how to create a popup message without getting blocked by noscript?

hi, i'm currently using this code but it's getting blocked by noscript and the page continue loading as if the code isn't there.

<script type="text/javascript">
<!--

var answer = confirm ("click on OK to continue, or CANCEL to be directed to the Yahoo site.")
if (!answer)
window.location="http://www.yahoo.com/"

// -->

Code (markup):

</script>
how can i get the same result and bypassing noscript? even with any other language?

thanks
