HTML Include JavaScript Code in HTML Handling disabled Javascript


It is possible that the client browser does not support Javascript or have Javascript execution disabled, perhaps due to security reasons. To be able to tell users that a script is supposed to execute in the page, the <noscript> tag can be used. The content of <noscript> is displayed whenever Javascript is disabled for the current page.

  document.write("Hello, world!");
<noscript>This browser does not support Javascript.</noscript>
