Hi,
I'm having problems with adding marker clusterer functionality to my map. What I want is to use custom icon for my markers and every marker has its own info window which I want to be able to edit.
I did accomplish that, but now I have problems adding marker clusterer library functionality. I read something about adding markers to array, but I'm not sure what would it exactly mean. Besides, all of the examples with array I have found, don't have info windows and searching through the code I didn't find appropriate way to add them.
Here is my code (mostly from Geocodezip.com):
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript" src="http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/src/markerclusterer.js"></script>
<style type="text/css">
html, body { height: 100%; }
</style>
<script type="text/javascript">
//<![CDATA[
var map = null;
function initialize() {
var myOptions = {
zoom: 8,
center: new google.maps.LatLng(43.907787,-79.359741),
mapTypeControl: true,
mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU},
navigationControl: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
var mcOptions = {gridSize: 50, maxZoom: 15};
var mc = new MarkerClusterer(map, [], mcOptions);
google.maps.event.addListener(map, 'click', function() {
infowindow.close();
});
// Add markers to the map
// Set up three markers with info windows
var point = new google.maps.LatLng(43.65654,-79.90138);
var marker1 = createMarker(point,'Abc');
var point = new google.maps.LatLng(43.91892,-78.89231);
var marker2 = createMarker(point,'Abc');
var point = new google.maps.LatLng(43.82589,-79.10040);
var marker3 = createMarker(point,'Abc');
var markerArray = new Array(marker1, marker2, marker3);
mc.addMarkers(markerArray, true);
}
var infowindow = new google.maps.InfoWindow(
{
size: new google.maps.Size(150,50)
});
function createMarker(latlng, html) {
var image = '/321.png';
var contentString = html;
var marker = new google.maps.Marker({
position: latlng,
map: map,
icon: image,
zIndex: Math.round(latlng.lat()*-100000)<<5
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map,marker);
});
}
