I am implementing in a page a google map where a place id is passed to me, I then need to obtain such place id and load the map with that marker. I was going through the documentation but its not clear on how i can target the map object from the <agm-map>
tag so that i can set the place id. Here is part of the code:
public latitude: number;
public longitude: number;
public zoom: number;
public placeid: string;
constructor(
private mapsAPILoader: MapsAPILoader,
private ngZone: NgZone
) {}
ngOnInit() {
//set google maps defaults
this.zoom = 4;
this.latitude = 39.8282;
this.longitude = -98.5795;
this.placeid = "ChIJMS2FahDQzRIRcJqX_aUZCAQ";
//set current position
this.setCurrentPosition();
this.mapsAPILoader.load().then(() => {
//How do i set the agm-map here to load the map with the placeid
});
}
private setCurrentPosition() {
if ("geolocation" in navigator) {
navigator.geolocation.getCurrentPosition((position) => {
this.latitude = position.coords.latitude;
this.longitude = position.coords.longitude;
this.zoom = 12;
});
}
}
Then on the html file I have something like this:
<agm-map [latitude]="latitude" [longitude]="longitude" [scrollwheel]="false" [zoom]="zoom">
<agm-marker [latitude]="latitude" [longitude]="longitude"></agm-marker>
</agm-map>
I looked at the GOOGLE documentation and it looks like to set the place id you would need something like this
var request = {
placeId: 'ChIJN1t_tDeuEmsRUsoyG83frY4'
};
service = new google.maps.places.PlacesService(map);
service.getDetails(request, callback);
function callback(place, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
createMarker(place);
}
}
The problem i have is that i am not sure as to what to pass for map
since i am using <agm-map>
.
You can use mapReady
output property of agm-map
. Change your html to
<agm-map [latitude]="latitude" [longitude]="longitude" [scrollwheel]="false" [zoom]="zoom" (mapReady)="mapReady($event)">
<agm-marker [latitude]="latitude" [longitude]="longitude"></agm-marker>
</agm-map>
and define following functions in your component. This function will be called when your map is ready.
mapReady($event: any) {
// here $event will be of type google.maps.Map
// and you can put your logic here to get lat lng for marker. I have just put a sample code. You can refactor it the way you want.
this.getLatLong('ChIJN1t_tDeuEmsRUsoyG83frY4', $event, null);
}
getLatLong(placeid: string, map: any, fn) {
let placeService = new google.maps.places.PlacesService(map);
placeService.getDetails({
placeId: placeid
}, function (result, status) {
console.log(result.geometry.location.lat());
console.log(result.geometry.location.lng())
});
}
Change / refactor this sample code according to your need such that you are able set values to latitude and longitude parameters that you are passing to html.
<agm-marker [latitude]="latitude" [longitude]="longitude"></agm-marker>
