I imagine that you could add something like this to your various
"add to basket" forms:
<noscript><input type="hidden" name="no_javascript" value="1"></noscript>
Once you get to the checkout, you should be able to perform a JS test
like this:
[if value no_javascript]
No JS available
[else]
User has JS
[/if]
In theory. :-)
