此代碼的Google Map自定義標記

Question

我們使用以下代碼顯示自定義的Google地圖。 我們有一個自定義標記，我可以很高興地為其添加陰影。 我們需要在地圖上顯示自定義標記，而不是Google捆綁的紅色標記

這是我們的代碼：

<script type="text/javascript"> 

var userLocation = '< ? php echo $address; ? >';

if (GBrowserIsCompatible()) {
   var geocoder = new GClientGeocoder();
   geocoder.getLocations(userLocation, function (locations) {         
      if (locations.Placemark)
      {
         var north = locations.Placemark[0].ExtendedData.LatLonBox.north;
         var south = locations.Placemark[0].ExtendedData.LatLonBox.south;
         var east  = locations.Placemark[0].ExtendedData.LatLonBox.east;
         var west  = locations.Placemark[0].ExtendedData.LatLonBox.west;

         var bounds = new GLatLngBounds(new GLatLng(south, west), 
                                        new GLatLng(north, east));

         var map = new GMap2(document.getElementById("map_canvas"));

         map.setCenter(bounds.getCenter(), map.getBoundsZoomLevel(bounds));
         map.addOverlay(new GMarker(bounds.getCenter()));
      }
   });
}
</script> 

我已經改變了這個問題的PHP部分。

Anyhoo在此站點上查找了信息：

只是不確定在何處以及如何將他引用的代碼（在上面的鏈接中）添加到我們的代碼中。 或者，如果有更好的方法。

我現在擁有的代碼是：

<script type="text/javascript"> 

    var userLocation = '< ? php echo $address; ? >';

    if (GBrowserIsCompatible()) {
       var geocoder = new GClientGeocoder();
       geocoder.getLocations(userLocation, function (locations) {         
          if (locations.Placemark)
          {
             var north = locations.Placemark[0].ExtendedData.LatLonBox.north;
             var south = locations.Placemark[0].ExtendedData.LatLonBox.south;
             var east  = locations.Placemark[0].ExtendedData.LatLonBox.east;
             var west  = locations.Placemark[0].ExtendedData.LatLonBox.west;

             var bounds = new GLatLngBounds(new GLatLng(south, west), 
                                            new GLatLng(north, east));

             var map = new GMap2(document.getElementById("map_canvas"));

             map.setCenter(bounds.getCenter(), map.getBoundsZoomLevel(bounds));
             map.addOverlay(new GMarker(bounds.getCenter()), Icon);

             var image = new google.maps.MarkerImage(
  'images/marker.png',
  new google.maps.Size(33,50),
  new google.maps.Point(0,0),
  new google.maps.Point(17,50)
);

var shadow = new google.maps.MarkerImage(
  'images/shadow.png',
  new google.maps.Size(61,50),
  new google.maps.Point(0,0),
  new google.maps.Point(17,50)
);

var shape = {
  coord: [21,1,21,2,23,3,25,4,26,5,27,6,28,7,29,8,31,9,31,10,31,11,32,12,32,13,32,14,32,15,32,16,32,17,32,18,32,19,32,20,32,21,32,22,32,23,32,24,32,25,32,26,31,27,31,28,31,29,30,30,29,31,29,32,29,33,28,34,28,35,27,36,27,37,26,38,26,39,25,40,25,41,24,42,24,43,23,44,23,45,22,46,21,47,21,48,20,49,12,49,11,48,11,47,10,46,10,45,9,44,8,43,8,42,7,41,7,40,6,39,6,38,5,37,5,36,4,35,4,34,3,33,3,32,3,31,2,30,2,29,1,28,1,27,1,26,0,25,0,24,0,23,0,22,0,21,0,20,0,19,0,18,0,17,0,16,0,15,0,14,0,13,0,12,1,11,1,10,1,9,4,8,4,7,5,6,6,5,7,4,9,3,11,2,11,1,21,1],
  type: 'poly'
};

var marker = new google.maps.Marker({
  draggable: true,
  raiseOnDrag: false,
  icon: image,
  shadow: shadow,
  shape: shape,
  map: map,
  position: point
});
          }
       });
    }
</script> 

我有標記和陰影，但它們沒有顯示，路徑是正確的，只是不確定為什么不顯示。

[更新2]似乎您沒有注意Google Maps API的版本。 在更新的示例中，您將V2和V3 API融合在一起。 以下答案與V2 API有關-就像您在原始問題中使用的那樣。

按照鏈接頁面中的描述構建Icon，最終將得到一個代表Icon對象的Icon變量。 然后將其作為第二個參數添加到new GMarker函數中：

map.addOverlay(new GMarker(bounds.getCenter()), Icon);

更新-添加示例：

<script type="text/javascript"> 

var userLocation = '< ? php echo $address; ? >';

if (GBrowserIsCompatible()) {
   var geocoder = new GClientGeocoder();
   geocoder.getLocations(userLocation, function (locations) {         
      if (locations.Placemark)
      {
         var north = locations.Placemark[0].ExtendedData.LatLonBox.north;
         var south = locations.Placemark[0].ExtendedData.LatLonBox.south;
         var east  = locations.Placemark[0].ExtendedData.LatLonBox.east;
         var west  = locations.Placemark[0].ExtendedData.LatLonBox.west;

         var bounds = new GLatLngBounds(new GLatLng(south, west), 
                                        new GLatLng(north, east));

         var map = new GMap2(document.getElementById("map_canvas"));

          var Icon = new GIcon();
          Icon.image = "mymarker.png";
          Icon.iconSize = new GSize(20, 34);

         map.setCenter(bounds.getCenter(), map.getBoundsZoomLevel(bounds));
         map.addOverlay(new GMarker(bounds.getCenter()), Icon);
      }
   });
}
</script>
