Remove dependency on jQuery

[piedoom]

As of Rails 5.1, jQuery is no longer needed and Rails UJS is available without any dependencies. It would be great to drop the jQuery dependency and just use plain JS.

Yeah, I would like that too. Pull requests welcome. :)

Getting below error, can i get a quick solution for this
$.rails.allowAction is not a function

I am using rails-ujs instead of jquery_ujs

[ncri]

@srikanthcx A quick hack would be to define $.rails.allowAction somewhere and make it return true.
