It depends on how you’ve set things up, but most likely they will see the HTML form (unless it’s generated by JS, which is unlikely), but it won’t send anything.
It’s better to use PHP for processing the form, and to add JS enhancements that are not critical.
You can use <noscript> tags, which display a message if JS is disabled. (Just Google “noscript”.) But it’s not a very nice message to receive, and it’s better not to lock out visitors like this. Aim for critical features to be accessible by all.
Ah, I agree, “noscript” tags might be your best option (more info: http://www.w3schools.com/TAGS/tag_noscript.asp )
Looks like you are answering a different question? as, maybe I’m reading it wrong, the dude up there doesn’t want to just hide its content when the script is not supported, he wants to display different content
Yes, you are right
