How to include js.erb file in view folder

Question

I have a JavaScript file to use with a view. There needs to be Ruby code in it, and I need to do render in Ruby, so I understand that I can\'t put the JavaScrip

Answer 1

javascript_include_tag won't work js.erb declared in the view folder itself. There are three different ways you can have the javascript.

1] Write the code in the view, i.e., in the html.erb itself.

2] Create js file in public/javascripts folder and include it using javascript_include_tag.

3] In case you want to make the request as Ajax:

• Create the js.erb in the view folder itself with the same name as that of the action.
• In the view where some form is created which will be calling this action, make the request using :remote => true.

• In the called action, use code as follows:

  def action
    respond_to do |format|
      format.js
    end
  end
  

Answer 2

you can do this by

render :partial => "myfile"

you have to keep your file in controller's view directory with name _myfile.js.erb

Now you can write your own code (js,ruby) here and probably can separate out js with javascript_include_tag to avail asset pipline

This file will be first rendered by erb engine and then as javascript.
