使用Google Maps API v3:当鼠标悬停在特定区域时,如何更改鼠标光标？

是的,这可以通过draggableCursor在MapOptions中设置来实现,如下例所示:

<script src="http://maps.google.com/maps/api/js?sensor=false"
type="text/javascript"></script>
</head>
<body>
<div id="map" style="width: 500px; height: 350px"></div>
<script type="text/javascript">
var map = new google.maps.Map(document.getElementById("map"), {
mapTypeId: google.maps.MapTypeId.ROADMAP,
zoom: 8,
center: new google.maps.LatLng(-34.3, 150.6)
});
var ne = new google.maps.LatLng(-34.00, 150.00);
var nw = new google.maps.LatLng(-34.00, 150.50);
var sw = new google.maps.LatLng(-35.00, 150.50);
var se = new google.maps.LatLng(-35.00, 150.00);
var boundingBox = new google.maps.Polyline({
path: [ne, nw, sw, se, ne],
strokeColor: '#FF0000'
});
boundingBox.setMap(map);
google.maps.event.addListener(map, 'mousemove', function(event) {
if ((event.latLng.lat() > se.lat()) && (event.latLng.lat() < ne.lat()) &&
(event.latLng.lng() > ne.lng()) && (event.latLng.lng() < sw.lng())) {
map.setOptions({ draggableCursor: 'crosshair' });
}
else {
map.setOptions({ draggableCursor: 'url(http://maps.google.com/mapfiles/openhand.cur), move' });
}
});
</script>
</body>
</html>
如果运行上面的示例,一旦鼠标在红色矩形内移动,光标将变为十字线.
