Detect If Javascript Is Disabled

Hey everyone! Welcome to today’s tutorial. In this tutorial, we will learn how to detect if javascript is disabled. We will display a message if the browser does not support javascript or if the user has turned off javascript. To do this, we need just HTML. We will learn to use a special tag called .

Project Folder Structure:

Before we start to code, let us take a look at the project folder structure. We create a project folder called – Detect If Javascript Is Disabled. Inside this folder, we have two files – index.html and style.css. The first file is the HTML document, while the second one is the stylesheet.

HTML:

Let us start with the HTML. First, copy the code provided to you below and paste it into your HTML document.

The HTML contains a div with the class name – wrapper. We have to wrap all the elements inside this wrapper. For the sake of the demo, I have just used only one h1 element. The h1 tag consists of the text – Javascript is Enabled. This text will help you recognize if our code is working.

Next, we use a tag called <noscript>. Many of you might have never heard about it or used it. So let us understand what is <noscript>. Basically <noscript> will define content that we need to display in case the user has turned off javascript.

Now we use a <style> tag in which we set the display of wrapper to none. What this means is – if the browser doesn’t support javascript or if javascript is turned off by the user then simply hide everything wrapper inside the wrapper element.

We now have to set a message to be displayed if the user disables javascript. For that, we use div with the class – “msg”. Inside this div, we have the text – Javascript is Disabled.

So when the user turns off javascript, the tag will hide all the elements on the page and will display a message informing the user has turned off javascript.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Detect If Javascript Is Disabled</title>
    <!-- Google Font-->
    <link
      href="https://fonts.googleapis.com/css2?family=Poppins:wght@500&display=swap"
      rel="stylesheet"
    />
    <!-- Stylesheet -->
    <link rel="stylesheet" href="style.css" />
  </head>
  <body>
    <div class="wrapper">
      <h1>Javascript is <span>Enabled</span></h1>
    </div>
    <noscript>
      <style>
        .wrapper {
          display: none;
        }
      </style>
      <div class="msg">Javascript is <span>Disabled</span></div>
    </noscript>
  </body>
</html>

CSS:

Now for the CSS part. I have used CSS only to make the output a little bit attractive. It does not affect the functionality of the code in any way. So you can skip the CSS code. Since we do not require it, I won’t be explaining the CSS code.

* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
  font-family: "Poppins", sans-serif;
}
.wrapper,
.msg {
  position: absolute;
  transform: translate(-50%, -50%);
  top: 50%;
  left: 50%;
  text-align: center;
  font-weight: 600;
}
.wrapper h1,
.msg {
  font-size: 60px;
}
.wrapper span,
.msg span {
  color: #fc0167;
}
