'Why is the google maps places search not placing a marker when a location is found in my Angular project?
I am using the @angular/google-maps
package in my Angular project to display a map with a search box for searching locations. When I search for a location, it is displaying the location in the map but it is not highlighting the location with a marker. I have followed all the guidelines provided by google maps documentation. Below is my code.
App.component.html :
<input #search class="form-control" type="text">
<google-map
width="100%"
[center]="currentLocation"
[options]="mapConfigurations"
></google-map>
App.component.ts :
import { Component, ElementRef, OnInit, ViewChild, AfterViewInit } from '@angular/core';
import { GoogleMap } from '@angular/google-maps';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit, AfterViewInit {
@ViewChild('search') searchField!: ElementRef;
@ViewChild(GoogleMap) map: google.maps.Map;
title = 'car-booking-frontend';
currentLocation: any;
mapConfigurations: any;
constructor(){}
ngOnInit(): void {
this.mapConfigurations = {
disableDefaultUI: true,
fullscreenControl: true,
zoomControl: true
};
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition((position)=> {
this.currentLocation = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
});
}
}
ngAfterViewInit() {
const searchBox = new google.maps.places.SearchBox(this.searchField.nativeElement);
this.map?.controls[google.maps.ControlPosition.TOP_CENTER].push(this.searchField.nativeElement);
let markers: google.maps.Marker[] = [];
searchBox.addListener('places_changed', () => {
const places: any = searchBox.getPlaces();
if (places.length === 0) {
return;
}
markers.forEach((marker) => {
marker.setMap(null);
});
markers = [];
const bounds = new google.maps.LatLngBounds();
places.forEach((place: any) => {
if (!place.geometry || !place.geometry.location) {
return;
}
const icon = {
url: place.icon as string,
size: new google.maps.Size(71, 71),
origin: new google.maps.Point(0, 0),
anchor: new google.maps.Point(17, 34),
scaledSize: new google.maps.Size(25, 25),
};
markers.push(
new google.maps.Marker({
map:this.map,
icon:icon,
title: place.name,
position: place.geometry.location,
})
);
if (place.geometry.viewport) {
bounds.union(place.geometry.viewport);
}
else {
bounds.extend(place.geometry.location);
}
});
this.map?.fitBounds(bounds);
});
}
}
App.module.ts :
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>CarBookingFrontend</title>
<base href="/">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="icon" type="image/x-icon" href="favicon.ico">
<script async src="https://maps.googleapis.com/maps/api/js?key={MY_API_KEY}&libraries=places">
</script>
</head>
<body>
<app-root></app-root>
</body>
</html>
While running this, I am able to search for locations, but the locations are not highlighted with markers as shown in google places search box. Instead I am getting an error in the browser console as follows:
InvalidValueError: setMap: not an instance of Map; and not an instance of StreetViewPanorama
Please suggest the required changes.
