Rails 4 react_to javascript

Question

I have a simple PagesController with a 'homepage' method. I just want the method to respond to my homepage.js.erb template file which is containing a simple console.log("Hello World!"); So i wrote respond_to do |format| format.js format.html end respond_to do |format| format.js format.html end in my homepage method but it does nothing. ( no hello world in my chrome console ). If i remove the format.html rails throw me this error "ActionController::UnknownFormat" .

Is it a problem with turbolinks? how can i do?

Thanks JD

Answer 1

Turbolinks sends request as Html, So the js file wont get rendered but HTML one and on Client side turbolinks just replaces body with new content and updates URL.

If you want to render you js.erb file then you need to initiate js request not html. just write remote true in link_to.

Example

= link_to 'XYZ', url, :remote => true

Or if you want to execute js code on browser for HTML request then you need to write your JavaScript code inside you HTML file(format.html)

Example:

javascript:
  console.log("Hello World!");
