Close the sidebar menu when click on body in mobile version

Question

I have this code working perfectly for desktop version. It closes the sidenav div when clicked outside after opening it (in the body).

How should I make it work in the mobile version? It doesn't seem to recognize the javascript. Could someone help?

 function openNav() { document.getElementById("mySidenav").style.width = "250px"; } function closeNav() { document.getElementById("mySidenav").style.width = "0"; } $('body').on('click', function(){ if( parseInt( $('#mySidenav').css('width') ) > 0 ){ closeNav(); } }); 

 .sidenav { 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; } .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; } .sidenav .closebtn { position: absolute; top: 0; right: 25px; font-size: 36px; margin-left: 50px; } @media screen and (max-height: 450px) { .sidenav {padding-top: 15px;} .sidenav a {font-size: 18px;} } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="mySidenav" class="sidenav"> <a href="javascript:void(0)" class="closebtn" onclick="closeNav()">&times;</a> <a href="#">About</a> <a href="#">Services</a> <a href="#">Clients</a> <a href="#">Contact</a> </div> <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()">&#9776; open</span> <p>Click on the body area here to close the menu after opening it. However, it doesn't work on mobile version. </p>

Please try this and let me know if it works for you

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

function closeNav() {
    document.getElementById("mySidenav").style.width = "0";
}


document.addEventListener("click", function(){
  if( parseInt( $('#mySidenav').css('width') ) > 0 ){
    document.getElementById("mySidenav").style.width = "0";
  }
});

Simply adding touchstart got it to work on mobile :)

$('body').on('click touchstart', function(){
  if( parseInt( $('#mySidenav').css('width') ) > 0 ){
    closeNav();
  }
});
