JavaScript free alternatives to HTML forms?

Are there any?

I'm writing a web app using static html. I need to get not too complex input data like text fields and numbers.

I plan to use HTML forms to have the web page talk to the API layer and do post redirect get pattern, but should I use an alternative technology like XForms? I have never heard of it in use in my circles but figured I should ask.

No js because I want to build my app for the Firefox first, noscript folks and let any JS be just decorative / an alternative front end later on down the road.

Back end is sqlite, web tech is asp.net

Whatever your input is, I want to hear it....thanks for reading.
