I want to pass the value from <%= controller.controller_name %> <%= controller.action_name %> to javascript as below
return (document.body.className += " load-done
'<%= controller.controller_name %>' '<%= controller.action_name %>'
");
but it doesn't work, can anyone advise on this?
The question is lacking information so I just guess you want to pass some data directly from the controller to your JS code. There are two "normal" ways to do this. The first is to do a direct call to the controller as a http call and return the response as a json. The second method is to pass the data as a class variable, then you can access it in the views folder from the html files. Here you can pass the variable to a div, span or whatever and access it in the JS by finding the html tag in the JS like so:
# controllers:
def some_controller_method
@temp = 'example data, could be any type'
end
# views
<%= content_tag :div, class: "some_class", data: {temp: @temp} do %>
<% end %>
# JS
$('.some_class').data('temp')
