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

Synchronous Loading

Read the documentation or view this example full screen.

In this example, the Maps API is loaded synchronously. We omitted the async attribute from the script tag that loads the API, and we also omitted the callback parameter.

When the API is loaded synchronously, subsequent script tags will not execute until the API is fully loaded. Because of this, the final script tag can call new google.maps.Map and assume that google.maps.Map has been defined.

var map = new google.maps.Map(document.getElementById('map'), {
  center: {lat: -34.397, lng: 150.644},
  zoom: 8
});
<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 src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCkUOdZ5y7hMm0yrcCQoCvLwzdM6M8s5qk"></script>
