Google Maps: asynchronous loading with coffeescript

I’m trying to emulate this asynchronously-loaded map using coffeescript.

This is my coffeescript:

  • nodejs async nested calls
  • Race condition in JavaScript with compound assignment
  • Handling multiple call asynchronous callbacks
  • Async update of array in Angular
  • Extract inner from a span element in selenium/protractor javascript
  • angularjs: how to do fire-and-forget with $http
  • initialize = ->
      mapOptions =
        zoom: 8
        center: new google.maps.LatLng(-34.397, 150.644)
      map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions)
    loadScript = ->
      script = document.createElement("script")
      script.type = "text/javascript"
      script.src = "" + "callback=initialize"
      document.body.appendChild script
    $(window).load ->

    Which compiles to:

    (function() {
    var initialize, loadScript;
    initialize = function() {
      var map, mapOptions;
      mapOptions = {
        zoom: 8,
        center: new google.maps.LatLng(-34.397, 150.644)
      map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
    loadScript = function() {
      var script;
      script = document.createElement("script");
      script.type = "text/javascript";
      script.src = "" + "callback=initialize";
    $(window).load(function() {
      return loadScript();

    Then I get the error:

    Uncaught TypeError: Object [object global] has no method 'initialize'

    I understand that I probably need to make the initialize() method accessible to the document’s scope, but since coffeescript wraps all modules in anonymous functions what’s the best way of making this work?

    P.S. Consider giving it a more unique name.
