Overview

After customizing the map you want, you will be given a generated code snippet that looks something like this:

<div id="map_canvas_custom_48259" style="width:830px; height:350px" ></div>
<script type="text/javascript">
  // Line breaks inserted for readability.
  (function(d, t) {
    var g = d.createElement(t), s = d.getElementsByTagName(t)[0];
    g.src = "http://map-generator.net/en/maps/48259.js?point=New+York%2C+NY%2C+USA";
    s.parentNode.insertBefore(g, s);
  }(document, "script"));
</script>
<a class="mapgen-link" style="font:8px Arial;text-decoration:none;color:#5C5C5C;text-align: right; display: block; width: 830px;" href="http://map-generator.net/en">map-generator.net</a>

Basic Solution

If you only have one map on a single page of your application, you can get away with just adding the following to your application JS:

$(document).bind 'page:load', ->
  initializeMgMaps() if $('#mggapiloader')?

Advanced Solution

This solution handles multiple maps on the same page or on separate pages of the application.

1. Add a class to the script tag for each map you have in your application.

   <script class="init_map_generator" type="text/javascript">

2. In your application JS, create a function to unload/remove Google Maps and bind it to both the page:fetch and page:restore events.

   $(document).bind 'page:fetch', ->
     cleanMapGenerator()
   
   $(document).bind 'page:restore', ->
     cleanMapGenerator true
   
   cleanMapGenerator = (init) ->
     window.mapObjWrapper = undefined
     window.google.maps = undefined
     $('#mggapiloader').remove()
     $('[src*="google-analytics.com/ga.js"]').remove()
     $('[src*="map-generator.net"]').remove()
     $('[src*="maps.gstatic.com"]').remove()
     window.eval initMapGenerator.text() if init and (initMapGenerator = $('script.init_map_generator'))?
