我使用gmap2开发了一个地图应用程序。我使用了地面覆盖(温度图)来帮助用户确定感兴趣的位置并单击以选择。将gmap2替换为gmap3后,它将停止工作。更大的问题是我找不到通过点击gmap3在地面覆盖上添加标记的方法。有人提出了类似的问题,但没有答案。我希望gmap3中不会丢失这样的功能。非常感谢您的帮助。
enter code here
<script>
var map;
var mapCenter = new google.maps.LatLng(54.508742, -125.120850);
var pngBounds = new google.maps.LatLngBounds(new google.maps.LatLng(48.3367, -139.0402),
new google.maps.LatLng(59.99008, -114.1095));
function initialize() {
var mapProp = { center: mapCenter, zoom: 5, mapTypeId: google.maps.MapTypeId.ROADMAP };
map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
var groundoverlay = new google.maps.GroundOverlay(
"http://www.genetics.forestry.ubc.ca/cfcg/ClimateBC40/overlays/climate/MAT_1961_1990.png", pngBounds);
groundoverlay.setMap(map);
google.maps.event.addListener(map, 'click', function (event) { placeMarker(event.latLng); });
}
function placeMarker(location) {
var marker = new google.maps.Marker({ position: location, map: map, draggable: true });
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>

在v3中,您必须使groundOverlay
不可点击
var groundoverlay = new google.maps.GroundOverlay(
"http://www.genetics.forestry.ubc.ca/cfcg/ClimateBC40/overlays/climate/MAT_1961_1990.png", pngBounds, **{clickable:false}**);

使用下面的代码就这么简单。.
let overlayGeoMapImg = new google.maps.GroundOverlay(
'../assets/GNDVI.png',
imageBounds);
overlayGeoMapImg.setMap(map);
google.maps.event.addListener(overlayGeoMapImg, 'click', (event: any) => {
this.ngZone.run(() => {
marker = new google.maps.Marker({
position: event.latLng,
map: map,
title: 'Hello World!'
});
});
});
