width: 0;
position: fixed;
z-index: 1;
top: 0;

window.addEventListener('click', function(e){
if (!document.getElementById('mySidenav').contains(e.target) && !document.getElementById('myMenu').contains(e.target)){
// Clicked in box
document.getElementById("mySidenav").style.width = "0px";
} else{
// document.getElementById("mySidenav").style.width = "0px";
}

1) Add a click event to your body
2) Check whether the target of the click has the class '.sidenav', or if it has a parent with that class.
3) If not, hide the sidebar, for example by setting 'display' to 'none'
you can try something like this
<style>
#mySidenav {
display: none;
}
</style>
<script>
document.body.addEventListener('click', function (e) {
if (e.target.parentNode.id === 'mySidenav') {
document.getElementById("mySidenav").style.display = "block";
e.preventDefault();
return;
}
document.getElementById("mySidenav").style.display = "none";
}, true);
function openNav() {
document.getElementById("mySidenav").style.display = "block";
}

You can react on a click on the entire document element and find out whether the target is located within your menu:
document.documentElement.addEventListener("click", function(e){
if (e.button != 1) // left mouse
return; // anything else => do nothing
var target = e.target;
var navItem = document.getElementById("mySidenav");
do{
if (target == navItem)
return; // clicked within "mySidenav" => do nothing
target = target.parentNode;
}
while(target != null);
// react here
closeNav(); // must be implemented somewhere
});
It is desirable not to react at all if you detect that the click was indeed fired within your menu because otherwise you might close the menu before the click gets bubbled to the item => no menu item click detected.
function openNav() {
document.getElementById("mySidenav").style.width = "250px";
}
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
}
document.addEventListener('mousedown',function(event){
var side_dom = document.getElementById("mySidenav")
if(side_dom.style.width == '250px'){
if(!side_dom.contains(event.target)){
document.getElementById("mySidenav").style.width = "0";
}
}

I am trying to write a simple navbar pulling from the right of the screen, and I have the below code.
var isOpen = false;
function openNav() {
if (false == isOpen) {
document.getElementById("myNewsNav").style.width = "250px";
document.getElementById("main").style.marginLeft = "250px";

<h2>Sidenav Push Example</h2>
<p>Click on the element below to open the side navigation menu, and push this content to the right. Notice that we add a black see-through background-color to body when the sidenav is opened.</p>

It works fine at the left side. i tried changing the margin left and adding float: right attribute to the css, but still it isn't pulling the nav bar from the right. It always shows on the left side. What is wrong here?
EDIT:
Any which way, can I make the slider start from a specific div only?
<div id="Slider_Should_begin_From_This_Point_of_screen"></div>
Like for eg: I want the slider to slide in and out only from this div onwards.
You need to do just two things.
1) Change the marginLeft to marginRight in the function "openNav"
document.getElementById("main").style.marginRight = "250px";
2) The .newsnav css has a property "left" set to 0, you have to change that to right: 0;
.newsnav {
height: 100%;
width: 0;
position: fixed;
z-index: 1;
top: 0;
right: 0;
background-color: #111;
overflow-x: hidden;
transition: 0.5s;
padding-top: 60px;
}
That is all you have to do.
As per your updated request, it now slides from the right and below the span element:
var isOpen = false;
function openNav() {
if(isOpen == false) {
document.getElementById("myNewsNav").style.width = "250px";
//document.getElementById("main").style.marginRight = "250px";
//document.body.style.backgroundColor = "rgba(0,0,0,0.4)";
isOpen=true;
} else {
closeNav();
}
}
function closeNav() {
document.getElementById("myNewsNav").style.width = "0";
//document.getElementById("main").style.marginRight = "0";
//document.body.style.backgroundColor = "white";
isOpen=false;
}
body {
font-family: "Lato", sans-serif;
transition: background-color .5s;
}
.newsnav {
/*height: 100%;*/
width: 0;
position: relative; /* modified */
z-index: 999; /* changed to a higher number */
background-color: #111;
overflow-x: hidden;

}
.wrapper {
position: absolute; /* taken out of the document flow so that it doesn't affect other elements placed below */

Noticeable changes:
Moved the #myNewsNav div below the span element because of the document flow.
Wrapped the #myNewsNav div with an additional div
Commented out unnecessary things
You have position fixed left:0 that will keep it on the left side.

Bro - right:0 :)
.newsnav {

And replace marginLeft to marginRight in openNav() and in closeNav() functions:
document.getElementById("main").style.marginLeft = "250px";
function openNav() {
document.getElementById("myNav").style.height = "100%";
}
function closeNav() {
document.getElementById("myNav").style.height = "0%";
}
☰
You have to explain it better but I think I understand what you want.
Just use display block.
Something like this :
function openNav() {
var menu = document.getElementById("myNav").style.display;
If (menu == "block") {
menu="none";
}else{
menu="block";
}}
// Open and close div
☰
I'm not sure if the syntax is right because I'm writing this from my phone.
But I think it's works.
Lets me know.

I have implemented the following sidebar navigation into a simple admin. I've got it working and moved to the right side. I would like to have it appear and disappear using a single button rather than a separate close and open button. I tried modifying the JS with an onToggle function that if isOpen was null, it would open the panel and then set isOpen to true and then the next time it ran, it would delete isOpen. I'm very new at JS and this failed so I thought I'd ask here. How do I get this puppy appearing and disappearing with a single button?

<h2>Animated Sidenav Example</h2>
<p>Click on the element below to open the side navigation menu.</p>
<script>
function openNav() {
var e = document.getElementById("mySidenav");
if (e.style.width == '250px')
{
e.style.width = '0px';

This is the same code with little modifications in the openNav() method. For triggering the sideNavbar with a button, it needs to be visible before and after triggering the sideNavBar. So i have moved the view button to the top and i have modified the top property of sidenav to keep the trigger button visible even after activation

I know the question is tagged with JavaScript and you probably don't want to change the markup or add new elements. But if you could, here's a pure CSS solution that works.
body {
margin: 0;
}
.sidebar-toggle {
position: absolute;
left: 0;
top: 0;
z-index: 2;
padding: 10px;
background: red;
color: white;
}
#sidebar-toggle-input {
display: none;
}
#sidebar-toggle-input+label:before {
content: "➡️";
}
#sidebar-toggle-input:checked + label:before {
content: "❌"
}
.sidebar {
position: fixed;
width: 200px;
transition: 0.3s;
background: blue;
height: 100vh;
top: 0;
left: 0;
transform: translateX(-100%);
}
#sidebar-toggle-input:checked ~ .sidebar {
transform: none;
}
<input type="checkbox" id="sidebar-toggle-input" />
<label class="sidebar-toggle" for="sidebar-toggle-input"></label>
<div class="sidebar"></div>
This code will help you out, I have created a function and saving data-isshown attribute on the element, to get whether the element is shown or not, we can decide this on the basis of the width as well but this is more generic approach
function toggleNav() {
var element = document.getElementById("mySidenav")
var shown = element.getAttribute("data-isshown");
if (shown == "true") {
element.setAttribute("data-isshown", "false");
element.style.width = "0";
} else {
element.setAttribute("data-isshown", "true");
element.style.width = "250px";
}
}
Whole code would look like this
function toggleNav() {
var element = document.getElementById("mySidenav")
var shown = element.getAttribute("data-isshown");
if (shown == "true") {
element.setAttribute("data-isshown", "false");
element.style.width = "0";
} else {
element.setAttribute("data-isshown", "true");
element.style.width = "250px";
}
}
body {
font-family: "Lato", sans-serif;
}
.sidenav {
height: 100%;
width: 0;
position: fixed;
z-index: 1;
top: 0;
left: 0;
background-color: #111;
overflow-x: hidden;
transition: 0.5s;
padding-top: 60px;
}
.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;
}
.closebtn {
position: absolute;
top: 0;
right: 25px;
font-size: 36px !important;
margin-left: 50px;
}
#media screen and (max-height: 450px) {
.sidenav {
padding-top: 15px;
}
.sidenav a {
font-size: 18px;
}
}
<div id="mySidenav" class="sidenav">
