Question

I’m using gmaps4rails and really enjoying it, but, I missed setting some properties, such as:

• scrollwheel
• zoomControl
• zoomControlOptions

How could these be used?

Answer 1

There is a dedicated callback in the gem to trigger custom settings.

You could do this:

<%# your call to gmaps4rails here %>

//important: this must be AFTER the call to gmaps4rails so that the Gmaps4Rails class is known.
<% content_for :scripts do %>
<script type="text/javascript" charset="utf-8">
  Gmaps4Rails.callback = function() {
    Gmaps4Rails.map.setOptions({
      scrollwheel: false,
      zoomControl: true,
      zoomControlOptions: whatever_you_need
    }):
  };
</script>
<% end %>
