add marker to the google maps in angular component

I am trying to add marker to the google maps.
but I am facing below error.
InvalidValueError: setMap: not an instance of Map; and not an instance of StreetViewPanorama
can you tell me how to fix it.
providing code and stackblitz below.
https://stackblitz.com/edit/angular-gmaps-api-suvdaf?file=src/app/map-loader.ts
return MapLoader.load().then((gapi) => {
this.map = new google.maps.Map(gmapElement.nativeElement, {
center: new google.maps.LatLng(lat, lng),
zoom: zoom,
mapTypeId: type,
// label: "A"
});
this.map1 = new google.maps.Marker({
label: "A",
position: { lat: 59.33555, lng: 18.029851 },
map: map,
title: 'Hello World!'
});
// let markerSimple = new google.maps.Marker({
// label: "A",
// position: { lat: 59.33555, lng: 18.029851 },
// map: map,
// title: 'Hello World!'
// });
});

If i have understand your question this modified code will add markers

Draw Polyline between markers Ionic Google Maps JavaScript

Hi guys this is my first post in this site, im working in a App in Ionic that shows your position with a marker when you push a button, you can push it again to update your position and add a Marker on that position, i want to draw a Polyline between this markers but i havent succeed yet. i know there are some ways to draw polylines my idea is to extract the lat, long coordinates of the marker, save them in a array and then set that as a "path" to draw the Polyline but im having problems with the creation of the array like in the comment below. here is my code:
import { Component, ViewChild, ElementRef } from '#angular/core';
import { NavController} from 'ionic-angular';
import { Geolocation } from '#ionic-native/geolocation';
declare var google;
#Component({
selector: 'home-page',
templateUrl: 'home.html'
})
export class HomePage {
#ViewChild('map') mapElement: ElementRef;
map: any;
me: any;
markers=[];
lat=[];
long=[];
constructor(public navCtrl: NavController, public geolocation: Geolocation) {
}
ionViewDidLoad(){
this.loadMap();
}
loadMap() {
this.geolocation.getCurrentPosition().then((position) => {
let mylatLng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
let mapOptions = {
center: mylatLng,
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
this.map = new google.maps.Map(this.mapElement.nativeElement, mapOptions);
},
(err) => {
console.log(err);
});
}
addMarker(){
let marker = new google.maps.Marker({
map: this.map,
animation: google.maps.Animation.DROP,
});
let content = '<p>Posición: ' + marker.setPosition() + '</p>'
if (navigator.geolocation) navigator.geolocation.getCurrentPosition(function(pos) {
var me = new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude);
marker.setPosition(me);
},
function(error) {
// ...
});
this.markers.push(marker);
this.addInfoWindow(marker, content);
}
addInfoWindow(marker, content){
let infoWindow = new google.maps.InfoWindow({
content: content
});
if (navigator.geolocation) navigator.geolocation.getCurrentPosition(function(pos) {
var me = new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude);
infoWindow.setContent('<p>Posición: ' + me + '</p>')
},
function(error) {
// ...
});
google.maps.event.addListener(marker, 'click', () => {
infoWindow.open(this.map, marker);
});
}
setMapAll(map) {
for (var i = 0; i < this.markers.length; i++) {
this.markers[i].setMap(map);
}
}
clearMarkers() {
this.setMapAll(null);
}
deleteMarkers() {
this.clearMarkers();
this.markers = [];
}
// Im having problems here
addPolyLine() {
var poly = new Array();
for (var j=0; j<this.lat.length;j++){
var pos= new google.maps.LatLng(this.lat[j],this.long[j])
poly.push(pos);
}
var flightPath = new google.maps.Polyline({
path: poly,
geodesic: true,
strokeColor: '#FF0000',
strokeOpacity: 1.0,
strokeWeight: 2
});
flightPath.setMap(this.map);
}
}
And the HTML page:
<ion-header>
<ion-navbar>
<ion-title>
MapaPrueba
</ion-title>
<ion-buttons end>
<button ion-button (click)="addMarker()"><ion-icon name="add"></ion-icon>Agregar Pos</button>
</ion-buttons>
</ion-navbar>
</ion-header>
<ion-content>
<div #map id="map"></div>
<ion-fab left bottom>
<button ion-fab color="light" (click)="clearMarkers()">
<ion-icon name="eye-off"></ion-icon>
</button>
</ion-fab>
</ion-content>

There is a full example of that in the official documentation and here below as well.
In short you have to:
Create a Polyline and set it on the map (one time)
Get the Polyline path with the Polyline getPath() method
Push your new
coordinates to the path
var map;
var polyLine;
var polyOptions;
function initialize() {
var mapOptions = {
zoom: 5,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: new google.maps.LatLng(0,0)
};
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
polyOptions = {
strokeColor: '#0026b3',
strokeOpacity: 1.0,
strokeWeight: 1,
geodesic: true,
}
polyLine = new google.maps.Polyline(polyOptions);
polyLine.setMap(map);
google.maps.event.addListener(map, 'click', function(event) {
addPoint(event);
});
}
function addPoint(event) {
var path = polyLine.getPath();
path.push(event.latLng);
var marker = new google.maps.Marker({
position: event.latLng,
map: map,
});
map.setCenter(event.latLng);
}
initialize();
#map-canvas {
height: 200px;
}
<div id="map-canvas"></div>

add custom icons to google maps nearby places part2

got my current location with nearby places eg.(grocery_or_supermarket) and their icons.
but what i want to do is give each of the shops their own logo as an icon.
I'm new to JS so any help plz!
I have code to share if needed.
<script>
var infowindow,
placemarkers = [];
var iconBase = 'https://maps.google.com/mapfiles/kml/shapes/';
var icons = {
parking: {
icon: iconBase + 'parking_lot_maps.png'
},
library: {
icon: iconBase + 'library_maps.png'
},
info: {
icon: iconBase + 'info-i_maps.png'
},
grocery_or_supermarket: {
icon: iconBase + 'convenience.png'
}
};
function placeSearch(map, request) {
var map = map;
var service = new google.maps.places.PlacesService(map);
service.search(request,
function (results, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
var bounds = new google.maps.LatLngBounds();
for (var i = 0; i < results.length; ++i) {
bounds.extend(results[i].geometry.location);
placemarkers.push(createMarker(results[i].geometry.location,
map,
icons['grocery_or_supermarket'].icon,
results[i].name,
false, {
fnc: function () {
infowindow.open();
}
}));
}
map.fitBounds(bounds);
}
});
}
function createMarker(latlng, map, icon, content, center, action) {
var marker = new google.maps.Marker({
map: map,
animation: google.maps.Animation.DROP,
position: latlng,
content: content
});
////////toggle bounce////
google.maps.event.addListener(marker, 'click', toggleBounce);
function toggleBounce() {
if (marker.getAnimation() != null) {
marker.setAnimation(null);
} else {
marker.setAnimation(google.maps.Animation.BOUNCE); } } ///////bounce end////
if (icon) {
marker.setIcon(icon);
}
if (center) {
map.setCenter(latlng);
}
google.maps.event.addListener(marker, 'click', function () {
infowindow.setContent(this.content);
infowindow.open(map, this);
});
if (action) {
action.fnc(map, action.args);
}
return marker;
}
function initialize() {
var location = new google.maps.LatLng(-33.8665433, 151.1956316),
map = new google.maps.Map(document.getElementById('map'), {
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: location,
zoom: 15,
});
infowindow = new google.maps.InfoWindow();
navigator.geolocation.getCurrentPosition(function (place) {
createMarker(
new google.maps.LatLng(place.coords.latitude,
place.coords.longitude),
map,
null,
'your current position',
true, {
fnc: placeSearch,
args: {
radius: 5000,
types: ['grocery_or_supermarket'],
location: new google.maps.LatLng(place.coords.latitude,
place.coords.longitude)
}
});
});
}
</script>

You can easily do with not so much code:
var iconBase = 'http://www.yourwebsite.com/';
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
icon: iconBase + 'myMarker.png' // Set yourt marker here
});

Infowindow showing same street view for multiple markers?

Infowindow showing street view but multiple markers showing same street view.
Its taking last address to show street view in all markers.
Code:
geocoder.geocode( { 'address': "{!acc.BillingCity}"}, function(results, status) {
alert("{!acc.BillingCity}");
if (status == google.maps.GeocoderStatus.OK) {
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location,
title : 'Click Here!!!'
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map, marker);
});
var pano = null;
google.maps.event.addListener(infowindow, 'domready', function() {
if (pano != null) {
pano.unbind("position");
pano.setVisible(false);
}
pano = new google.maps.StreetViewPanorama(document.getElementById("content"), {
navigationControl: true,
navigationControlOptions: {
style: google.maps.NavigationControlStyle.ANDROID
},
enableCloseButton: false,
addressControl: false,
linksControl: false
});
pano.bindTo("position", marker);
pano.setVisible(true);
});
google.maps.event.addListener(infowindow, 'closeclick', function() {
pano.unbind("position");
pano.setVisible(false);
pano = null;
});
markerBounds.extend(results[0].geometry.location);
map.fitBounds(markerBounds);
}else if(status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
wait = true;
setTimeout("wait = true", 2000);
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
How to deal with (StreetViewPanorama) to show street view with multiple markers.

Detect the user current location,add a marker onto that position in Sencha Touch V2

The code below facilitates a map to be displayed with markers added onto it from data in a JSON file.The getDirections from one marker to another has also been facilitated.
Need to:Detect the user current location,add a marker onto that position and apply that location to the start variable given within the code below so that directions from that current position to the marker that has been tapped can be plotted.
