gmaps4rails: Don't show map by default and load markers with ajax

users_controller.rb

class UsersController < ApplicationController

  respond_to :html, :json

  def index
    @json = User.all.to_gmaps4rails 
    respond_with @json
  end

end

view.html.erb

<!-- create html + load js files but don't create map itself: will be done after ajax call -->
<%= gmaps({:last_map => false}) %>

<!--  button to trigger ajax call -->
<button type="button" id="ajax">Load Map</button>

<script type="text/javascript" charset="utf-8">
$(function() {

//hide the empty container
$(".map_container").hide();

$("#ajax").click(function(){

  $.getJSON('/users', function(json){
    $(".map_container").show();
    Gmaps.loadMaps();
    Gmaps.map.addMarkers(json);
  })
  })

});
</script>

Hi, how can I pass options for markers into addMarkers method?

OK, I figured out. No worries, @apneadiving

Instead of

<%= gmaps({:last_map => false}) %>

I can add options this way

<%= gmaps("markers" => {"data" =>"[]", "options" => {"randomize" => true, "max_random_distance" => 2, "do_clustering" => true}}, "map_options" => { "provider" => "google", "provider_key" => $GOOGLE_API_KEY, "auto_adjust" => true }, :last_map => false) %>

In which, I used "[]" to fill the data section

Is there a way to create the sidebar marker list with plain html?

What changes would i make to this for v2? Cant seem to get it working. Its complaining about Gmaps.loadMaps(); as undefined Function?
