Is there any solution/library for developing an ajax and non-ajax site?

Hi all, as you may concern, there is some ppl whose browsers doesn't support ajax.
So, well thinking of develop a website, always need a no javascript version for that kind of ppl.
Is codeIgniter have some tools allow developer to do that?

Thanks.

CI itself not really, but jquery when combined with CI does... you do your site as a non-ajax site... but through the use of jquery hooks

Code:

$(#frmid).submit(function() { });

and when you load the jquery library it magically becomes a jquery driven site based on your jquery functions...
