Since the first line is

Coffee Script

basically a jquery $(document).ready(function () {}), we have no clue why this error shows up. Any thoughts about it? Thanks so much. javascript jquery ruby-on-rails coffeescript share|improve this question edited Jan 25 '12 at 22:15 Dylan Markow 91.2k16225174 asked Jan 25 '12 at 22:08 user938363 1,762114796 2 Wait, is this CoffeeScript? Why are you using normal JS in CoffeeScript? –Blender Jan 25 '12 at 22:11 6 js2coffee.org will be your friend –Jesse Wolgamott Jan 25 '12 at 22:21 add a comment| 2 Answers 2 active oldest votes up vote 40 down vote accepted You can't use standard JS like that in a Coffeescript file. Either rename the file to rfq.js, or convert it to coffeescript: $ -> $('#need_report').change -> if $(this).val() $('#report_language').hide() share|improve this answer edited Jan 25 '12 at 22:16 Domenic 61.5k22158225 answered Jan 25 '12 at 22:14 Dylan Markow 91.2k16225174 3 Just renamed the file to js file. Thought js can be used in coffee script without any change. Also found a site to convert the js to coffee script or vise verse. js2coffee.org thanks. –user938363 Jan 25 '12 at 23:03 Yeah

That is, until I try to include js. This error shows up all the time, and http://stackoverflow.com/questions/33375754/ruby-on-rails-js-is-broken at first deleting the line mentioned worked Showing C:/Users/1/2/app/views/layouts/application.html.erb where line #6 raised: SyntaxError: [stdin]:1:18: reserved word "function" Rails.root: C:/Users/1/2 But that doesn't fix the issue, and I need to use javascript in my project. I've tried changing <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %> to <%= javascript_include_tag 'default', 'data-turbolinks-track' => true %> but then javascript doesn't work I've tried installing node, and node works.

It doesn’t tell me a line, but when I comment out the “focus:function” part everything works, which leads me to believe that’s the culprit. How do I write the above so that it plays nicely with coffee script? function coffeescript focus share|improve this question asked Sep rails syntax error 7 at 20:58 Dave 1 1 You have the right syntax just above where you define @open_login_dialog. –mu is too short Sep 7 at 21:31 Still not working. I changed the line beginning with "focus:" to "focus = (e) ->" and got the error "SyntaxError: [stdin]:184:11: unexpected =". –Dave Sep 8 at 13:49 Well, the error says it all. You need to use : for assignment inside an object, while = is assignment to a variable. What @muistooshort meant is that you should use () -> instead of function. So the line should read focus: (e) -> –Caffeinated.tech Sep 8 at 15:34 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote accepted As per @muistooshort's comment, You need to use coffeescript function syntax, which replaces function(a,b,c) with (a,b,c) -> Secondly, you need to continue using : for assignment inside an object. I would also suggest brushing up a little on coffeescript. This is my favourite resource on the language. A linter would also help to catch these basic syntax errors. Your code can be further cleaned up: @open_login_dialog = -> opt = autoOpen: false modal: true width: 'auto' focus: -> $(this).dialog 'option', 'width', $('#loginBox').width() Explanation If you don't expect any parameters, you can leave out the () from the function definition and jus
