Steps to hide the sidenav when clicking on a hyperlink

Everything is working smoothly with the navigation, but there's a small glitch to address: the side navigation bar should close automatically when a link is clicked on this one-page website. Can anyone assist me with this issue?

Here is the code snippet:

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

function closeNav() {
  document.getElementById("mySidenav").style.width = "0";
}
.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;
}
<div id="mySidenav" class="sidenav">
  <a href="javascript:void(0)" class="closebtn" onclick="closeNav()">&times;</a>
  <a id="nav" href="#about">About</a>
  <a id="nav" href="#service">Services</a>
  <a id="nav" href="#contact">contact</a>

</div>
<p>Click to open</p>
<span style="font-size:30px;cursor:pointer" onclick="openNav()">&#9776; open</span>

The desired behavior is for the sidenav to close automatically upon clicking a link.

Answer №1

Your code is functioning perfectly. However, it appears that you just overlooked adding the closenav() function to the onclick events on the actual links.

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

function closeNav() {
  document.getElementById("mySidenav").style.width = "0";
}
.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;
}
<div id="mySidenav" class="sidenav">
  <a href="javascript:void(0)" class="closebtn" onclick="closeNav()">&times;</a>
  <a id="nav" href="#about" onclick="closeNav()">About</a>
  <a id="nav" href="#service" onclick="closeNav()">Services</a>
  <a id="nav" href="#contact" onclick="closeNav()">contact</a>

</div>
<p>Click to open</p>
<span style="font-size:30px;cursor:pointer" onclick="openNav()">&#9776; open</span>

Answer №2

Give this a try:

HTML Code:

<div id="mySidenav" class="sidenav jsSideNav">
          <a href="javascript:void(0)" class="">&times;</a>
          <a id="nav" href="#about">About</a>
          <a id="nav" href="#service">Services</a>
          <a id="nav" href="#contact">Contact</a>
    </div>
    <p>Click to open</p>
    <span style="font-size:30px;cursor:pointer" class="jsToggleNav">&#9776; Open</span>

CSS Styles:

.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.active {
    width: 250px;
}

JavaScript Functionality:

$(document).ready(function(){
        $(".jsToggleNav").on('click', function(){
            if($(".jsSideNav").hasClass('active')) {
                $(".jsSideNav").removeClass('active');
            } else {
                $(".jsSideNav").addClass('active');
            }
        })
    });

If you are using jQuery, make sure to follow the class naming convention for JavaScript operations.

Hope this solution proves helpful for your project.
