noscript Element
Description
The noscript element allows you to display content to
users who have disabled JavaScript or who are using a browser that
doesn't support it.
The noscript element displays content and
explains that they can't use your site or page unless they enable JavaScript.
Example
The following code shows the
noscript element set up to display a simple message.
<!DOCTYPE HTML>
<html>
<head>
<script defer src="simple2.js"></script>
<noscript>
<h1>Javascript is required!</h1>
<p>You cannot use this page without Javascript</p>
</noscript>
</head>
<body>
<p>This is a test.</p>
<a href="http://java2s.com">Visit java2s.com</a>
</body>
</html>
The remainder of the page is processed as normal, and the content elements are still displayed.
You can add multiple noscript elements to
a page.
Example 2
Youc can also redirect the user's browser to a different URL if it doesn't support
JavaScript by placing a meta element inside the noscript element.
<!DOCTYPE HTML>
<html>
<head>
<script defer src="simple2.js"></script>
<noscript>
<meta http-equiv="refresh" content="0; http://www.java2s.com"/>
</noscript>
</head>
<body>
<p>This is a test.</p>
<a href="http://java2s.com">java2s.com</a>
</body>
</html>
This will redirect the user to the www.java2s.com site when a browser that doesn't support JavaScript, or that has JavaScript disabled.
