仅在最后一个地图上显示附近搜索的标记

Question

我正在显示彼此之下的几张地图。首先，我在每个地图上都有一个代码，这个代码变得非常大，所以我试图减少我的代码。 但是，我似乎无法得到这最后的工作。 Google附近的搜索结果始终显示在最后的地图上。有没有一种方法可以在createmarker函数中设置地图，以便将标记设置为适当的地图（地图[i]）？ 我曾尝试将所有地图存储在MarkersArray中，但无法正常工作。谢谢！

var map;

目前要覆盖变量map，infoWindow & service内循环，在结束所有变量将在最后一次迭代中分配的值。

保持不变的变量（例如，通过让他们“私”通过函数），并通过这些变量作为自变量，以callback()和createMarker()

function initialize() { 

     for (i = 2; i < locations.length - 2; i++) { 
      (function (i) { 
       var MapCenter = new google.maps.LatLng(locations[i][1], locations[i][2]), 
        MyOptions = { 
         zoom: 12, 
         center: MapCenter, 
         disableDefaultUI: true, 
         scrollwheel: false 
         }, 
        map = new google.maps.Map(document.getElementById('map' + i), MyOptions), 
        weatherLayer = new google.maps.weather.WeatherLayer({ 
         temperatureUnits: google.maps.weather.TemperatureUnit.Celsius, 
         map: map 
         }), 
        cloudLayer = new google.maps.weather.CloudLayer(), 
        infoWindow = new google.maps.InfoWindow(), 
        service = new google.maps.places.PlacesService(map), 
        request = { 
         location: MapCenter, 
         radius: 10000, 
         types: ['airport', 
          'shopping_mall', 
          'subway_station', 
          'train_station', 
          'museum', 
          'place_of_worship', 
          'zoo', 'city_hall', 
          'local_government_office' 
         ] 
        }; 
       cloudLayer.setMap(map); 
       service.nearbySearch(request, function (results, status) { 
        callback(results, status, map, infoWindow, service) 
       }); 
      }(i)) 

     }; 
    }; 

    function callback(results, status, map, infoWindow, service) { 
     if (status != google.maps.places.PlacesServiceStatus.OK) { 
      alert(status); 
      return; 
     } 
     for (var j = 0, result; result = results[j]; j++) { 
      createMarker(result, map, infoWindow, service); 
     } 
    }; 

    function createMarker(place, map, infoWindow, service) { 
     //your current code may stay as it is 
    }; 

    google.maps.event.addDomListener(window, 'load', initialize);
