How do I update a variable outside an AJAX session? (Backbone JS / CoffeeScript)

Question

For example, I want to update my_data with the session results:

    my_data = []
    url = "/some/endpoint/"

    Session.ajax
        url: url
        type: 'get'
        success: (data) ->
          my_data = data

    console.log JSON.stringify(my_data)
    return my_data

my_data is still empty, so this is definitely not working. What is the correct way of doing this?

That is the correct way.

my_data is empty because you log it before the request has completed (it is done asynchronously after all).

You can log (or otherwise use) it inside the success callback.

Thank you. I have tried it inside the success callback, that works, however I would like to return the data outside of/after the session. Is that possible? edit// taking a look at the attached duplicated now. – Miu Mar 18 '15 at 23:28
