为什么不创建一个具有较低 z-index 的额外标记?它比创建自定义覆盖要少,而且可以说是一种更正确的方法。(如果您按照建议创建一个带有阴影的标记图标作为图标图像的一部分,则阴影也是可点击的,这是不可取的)
createMarkerShadow = function(map, data) {
var latLng = new google.maps.LatLng(data.latitude, data.longitude);
var markerShadow = new google.maps.Marker({
clickable: false,
position: latLng,
map: map,
icon:{
url: '/frontend/img/icons/google-map-marker-shadow.svg',
//The size image file.
size: new google.maps.Size(225, 120),
//The point on the image to measure the anchor from. 0, 0 is the top left.
origin: new google.maps.Point(0, 0),
//The x y coordinates of the anchor point on the marker. e.g. If your map marker was a drawing pin then the anchor would be the tip of the pin.
anchor: new google.maps.Point(115, 82)
},
zIndex: (Math.round(latLng.lat()*-100000)<<5)-1
});
return markerShadow;
};
setMarkerShadows = function (map, locations, bound) {
for (var i = 0; i < locations.length; i++) {
var data = locations[i];
var markerShadow = createMarkerShadow(map, data);
bound.extend(markerShadow.getPosition());
}
};
bound = new google.maps.LatLngBounds();
