首先，前往https://code.google.com/apis/console
點選Service
啟用Google Maps API V3
再到API Access取得Key
將以下程式碼貼入到index.html，記得要更改Key number
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#map_canvas { height: 100% }
</style>
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?key=Your key number&sensor=True or False">
</script>
<script type="text/javascript">
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(-34.397, 150.644),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
mapOptions);
}
</script>
</head>
<body onload="initialize()">
<div id="map_canvas" style="width:100%; height:100%"></div>
</body>
</html>
這個程式主要是以map_canvas這個div來當作Maps
mapOptions設定了地圖的初始值，並且將map_canvas建立成一個新的Map
成果如下：
如果覺得這篇解釋不清楚的話，可以參考『Google Maps JavaScript API 第 3 版』
