I have create a marker using advancedMarkerView
const centerMarkerE = document.createElement("div");
let centerMarkerHtml = "<div class='center_marker'><img src='/images/front/pin.png' /></div>";
centerMarkerE.innerHTML = centerMarkerHtml;
centerMarker = new google.maps.marker.AdvancedMarkerView({
map,
position: initialLocation,
content: centerMarkerE,
});
For normal marker I can use setPosition(initialLocation) but it not work for AdvancedMarkerView
How can I change the position of advance marker ?

Reset to default 13Use Dot Notation instead of a setter method
AdvancedMarkerElementOptions interface have a position property. The documentation describes it this way:
Sets the AdvancedMarkerElement's position. An AdvancedMarkerElement may be constructed without a position, but will not be displayed until its position is provided - for example, by a user's actions or choices. An AdvancedMarkerElement's position can be provided by setting AdvancedMarkerElement.position if not provided at the construction.
So if you are instantiating an advanced marker like this:
const marker = new AdvancedMarkerElement({
map,
position: { lat: 14.535455012359806, lng: 120.98195420962453 },
});
You can change position within a click event listener like this:
btn.addEventListener("click", function(){
// This is how to change marker location
marker.position = {lat: 14.53546539778815, lng: 120.98422872277972}
});
And this should work as expected.
Here's a sample snippet that you can play around with and check:
async function initMap() {
// Request needed libraries.
const btn = document.getElementById("change-location-btn");
const { Map } = await google.maps.importLibrary("maps");
const { AdvancedMarkerElement } = await google.maps.importLibrary("marker");
const map = new Map(document.getElementById("map"), {
center: { lat: 14.535455012359806, lng: 120.98195420962453 },
zoom: 16,
mapId: "4504f8b37365c3d0",
});
const marker = new AdvancedMarkerElement({
map,
position: { lat: 14.535455012359806, lng: 120.98195420962453 },
});
// button to change location
btn.addEventListener("click", function(){
// map.setCenter({lat: 14.53546539778815, lng: 120.98422872277972})
// This is how to change marker location
marker.position = {lat: 14.53546539778815, lng: 120.98422872277972}
});
}
initMap();
/*

* that contains the map.
*/
#map {
height: 100%;
}
/*
* Optional: Makes the sample page fill the window.
*/

height: 100%;
margin: 0;
padding: 0;

I came across this question as I was having issues updating a current marker's location using @googlemaps/react-wrapper.
@yrll's answer pointed me in the right direction, however, it is not enough to update the location. Updating the location every time the click was triggered would append a new Marker to the map.
To get it to work as expected, I had to change how I defined the AdvancedMarkerElement. I do not pass the map object to the constructor.
useEffect(() => {
const pinBackground = new google.maps.marker.PinElement({
background: "#FBBC04",
});
const marker = new google.maps.marker.AdvancedMarkerElement({
content: pinBackground.element,
});
setMarker(marker);
}, []);
Instead, I pass in the map to the marker on the first change. Then it works as expected.
const updateMarker = useCallback(
(location: google.maps.LatLng) => {
if (marker) {
if (!marker.map) {
marker.map = map;
}
if (marker.position !== location) marker.position = location;
}
},
[map, marker]
);
