Detect if JavaScript is disabled in a browser
To detect if JavaScript is disabled in a web browser, use the <noscript> tag. <noscript> tag block will be executed if JavaScript is not enabled in your browser. The HTML <noscript> tag is used to handle the browsers, which do recognize <script> tag but do not support scripting. This tag is used to display an alternate text message.
