The noscript element represents nothing if scripting is enabled, and represents its children if scripting is disabled. It is used to present different markup to user agents that support scripting and those that don’t support scripting, by affecting how the document is parsed.
<script type="text/javascript">
//If javascript enabled then this part will work.
//Your javascript code here...
</script>
<noscript>JavaScript disabled on your browser. Please enable it.</noscript>
