问题
I have got a database with latitude and longitude values in it. I can show only one marker at a time. I would like to show multiple markers at the same time. How can I do it?

Here's a very basic example:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
<title>Google Maps Multiple Markers</title>
<script src="http://maps.google.com/maps?file=api&v=2&"
type="text/javascript"></script>
</head>
<body>
<div id="map" style="width: 500px; height: 400px;"></div>
<script type="text/javascript">
var locations = [
['Bondi Beach', -33.890542, 151.274856],
['Coogee Beach', -33.923036, 151.259052],
['Cronulla Beach', -34.028249, 151.157507],
['Manly Beach', -33.800128, 151.282085],
['Maroubra Beach', -33.950198, 151.259302]
];
var map = new GMap2(document.getElementById('map'));
var i;
map.setCenter(new GLatLng(-33.92, 151.25), 10);
for (i = 0; i < locations.length; i++) {
map.addOverlay(
new GMarker(new GLatLng(locations[i][1], locations[i][2]))
);
}
</script>
</body>
</html>
