How to check if JS is enabled in Rails?

Question

JavaScript

Hello, tell me how to check if a user has JAvascript enabled in RoR?
There is a form that should be displayed if js does not work. And if it works, then the form appears in a pop-up window. Please help me make this happen.)

Answer 1

For rails, it doesn't matter. Make body class="no-js" and remove this class from the body in javascript. then make the form display:none, and for the form that is inside the .no-js class, make display:block;
and done

Answer 2

The easiest way, as old as IE, is the noscript tag .
