我注意到在大多数谷歌地图中,您无法将标记图标拖到地址栏中并查看或下载图标.png文件本身。而不是将光标悬停在标记上,您可以看到javascript:void(0)。
这是如何实现的?谢谢!

看起来v3 API中的标记无法拖动到地址栏,v2 API中的标记可以。
以下v3示例不允许标记移动(在Firefox和Chrome中测试)。它还会在状态栏中显示javascript:void(0)
:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/>
<title>Google Maps API No Marker Dragging v3</title>
<script src="http://maps.google.com/maps/api/js?sensor=false"
type="text/javascript"></script>
</head>
<body>
<div id="map" style="width: 500px; height: 400px;"></div>
<script type="text/javascript">
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 2,
center: new google.maps.LatLng(35.00, -25.00),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
new google.maps.Marker({
position: map.getCenter(),
map: map
});
</script>
</body>
</html>

另一方面,使用v2 API的相同示例允许将标记拖动到地址栏:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/>
<title>Google Maps API No Marker Dragging v2</title>
<script src="http://maps.google.com/maps?file=api&v=2&sensor=false"
type="text/javascript"></script>
</head>
<body onunload="GUnload()">
<div id="map" style="width: 500px; height: 400px;"></div>
<script type="text/javascript">
var map = new GMap2(document.getElementById("map"));
map.setCenter(new GLatLng(35.00, -25.00), 2);
map.addOverlay(new GMarker(map.getCenter()));
</script>
</body>
</html>
