This example creates a map along with a text input field and a button. When you click the "geocode" button, the sample sends a geocoding request, then pans the map to the geocoded location.
Read the documentation.
TypeScript
function initMap(): void {
const map = new google.maps.Map(
document.getElementById("map") as HTMLElement,
{
zoom: 8,
center: { lat: -34.397, lng: 150.644 }
}
);
const geocoder = new google.maps.Geocoder();
(document.getElementById("submit") as HTMLButtonElement).addEventListener(
"click",
() => {
geocodeAddress(geocoder, map);
}
);
}
function geocodeAddress(
geocoder: google.maps.Geocoder,
resultsMap: google.maps.Map
) {
const address = (document.getElementById("address") as HTMLInputElement)
.value;
geocoder.geocode({ address: address }, (results, status) => {
if (status === "OK") {
resultsMap.setCenter(results[0].geometry.location);
new google.maps.Marker({
map: resultsMap,
position: results[0].geometry.location
});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
JavaScript

center: { lat: -34.397, lng: 150.644 }
});
const geocoder = new google.maps.Geocoder();

new google.maps.Marker({
map: resultsMap,
position: results[0].geometry.location
