Question

I have the next variable in my main_controller.rb:

def create:
   @token = "24vgd32"
end

in my views/create.erb, I wrote:

<%= javascript_tag do %>
   window.my_token = '<%= j @token %>';
<% end %>

by this way, I can use this variable in any of the JavaScript files that this page references.

but how can I use it in my application.js?

this is my application.js:

$(document).ready(function(){
  licensario.getLicense({
    wizardToken: my_token
  });
});

any help appreciated!

Answer 1

In your create.html.erb use this

<%= hidden_field_tag :my_token, @token, :id => 'some_field_id' %>

replace the some_field_id and my_token with desired names.

In your javascript file

$(document).ready(function(){
  token = $('#some_field_id').val();
  //use your token for any other means.
});
