Gmaps4Rails V2 setVisible

Question

I think this should be easy but every thing I try does not work. What I want to do is add code that hides markers if a review parameter is set. Unfortunately with Gmaps4Rails V2 I'm having trouble with hiding all markers.

<script src="//maps.google.com/maps/api/js?v=3.13&amp;sensor=false&amp;libraries=geometry" type="text/javascript"></script>
<script src='//google-maps-utility-library-v3.googlecode.com/svn/tags/markerclustererplus/2.0.14/src/markerclusterer_packed.js' type='text/javascript'></script>

<script src="//cdnjs.cloudflare.com/ajax/libs/underscore.js/1.6.0/underscore.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/gmaps4rails/2.1.2/gmaps4rails.js"></script>



</div>

<div style='width: 100%;'>
  <div id="map" style='width: 100%; height: 400px;'></div>
</div>

<script type="text/javascript">
handler = Gmaps.build('Google');
handler.buildMap({ provider: {}, internal: {id: 'map'}}, function(){
  if(navigator.geolocation)
    navigator.geolocation.getCurrentPosition(displayOnMap);
  markers = handler.addMarkers (<%=raw @hash.to_json %>);

  handler.bounds.extendWith(markers);
  handler.fitMapToBounds();



 _.each(markers, function(index){
   markers[index].hide();
  });


  function displayOnMap(position){
   homepostion = handler.addMarker({
    lat: position.coords.latitude,
    lng: position.coords.longitude
  });
  handler.map.centerOn(homepostion);
};
});

</script>

As always thank you in advance

All markers you get from addMarker have show and hide functions see code

If you use the clusterer, it's another story, take inspiration from the removeMarker function
