, I want to make the whole body (excepts from the menu) look darken, and if possible to prevent clicks in anything but the menu. When the menu is closed, all should back to normality.
The second part of the JS is used to close the menu, when detects a click outside the menu, it works but I want to make it active only if menu is open, for example:
if(menuOpen)
{
$(document).mouseup(function(e)
{
var container = $("mySidenav");
if (!container.is(e.target) && container.has(e.target).length === 0)
{
closeNav();
}
});
}
var menuOpen = false;
function openNav() {
document.getElementById("myMenu").style.width = "50%";
menuOpen = true;
}
function closeNav() {
document.getElementById("myMenu").style.width = "0%";
menuOpen = false;
}
$(document).mouseup(function(e) {
var container = $("mySidenav");
if (!container.is(e.target) && container.has(e.target).length === 0) {
closeNav();
}
});#myMenu {
height : 100%;
width : 0;
position : fixed;
z-index : 1;
top : 0;
right : 0;
background : blue;
overflow-x : hidden;
transition : 0.5s;
padding-top : 60px;
display : flex;
align-items : center;
opacity : 0.98;
z-index : 9;
color : #fff;
}<script src=".3.1/jquery.min.js"></script>

<div id="myMenu">

Reset to default 6add overlay div and toggle it's display property when menu is opened - closed
var menuOpen = false;
const menu = document.getElementById("myMenu")
const overlay = document.getElementById('overlay')
function openNav() {
menu.style.width = "50%";
menuOpen = true;
overlay.style.display = 'block'
}
function closeNav() {
menu.style.width = "0%";
overlay.style.display = 'none'
menuOpen = false;
}
$('#myMenu').click(function(e) {
closeNav();
menuOpen = false;
});#myMenu {
height: 100%;
width: 0;
position: fixed;
z-index: 1;
top: 0;
right: 0;
background: blue;
overflow-x: hidden;
transition: 0.5s;
padding-top: 60px;
display: flex;
align-items: center;
opacity: 0.98;
z-index: 9;
color: #fff;
}
#overlay {
position: fixed;
display: none;
left: 0;

<li>This is menu stuff</li>

, menuOpen = () => myMenu.classList.contains('open');
;
BtMenu.onclick = e => setMenuOpen(e, true);
myMenu.onclick = e => setMenuOpen(e, false);
// css pointer-events : none; doesn't work the same way!
document.querySelector('#overlay').onclick = e => e.stopPropagation();
function setMenuOpen(e, onOff)
{
e.preventDefault()
myMenu.classList.toggle('open',onOff)
if (e.target.matches('#myMenu li'))
{
console.log(`menu call : ${e.target.textContent }`)
setTimeout(console.clear, 2000)
}
}
// if ( menuOpen() ) { .... }#myMenu {
--mOpen : 60%; /* or 50% as yours */
height : 100%;

position : fixed;
top : 0;

display : block;
}
#myMenu.open {

}
#myMenu.open > #overlay {

#myMenu li:hover {
