Title Body

I am trying to add some JavaScript code in my Ruby on Rails application. I have already created for me, some js.coffee files for each view in my assets. Since, I am not familiar with the CoffeeScript I just passe some ordinary JavaScript/jQuery line in the file, such as: if ($('#cart').length == 1) { $('#cart').hide("blind", {direction: "vertical" }, 1000); } $('#cart tr').not('.total_line').remove(); but the following error was thrown: Error: Parse error on line 1: Unexpected 'POST_IF' (in /home/gotqn/Aptana Projects/depot/app/assets/javascripts/carts.js.coffee) The source is pointed on Showing /home/gotqn/Aptana Projects/depot/app/views/layouts/application.html.erb where line #6 raised: and in this file on line #6 I got: <%= javascript_include_tag "application" %> I am new in Ruby on Rails, but what I suppose is happening is that I am not able to write simple JavaScript in the CoffeeScript. If this is true, can I only remove the .coffe extension and be sure that the Rails magic will work and load the file?
