<p>The <strong class=html>NOSCRIPT</strong> element provides <em>alternate content for a client-side script</em> that was not executed. A script will fail to execute if the browser does not support the scripting language or if the user has disabled client-side scripting. <strong class=html>NOSCRIPT</strong> should follow the <strong class=html><a href="../special/script.html">SCRIPT</a></strong> element for which it provides alternate content.</p>
<div class=note>
<p>Note that most browsers will fail to render the contents of <strong class=html>NOSCRIPT</strong> if the scripting language is not supported and the user has enabled client-side scripting. Most browsers will only render <strong class=html>NOSCRIPT</strong> when the user has disabled client-side scripting.</p>
<p>Also note that Netscape Navigator2.<var>x</var> supports JavaScript1.0 but still renders all <strong class=html>NOSCRIPT</strong> content.</p>
</div>
<p>Since client-side scripts usually provide dynamic interactivity that cannot be replaced by static content, the <strong class=html>NOSCRIPT</strong> element is generally not useful. Authors should try to use client-side scripts as optional enhancements that are not integral components of the Web page. In the case of form validation, any error checking done by the client-side script should be repeated by the <abbr class=initialism title="Common Gateway Interface">CGI</abbr> script or Java servlet that handles the submission at the server.</p>
