Question

I want to use multipul map on single page.
Here is.

<%= gmaps4rails(@json1) %>
<%= gmaps4rails(@json2) %>

Map can’t display, all map white out …
Please help if anyone knows the solution.

EDIT:

Since v1.0.0, it’s really simple to add multiple maps on the same page, see wiki.

It’s not very straight as I didn’t need this but it could be done quite easily.

first map here, it triggers the load of the necessary js files.
<%= gmaps4rails (@json1) %>

/the empty divs for second map (beware to provide the proper css)
<div id="second_container"> 
  <div id="second_map"></div>
</div>

<% content_for :scripts do %>
<script>

var counter = 0;

Gmaps4Rails.callback = function() {
  if (counter == 0){
    counter += 1;
    <%=   { "map_options" => {  
                          "container_id" => "second_container", "id" => "second_map",
                          "type" => "SATELLITE", "center_longitude" => 180, "zoom" => 3, "auto_adjust" => true 
                          },
            "markers"     => { "data" => @json2 }
          }.to_gmaps4rails(true).html_safe
    %>
   }
};
<script>
<% end %>
