map_blue_1.png,_blue_2.png, 等附以下代码,但{i+1}上的一些编码错误。如何适当?

<% content_for :in_script do %>
    $("#map").gMap({ 
        markers: [
                  <% @spots.each_with_index do |spot, i| %>
                    <% if spot.geocoded? %>
                    {
                      latitude: <%= spot.lat %>,
                      longitude: <%= spot.lng %>,
                      html: "<a href= #item_<%= i + 1 %> ><strong><%=h spot.name %></strong></a>",
                      icon: { image: "<%= APP_CONFIG[:site_url] +  /images/map_blue_  + {i+1} +  .png  %>",
                              iconsize: [48, 48],
                              iconanchor: [24,48],
                              infowindowanchor: [24, 0] }
                    },
                    <% end %>
                  <% end %>
                 ],
        zoom: 12 });
