Question

I’m trying to change some otherwise working code by pulling all the classes into separate files. This works for most classes, except for the part where it reads class window.Timeline. The error message reads ReferenceError: window is not defined

Any suggestions?

Answer 1

It sounds like your file containing that class isn’t getting loaded into the window context. Is it possible that it got loaded in the context of another class? Could you post some cod examples in a jsFiddle?

The pattern that I usually follow when exporting coffeescript symbols to the parent context is

exports = exports ? this
class MyClass
    someField: false
exports.MyClass = MyClass

If you are using a modern browser and know how to access the debugging console, you could put

console.log this

At the end of the file that is throwing the reference error. This will allow you to have a look to see what the this context is, which may help you troubleshoot.
