Geocoding Service

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

function initMap() {
  const map = new google.maps.Map(document.getElementById("map"), {
    zoom: 8,
    center: { lat: -34.397, lng: 150.644 },
  });
  const geocoder = new google.maps.Geocoder();
  document.getElementById("submit").addEventListener("click", () => {
    geocodeAddress(geocoder, map);
  });
}

function geocodeAddress(geocoder, resultsMap) {
  const address = document.getElementById("address").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);
    }
  });
}

CSS

/* Always set the map height explicitly to define the size of the div
       * element that contains the map. */
#map {
  height: 100%;
}

/* Optional: Makes the sample page fill the window. */
html,
body {
  height: 100%;
  margin: 0;
  padding: 0;
}

#floating-panel {
  position: absolute;
  top: 10px;
  left: 25%;
  z-index: 5;
  background-color: #fff;
  padding: 5px;
  border: 1px solid #999;
  text-align: center;
  font-family: "Roboto", "sans-serif";
  line-height: 30px;
  padding-left: 10px;
