HTML的代码该这样写：
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script src="http://maps.google.com/maps?file=api&v=1&key=
[YOURKEY]" type="text/javascript"></script>
</head>
<body>
<!-- 为了显示下面的div语句，特意把div改为div_v -->
<div_v id="map" style="width: 500px; height: 400px"></div_v>
<script type="text/javascript">
//<![CDATA[
var map = new GMap(document.getElementById("map"));
map.addControl(new GSmallMapControl());
map.centerAndZoom(new GPoint(-122.1419, 37.4419), 4);
//]]>
</script>
</body>
</html>
如果要在地图上标注某一地点，使用如下的 JavaScript:
map.addOverlay(new GMarker(new GPoint(-122.499447, 45.484206)));
