I need to create info-window out of this code, I'm lacking of application logic and totally new to programming i use this open-source code
This code add users to the map along with their marker
    function loadMarkers(data) {
    for(key in data) {
        var user = data[key];
        xmartlabschat.addUser(user);
        markers[key] = getMarker(user.lat, user.lng, user.name);
    }
}
I tried to use the basic code for info-window
var infoWindow = new google.maps.InfoWindow(user.name);
markers[key].addListener('click', function(){
        infoWindowMe.open(map,markers[key);
However this code turns all marker into same name with the user instead of different names since im clicking other users marker
Please Help Here the screenshot I took
