Google Maps V.3 Multiple Markers With Infowindow How To

Written by  Caleb Nance

Today I want to show you how to set multiple markers in Google Maps V.3 with each marker having their own infowindow.

<html>
<head>
<style>
body { font-family: Helvetica; } .map-content h3 { margin: 0; padding: 5px 0 0 0; }
</style>
<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=true"></script>
<script>
// Set the Map variable
var map;
function initialize() {
var myOptions = {
zoom: 9,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var all = [
["Location 1", "Summerdale Rd", "Elon", "NC", "27253", "36.150491", "-79.5470544"],
["Location 2", "7205 Olmstead Dr", "Burlington", "NC", "27215", "36.069974", "-79.548101"],
["Location 3", "W Market St", "Graham", "NC", "27253", "36.0722225", "-79.4016207"],
["Location 4", "Mt Hermon Rock Creek Rd", "Graham", "NC", "27253", "35.9826328", "-79.4165216"],
["Location 5", "415 Spring Garden St", "Greensboro", "NC", "27401", "36.06761", "-79.794984"]
];
var infoWindow = new google.maps.InfoWindow;
map = new google.maps.Map(document.getElementById('map_canvas'), myOptions);
// Set the center of the map
var pos = new google.maps.LatLng(36.0621881, -79.5101063);
map.setCenter(pos);
function infoCallback(infowindow, marker) {
return function() {
infowindow.open(map, marker);
};
}
function setMarkers(map, all) {
for (var i in all) {
var name = all[i][0];
var address = all[i][1];
var city = all[i][2];
var state = all[i][3];
var zip = all[i][4];
var lat = all[i][5];
var lng = all[i][6];
var latlngset;
latlngset = new google.maps.LatLng(lat, lng);
var marker = new google.maps.Marker({
map: map, title: city, position: latlngset
});
var content = '<div class="map-content"><h3>' + name + '</h3>' + address + '<br />' + city + ', ' + state + ' ' + zip + '<br /><a href="http://maps.google.com/?daddr=' + address + ' ' + city + ', ' + state + ' ' + zip + '" target="_blank">Get Directions</a></div>';
var infowindow = new google.maps.InfoWindow();
infowindow.setContent(content);
google.maps.event.addListener(
marker,
'click',
infoCallback(infowindow, marker)
);
}
}
// Set all markers in the all variable
setMarkers(map, all);
};
// Initializes the Google Map
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map_canvas" style="height: 500px; width: 800px;"></div>
</body>
</html>
