Ruby on Rails Using GoogleMaps with Rails Initialize the map markers using a coffee script class
Example
Provided an App.GoogleMap coffee script class and the marker information being stored in the data-address-fields attribute of the .google_map div, the map markers can be initialized on the map like this:
# app/assets/javascripts/google_maps.js.coffee
# ...
class App.GoogleMap
# ...
markers: []
constructor: (map_div)->
# ...
@init_markers()
address_fields: ->
@map_div.data('address-fields')
init_markers: ->
self = this # to reference the instance as `self` when `this` is redefined.
self.markers = []
for address_field in self.address_fields()
marker = new google.maps.Marker {
map: self.map,
position: {
lng: address_field.longitude,
lat: address_field.latitude
},
# # or, if `position` is defined in `ProfileFields::Address#as_json`:
# position: address_field.position,
title: address_field.value
}
self.markers.push marker
To learn more about marker options, have a look at google's MarkerOptions documentation and their guide to markers.
