Answer 1

well after struggling with jquery arrays and json ,i was able to find this best solution...this is working in all scenarios and all i need is to handle empty and null conditions,which i already did and its working the way i needed.HOPE THIS HELPS SOMEONE

my controller

def show_nearby_locations

  @nearbys = Place.near("#{params[:address]}", 5,:order => "distance",:units => :km)
  @nearbys.first(10)

end

in my view file

<%= javascript_tag do%>
 window.nearbys= <%=raw @nearbys.to_json %>;

<%end%>

this is my script inside view

function initialize() {
    var map;
    var bounds = new google.maps.LatLngBounds();
    var mapOptions = {
        mapTypeId: 'roadmap'
    };

    // Display a map on the page
    map = new google.maps.Map(document.getElementById("map-canvas-guest"), mapOptions);
    map.setTilt(45);            

    var markers=[];
    var infoWindowContent=[];
    $.each(nearbys, function(index) { 

        console.log( data[0][index].latitude,data[0][index].longitude );
        markers.push([nearbys[index]['title'], nearbys[index]['latitude'],nearbys[index]['longitude']]);
        infoWindowContent.push(['
' +
        '
'+nearbys[index]['title']+'
' +'
'+
        '
'+nearbys[index]['about']+'
' +       
         '
']);

        });   

       // Display multiple markers on a map
       var infoWindow = new google.maps.InfoWindow(), marker, i;        
      // Loop through our array of markers & place each one on the map  
      for( i = 0; i < markers.length; i++ ) {
          var position = new google.maps.LatLng(markers[i][1], markers[i][2]);
          bounds.extend(position);
          marker = new google.maps.Marker({
            position: position,
            map: map,
            title: markers[i][0]
        });

        // Allow each marker to have an info window    
        google.maps.event.addListener(marker, 'click', (function(marker, i) {
            return function() {
                infoWindow.setContent(infoWindowContent[i][0]);
                infoWindow.open(map, marker);


            }
        })(marker, i));

        // Automatically center the map fitting all markers on the screen
        map.fitBounds(bounds);

    }

    // Override our map zoom level once our fitBounds function runs (Make sure it only runs once)
    var boundsListener = google.maps.event.addListener((map), 'bounds_changed', function(event) {
        this.setZoom(14);
        google.maps.event.removeListener(boundsListener);
    });

}//initialize ends
