Alternative to JavaScript

HTML noscript tag

Most browsers allow users to disable JavaScript. Some browsers for simple devices or older computers do not support JavaScript. Site owners can use the noscript tag to provide content to all visitors.

Everything that is surrounded by the noscript tags will only be displayed if JavaScript is disabled or not supported by the browser.

This tutorial uses the HTML noscript tag. The noscript tag can be used to provide alternate content for users without JavaScript.

    Tools are required:

  • Text editor.
  • HTML.
  • JavaScript.
  • Browser to view output.

Optional Download and install suitable text editor

Any text editor with regular expression support will work. To select a reviewed lightweight programming editor read the Lightweight Programming Editors.

No Script Usage

JavaScript Noscript
<script type=”text/Javascript”>
document.write(“JavaScript is supported!”);
JavaScript is not supported!

JavaScript will output the statement “JavaScript is supported!”. If JavaScript is disabled or not supported, the noscript tag will output “JavaScript is not supported!.”

The noscript tag can be above the script tag since it will only be displayed if JavaScript is not working.

How to Use:

Run the Noscript.html file in your favourite browser.
Disable JavaScript in your browser and refresh the page.
Enable JavaScript in your browser and refresh the page.

Demonstration: Noscript Tutorial


HTML noscript tags can be used to display alternate content when JavaScript is not available. Instead of displaying content in a different way, most programmers prefer to warn visitors that JavaScript is disabled.


  1. Do not assume that users simple disabled JavaScript.
  2. If the website is JavaScript-heavy, a “noscript” warning is appropriate.
  3. As great as JavaScript is, do not assume users want to load several scripts.
  4. Reuse as much JavaScript as possible to keep optimal loading times.
