啟用 Google Maps JavaScript API

為協助您開始,我們將先引導您使用「Google 開發人員控制台」來執行一些動作:

  1. 建立或選擇專案
  2. 啟用 Google Maps JavaScript API 與相關服務
  3. 建立適當的金鑰

Region code biasing (US)

This demonstrates sending a geocoding request for "Toledo" and receiving a result in the US. The result returned depends on the region of the map. See also the demo for the Spanish region code.

Read the documentation or view this example full screen.

function initMap() {
  var map = new google.maps.Map(document.getElementById('map'), {zoom: 8});
  var geocoder = new google.maps.Geocoder;
  geocoder.geocode({'address': 'Toledo'}, function(results, status) {
    if (status === 'OK') {
      map.setCenter(results[0].geometry.location);
      new google.maps.Marker({
        map: map,
        position: results[0].geometry.location
      });
    } else {
      window.alert('Geocode was not successful for the following reason: ' +
          status);
    }
  });
}
<div id="map"></div>
/* 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;
}
 <!-- Replace the value of the key parameter with your own API key. -->
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCkUOdZ5y7hMm0yrcCQoCvLwzdM6M8s5qk&callback=initMap">
