自定義谷歌地圖不縮小

Question

我有一個自定義谷歌地圖here，它有幾個固定的位置。

出於某種原因改變zoom值時，地圖上沒有縮小：

var map = new google.maps.Map(document.getElementById('map'), { 
     zoom: 8, 
     center: new google.maps.LatLng(59.265881,20.515594), 
     mapTypeId: google.maps.MapTypeId.ROADMAP, 
     mapTypeControl: false, 
     streetViewControl: false, 
     panControl: false, 
     zoomControlOptions: { 
     position: google.maps.ControlPosition.LEFT_BOTTOM 
     } 
    }); 

任何想法可能會造成的呢？

休息的腳本：

var locations = [ 
     ['html', coordinates], 
     ['html', coordinates], 
     ['html', coordinates], 
     ['html', coordinates], 
     ['html', coordinates], 
    ]; 

    // Setup the different icons and shadows 
    var iconURLPrefix = 'http://www.bridgingthebaltic.org/wp-content/themes/dante-child/images/'; 

    var icons = [ 
     iconURLPrefix + 'map_icon.png', 
     iconURLPrefix + 'map_icon.png', 
     iconURLPrefix + 'map_icon.png', 
     iconURLPrefix + 'map_icon.png', 
     iconURLPrefix + 'map_icon.png', 
     iconURLPrefix + 'map_icon.png', 
    ] 
    var icons_length = icons.length; 


    var shadow = { 
     anchor: new google.maps.Point(15,33), 
     url: iconURLPrefix + 'map_icon.png' 
    }; 

    var map = new google.maps.Map(document.getElementById('map'), { 
     zoom: 8, 
     center: new google.maps.LatLng(59.265881,20.515594), 
     mapTypeId: google.maps.MapTypeId.ROADMAP, 
     mapTypeControl: false, 
     streetViewControl: false, 
     panControl: false, 
     zoomControlOptions: { 
     position: google.maps.ControlPosition.LEFT_BOTTOM 
     } 
    }); 

    var infowindow = new google.maps.InfoWindow({ 
     maxWidth: 450 
    }); 

    var marker; 
    var markers = new Array(); 

    var iconCounter = 0; 

    // Add the markers and infowindows to the map 
    for (var i = 0; i < locations.length; i++) { 
     marker = new google.maps.Marker({ 
     position: new google.maps.LatLng(locations[i][1], locations[i][2]), 
     map: map, 
     icon : icons[iconCounter], 
     shadow: shadow 
     }); 

     markers.push(marker); 

     google.maps.event.addListener(marker, 'click', (function(marker, i) { 
     return function() { 
      infowindow.setContent(locations[i][0]); 
      infowindow.open(map, marker); 
     } 
     })(marker, i)); 

     iconCounter++; 
     // We only have a limited number of possible icon colors, so we may have to restart the counter 
     if(iconCounter >= icons_length){ 
     iconCounter = 0; 
     } 
    } 



    function AutoCenter() { 
     // Create a new viewpoint bound 
     var bounds = new google.maps.LatLngBounds(); 
     // Go through each... 
     $.each(markers, function (index, marker) { 
     bounds.extend(marker.position); 
     }); 
     // Fit these bounds to the map 
     map.fitBounds(bounds); 
    } 
    AutoCenter();

出於某種原因，該地圖不縮小時改變變焦值

原因是你的地圖上的這個代碼將導致其要始終縮放以適合計算的邊界：

function AutoCenter() { 
     // Create a new viewpoint bound 
     var bounds = new google.maps.LatLngBounds(); 
     // Go through each... 
     $.each(markers, function (index, marker) { 
     bounds.extend(marker.position); 
     }); 
     // Fit these bounds to the map 
     map.fitBounds(bounds); 
    } 

如果您希望它使用zo在地圖屬性中設置，刪除對該函數的調用。
