CoffeeScript Class and jQuery

Question

I have a CoffeeScript file in which I am writing a class for interactions with an audio player but for some reason I can't get it to play nicely inside of another coffeeScript file in my Rails app.

player.coffee:

window.Player = ->
 constructor: (@player_id = "player") ->
 jw = {
 'flashplayer':"<%= asset_path('player.swf') %>"
 'controlbar': 'top'
 'autostart': 'false'
 'width':'400'
 'height':'49'
 'playlist': '[]'
 'skin':"<%= asset_path('awardfm.zip') %>"
 'dock':'false'
 'wmode':'transparent'
 }
 jwplayer(@player_id).setup(jw);
 play: (track_data) ->
 console.log track_data

player_interactions.coffee

$ ->
 jw = window.Player "player" || {}
 $('.play').click ->
 jw.play('test')

(削除) I keep getting this error: Uncaught ReferenceError: Player is not defined (削除ここまで)

Its now working with the above code samples

Answer 1

To make a class globally addressable you should prefix the name of the class with "@" (unless you are within a closure in which case you need to prefix it with "window." but you probably wouldn't want to do that anyway).

player.coffee

class @Player
 constructor: (@player = "player") ->
 ...
 play: (track_data) ->
 ... 

player_interactions.coffee

jw = new Player 

Answer 2

To access a function from one coffeescript file in another, attach the function in the top level window object then reference it in your file, window.MyClass
