Many InfoWindow Tokens in Google Maps v3

Question

I am testing this for about 1 hour. But for some reason, I can't get it to work to display different text for each marker. By clicking on each of them, a new window will open (the old one will be closed, which is good), but the text inside the window is always the text that I set in the last marker:

function initialize() {
    var center = new google.maps.LatLng(51.133333,10.416667);
    var map = new google.maps.Map(document.getElementById('map'), {
      zoom: 6,
      center: center,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    });
    var markers = [];

    for (var i = 0, dataPhoto; dataPhoto = data.photos[i]; i++) {
      var latLng = new google.maps.LatLng(dataPhoto.latitude,
                   dataPhoto.longitude);
      var marker = new google.maps.Marker({
        position: latLng,
        title: dataPhoto.infotitle,
        map: map,
      });

      /* Create Info Windows */         

      var infowindow = new google.maps.InfoWindow({
        content: " "
      });
      google.maps.event.addListener(marker, 'click', function() {
        infowindow.setContent('<h3>'+marker.title+'</h3>'+' Infotext');
        infowindow.open(map, this);
      });
      markers.push(marker);
    }
    var markerCluster = new MarkerClusterer(map, markers);
} 

I saw some solutions here, but none of them seemed to work properly for me. I am very grateful for your help!

Answer 1

You just need to set Content to this.title, not marker.title

infowindow.setContent('<h3>'+this.title+'</h3>'+' Infotext');

Change your code to

var markers = new Array();
var infowindow = new Array();
var map;
function initialize() {
    var center = new google.maps.LatLng(51.133333,10.416667);
    map = new google.maps.Map(document.getElementById('map'), {
      zoom: 6,
      center: center,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    });

    for (var i = 0, dataPhoto; dataPhoto = data.photos[i]; i++) {
      var latLng = new google.maps.LatLng(dataPhoto.latitude,
                   dataPhoto.longitude);
     markers[i] = new google.maps.Marker({
        position: latLng,
        title: dataPhoto.infotitle,
        map: map,
      });
      /* Create Info Windows */         

      infowindow[i] = new google.maps.InfoWindow({
        content: " "
      });
      google.maps.event.addListener(markers[i], 'click', function() {
        infowindow[i].setContent('<h3>'+this.title+'</h3>'+' Infotext');
        infowindow[i].open(map, this);
      });

    }
    var markerCluster = new MarkerClusterer(map, markers);
}
