button to remote

Is there a tag that is a button but acts as link_to_remote?

Check out submit_to_remote:

It seems that submit_to_remote should be appear only in a form.
But I like to put the buttons anywhere.

I didn't see an exact solution for your problem in the docs, but you
could start with button_to_function[1]
