i trying populate google map infowindow content partial (via ajax) when map marker clicked.

apneadivings wiki post here has helped: https://github.com/apneadiving/google-maps-for-rails/wiki/adding-an-id-to-markers-and-access-them-later

i have id model instance want retrieve in marker (from source: "marker.json({ :id => user.id })"). cannot figure out how use attach listener markers click action, , put resulting html infowindow.

after create markers:

markers = handler.addmarkers(...);  _.each(markers, function(marker){   google.maps.event.addlistener(marker.getserviceobject(), 'click', function(){     $.get(expectedurl)          .done(function(data){         //only know how `data` structured         var infowindow = new google.maps.infowindow({content: 'content' });         infowindow.open( handler.getmap(), marker.getserviceobject());       })   }) });
