Question

I am using CoffeeScript, Backbone.js and Google Maps API to reverse geocode a lat / lng

I have the function

  country: (origin, callback) ->
    @geocoder = new google.maps.Geocoder
    @geocoder.geocode(
        'latLng': origin,
        (results, status) => 
            if status is google.maps.GeocoderStatus.OK
              callback(result[6])
            else alert("Geocode was not successful for the following reason: " + status);
    )

When I call this I use:

@country(origin, (data) =>
   console.log(data.formatted_address)
)

btw:

origin = new google.maps.LatLng(origin_lat, origin_lng)

This does not work, it does not even seem to call it. I have the call back function under (data) but can not get it to work…

Thanks

Not sure about the overall context of your question, but I will take a stab at it anyway.

The way you’ve defined your country function, it will typically be part of an object or map. If you just want a standalone function, try:

country = (origin, callback) ->
   ...

Then when calling it, try to replace @country(...) with country(...).

Based on the comments, your call to geocode also looks wrong. You need to create an instance of GeocoderRequest and pass it instead of the 'latLng': origin pair. Unfortunately I haven’t used the Google style APIs much, so if this is your real question I’m not much use to you.
