Warning for Non-JavaScript Browsers
If u have to do some thing important using JavaScript then you can display a warning message to the user using <noscript> tag.

You can add a noscript block immediately after the script block as follows:

<script language="javascript"   type="text/javascript">
<!--
     document.write("Hello World")
//-->

<noscript>
Sorry.....JavaScript is needed to go ahead
</noscript>

</html>

Now if the user's browser does not support JavaScript or JavaScript is not enabled then message from </noscript> will be enabled on the screen.
