Question

此项目使用rails + backbone-on-rails。我试过这个＆amp;那...但我仍然不能在响应回调中设置全局变量。这是我试图做的事情：
1）初始化相同位置骨架中变量的初始化

$(document).ready ->
  window.current_user = null
  Notes.initialize()

2）设置回调

  authorize: ->
    jQuery.ajax(
      type: 'POST'
      url: '/api/sessions.json'
      wait: true
      data:
        email: @get('email')
        password:  @get('password')
    ).success( (response) ->
      exports = this
      exports.current_user = response
      window.current_user = response
      `window.current_user = response`

3）并最终执行此方法：

loginUser: (e)->
    e.preventDefault()
    if !@validateField('password') && !@validateField('email')
      return false
    @model.attributes  = @readAttributes()
    @$('#errors').text()
    @model.authorize() # call a method defined above
    console.warn window.current_user
    if window.current_user
      @$('#errors').text('You\'ve successfuly logged in ' )
    else
      @$('#errors').text('Wrong email/password!')

console.warn window.current_user的输出为null
我该如何使用这个全局变量？
PS。来自服务器的响应是正确的。

$(document).ready ->
  window.current_user =
    name: ""
    company: ""
    created_at: ""
    email: ""
    facebook: ""
    id: ""
    license_id: ""
    linkedin: ""
    password_digest: ""
    phone: ""

  Notes.initialize()
