[英]google map custom marker for this code
我们使用以下代码显示自定义的Google地图。 我们有一个自定义标记,我可以很高兴地为其添加阴影。 我们需要在地图上显示自定义标记,而不是Google捆绑的红色标记
这是我们的代码:
<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>
我已经改变了这个问题的PHP部分。
Anyhoo在此站点上查找了信息:
http://econym.org.uk/gmap/custom.htm
只是不确定在何处以及如何将他引用的代码(在上面的链接中)添加到我们的代码中。 或者,如果有更好的方法。
我现在拥有的代码是:
<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>
我有标记和阴影,但它们没有显示,路径是正确的,只是不确定为什么不显示。
[更新2]似乎您没有注意Google Maps API的版本。 在更新的示例中,您将V2和V3 API融合在一起。 以下答案与V2 API有关-就像您在原始问题中使用的那样。
按照链接页面中的描述构建Icon,最终将得到一个代表Icon对象的Icon变量。 然后将其作为第二个参数添加到new GMarker
函数中:
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>
