" What's the method to this madness? Do I set up some checking to see if JS is turned on and then execute certain code accordingly?
Do I put alternate code (CF code that displays error messages) inside <noscript> tags to only run it if JS is disabled? " There may be some confusion here. When thinking about this, it is very important to keep in mind that CF runs on the server and JS runs on the client AND NEVER THE TWO SHALL MIX! This can get muddled in one's mind when thinking about dynamic JS code generation and|or AJAX. But even here, the CF code runs on the server ONLY and the JS code runs on the client ONLY. So the short answer to your last question is NO. Putting CF code inside <noscript> tags would never work. The server has no idea if JS is enables and the client would have no idea what to do with the CF code. For me the highest level of looking at this is first build your application with NO JS. Just use old fashioned server/client request/response patterns to handle the validation. This is the fall back code for when JS is disabled. A user fills out the form, it is submitted to the server, the server does the validations, if problems our found they are displayed to the user and the user is allowed to fix them and resubmit the form. Then JS enhances can be added. These can short circuit the server/clent request/response cycle. Either validates the data in the client or makes AJAX request to the server for more complex validations with hidden requests. Then either report the errors and allow correction or allow the form to be submitted to the server where the validations are repeated. Yes repeated because your server can NOT rely on the user validations happened. What I am suggesting is that it's not a big stretch to create a framework/library/system that uses one set of rules to run both the server side validation and be used to create the JS code that will run the client side validation. Just make sure that the application works correctly without this code, then if it is disabled it just falls back to the client server round trips. The cfinput/cffrom functionality in CF exactly this already, but if one wants something more universal then one will need to expand on this foundation. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Create robust enterprise, web RIAs.
