Hi I see similar questions but nothing that can help me,
I have a javascript menu, and I want to click outside the menu to close it, right now, you must click the X to close the menu, I want to be able to click anywhere on the page, outside the menu, to close the menu.

<h2>Animated Sidenav Example</h2>
<p>Click on the element below to open the side navigation menu.</p>
<span style="font-size:30px;cursor:pointer" onclick="openNav()">☰ open</span>

function openNav() {
document.getElementById("mySidenav").style.width = "250px";

You could listen for clicks and check where the target is, or just create an overlay all over the page, and use a class for the open menu, instead of manually setting the sidenav width:
function openNav() {
document.body.classList.add('sidenav-open');
}
function closeNav() {
document.body.classList.remove('sidenav-open');
}

Set up a click event listener on the document and, in the listener, check to see if the actual click came from anything that isn't the menu.

I have this code that creates a side menu.
https://jsfiddle.net/oak22424/xy1a4hqe/
And this code which closes the side menu.
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
document.getElementById("main").style.marginLeft= "0";
document.body.style.backgroundColor = "white";
}
It is created so when you click the "×" in the side menu, it will close the side pane. How can I add to this the ability to execute the same JavaScript function (called closenav) when you click anywhere but the menu area?
You can wrap the content in a "container" and then assign an event listener ('click')
let doc = document.getElementById('container');
doc.addEventListener('click', () => closeNav());
function openNav() {
document.getElementById("mySidenav").style.width = "250px";
document.getElementById("main").style.marginLeft = "250px";
document.body.style.backgroundColor = "rgba(0,0,0,0.4)";
}
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
document.getElementById("main").style.marginLeft = "0";
document.body.style.backgroundColor = "white";

You can add a "click" event listener to the part of the document that closes the side menu when the target of the event is neither the open button nor contained within the side menu itself.
document.addEventListener("click", function(e){
if (e.target.id !== "openBtn" && !document.getElementById("mySidenav").contains(e.target)) {
//Note that I added an ID to the open button
closeNav();
}
})

function openNav() {
document.getElementById("mySidenav").style.width = "250px";
document.getElementById("main").style.marginLeft = "250px";
document.body.style.backgroundColor = "rgba(0,0,0,0.4)";
}
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
document.getElementById("main").style.marginLeft = "0";
document.body.style.backgroundColor = "white";

document.addEventListener("click", function(e) {

Create backdrop that spans the whole screen, when the sidenav is open, hide it when sidenav is closed, then listen to click events on it.
So it would be something like this:
function openNav() {
document.getElementById("mySidenav").style.width = "250px";
document.getElementById("main").style.marginLeft = "250px";
document.getElementById("backdrop").style.display = 'block'
}
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
document.getElementById("main").style.marginLeft = "0";
document.body.style.backgroundColor = "white";
document.getElementById("backdrop").style.display = 'none'
}
window.onclick = (event) => {
let backDrop = document.getElementById('backdrop');
if (event.target == backDrop) {
closeNav();
}
}

You can create a mouse click listener and if the menu is showing and the mouse-x position is greater than the sidebar's rightmost point (dynamically calculated by div position, clientX, and width) then it calls the same javascript function you've already written to close.
Just put this code into your JavaScript, and I have the same sidebar on my website too, lol. w3Schools squad.
window.onclick = function(event) {
if (event.target == mysidenav) {
mysidenav.style.display = "none"; // Choose Either display:none; or Closenav()
closenav(); // Choose Either CloseNav() or display:none; I recommend closenav()
}
}
I have the following page as part of a prototype for a Web Application that I'm building, and I would like to know if there's any approach (using just CSS or JS), in order to avoid text wrapping of the paragraphs from my off-canvas menu.
I'm quite "green" on building this sort of menus and I achieved the current results with this prototype, thanks to an example from W3Schools.

If I understood you correctly, you need to set the style white-space: nowrap for the paragraph (<p>) element, to prevent text wrapping ...
p {
white-space: nowrap;
}

</div>
Rather than trying to add / remove CSS rules on the click events - try using a single function that adds / removes a class to achieve the opening / closing.
I create an open class that had the styling that you had in the js - then its just a case of adding / removing the class to allow the sidenav to open / close.
This is not how I would suggest to have it - but keeping it in touch with your original code as much as possible - I wrapped the entire thing in a div with an id of wrapper - and then said that on the click of that div (which contains the side nav and the main panel) that if the wrapper has the open class - then remove it (closing the sidenav) and if not - open it.
You will need to look at what you want to trigger the opening - I assume you don't want any click on the entire pain panel opening the side nave - but this should give you an idea on how to get a click outside of the sidenav to close it.
function toggleNav() {
var wrapper = document.getElementById("wrapper");
if(wrapper.classList.contains("open")){
wrapper.classList.remove("open")
} else {
wrapper.classList.add("open");

my question is, how to change the button Open, to be on hover and display the full sidebar. Just like in sidebar from this web: https://la24.org/games-concept many thanks before.
#OP, Yes you have to put some width on your navbar. Just like how the navbar in the link you provided. No need to use JavaScript to open it. You can do it with simple CSS:
.sidenav {
height: 100%;
width: 50px; /* Put some width to hover on. */
}
/* ON HOVER */
.sidenav:hover{
width: 250px;
}
/* The side navigation menu */
.sidenav {
height: 100%;
width: 50px;
position: fixed;
z-index: 1;
top: 0;
left: 0;
background-color: #111;
overflow-x: hidden;
padding-top: 60px;
transition: 0.5s;
}
/* ON HOVER */
.sidenav:hover{
width: 250px;
}
/* The navigation menu links */
.sidenav a {
padding: 8px 8px 8px 32px;
text-decoration: none;
font-size: 25px;
color: #818181;
display: block;
transition: 0.3s
}
.sidenav a:hover, .offcanvas a:focus{
color: #f1f1f1;

You can try mouseover method and mouseout method of jQuery to solve this problem.
For example:
$("#mySidenav").mouseover(function(){
//Your code here.
})
and
$("#mySidenav").mouseout(function(){
//Your code here.
})
You can implement using CSS also without writing javascript code. See below the code.
<div class="parent">
<button class="dropbtn">Dropdown</button>

In the code mentioned by Dang Khoa, you have to include the button in side navigation or implement the onMouseHover on your button id.
$('#menuToggle, .menu-close').on('click', function(){
$('#menuToggle').toggleClass('active');
$('body').toggleClass('body-push-toleft');
$('#theMenu').toggleClass('menu-open');
$('#menuToggle').find($(".fa")).toggleClass('fa-rotate-180');
$("body").toggleClass("active");
});
this is my javascript code for navigation menu slide form right side.It is working properly but i want to close this menu when once it is open on click or close menu click anywhere on body and toggle button?
There are lots of examples on w3schools, you can use any of them. But what I personally liked was this:
function openNav() {
document.getElementById("mySidenav").style.width = "250px";
document.getElementById("main").style.marginLeft = "250px";
document.body.style.backgroundColor = "rgba(0,0,0,0.4)";
}
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
document.getElementById("main").style.marginLeft= "0";
document.body.style.backgroundColor = "white";
}
body {
font-family: "Lato", sans-serif;
transition: background-color .5s;
}
.sidenav {
height: 100%;
width: 0;
position: fixed;
z-index: 1;
top: 0;
left: 0;
background-color: #111;
overflow-x: hidden;
transition: 0.5s;
