I m developing a map that will cluster pins to prevent over crowded pin, but I wanted to create an infoWindow that will list all the marker when I click on the marker, I tried to get some help around and found out i can do it using marker.getTitle() but this is not helping me because I m using makrewithLable object and not using title, my question is there any why to add title to the marker or as I prefer to use the label instead to list them in the infowindow. here is a copy of my work.
google.setOnLoadCallback(initialize);
var globalMarker = [];
var map;
function initialize() {
var center = new google.maps.LatLng(45.4214, -75.6919);
map = new google.maps.Map(document.getElementById('map'), {
zoom: 3,
center: center,
disableDoubleClickZoom: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var markers = [];
var infowindow = new google.maps.InfoWindow();
for(i=0; i<50; i++) {
var latLng = new google.maps.LatLng(center.lat() + Math.random() - 0.5, center.lng() + Math.random() - 0.5);
//var latLng = new google.maps.LatLng(45.4214, -75.6919)
markers[i] = new MarkerWithLabel({
position: latLng,
draggable: true,
raiseOnDrag: true,
map: map,
labelContent: "Marker ID = "+i,
labelAnchor: new google.maps.Point(30, 0),
labelClass: "labels", // the CSS class for the label
labelStyle: {opacity: 0.75}
});
markers.push(markers);
makeDiv(i, 15, "Marker #");
google.maps.event.addListener(markers[i], 'click', function(e) {
infowindow.setContent('Marker postion: ' + this.getPosition());
infowindow.open(map, this);});
}
var clusterOptions = { zoomOnClick: false }
var markerCluster = new MarkerClusterer(map, markers, clusterOptions);
globalMarker = markers.slice();
google.maps.event.addListener(markerCluster, 'clusterclick', function(cluster) {
var content = '';
// Convert lat/long from cluster object to a usable MVCObject
var info = new google.maps.MVCObject;
info.set('position', cluster.center_);
//----
//Get markers
var markers = cluster.getMarkers();
var titles = "";
//Get all the titles
for(var i = 0; i < markers.length; i++) {
titles += markers[i].getTitle() + "\n";
}
//----
infowindow.close();
infowindow.setContent(titles); //set infowindow content to titles
infowindow.open(map, info);
});
}
function makeDiv(index, zoomLevel, content) {
document.getElementById("sidebar").innerHTML += '<div onclick="zoomIn(' + index + ',' + zoomLevel + ')">' + content + ' ' + index + '</div>';
}
function zoomIn(index, zoomLevel) {
map.setCenter(globalMarker[index].getPosition());
map.setZoom(zoomLevel);
}
google.maps.event.addDomListener(window, 'load', initialize);
Thank you

The key change was titles += markers[i].labelContent + "\n";. (You can use the dot notation or markers[i]["labelContent"] to refer back to any property you set). I also changed the part markers.push(markers), and that when zoom is changed the window disappears (because cluster number is likely to change) Everything else looked great!
