Question

Having similar problem as others have had on this website where it shows only the last marker’s info window info in all markers. Can’t seem to solve this with any of the solutions given. Also, the last one of my markers doesn’t show an info window at all.

<script src="http://www.google.com/jsapi"></script>
<script type="text/javascript" src="data2.json"></script>
<script type="text/javascript" src="js/markerclusterer.js"></script>

<script type="text/javascript">
  google.load('maps', '3', {
    other_params: 'sensor=false'
  });
  google.setOnLoadCallback(initialize);

  function initialize() {

var center = new google.maps.LatLng(55.4419, -4.1419);

var map = new google.maps.Map(document.getElementById('map'), {
      zoom: 5,
      center: center,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    });


var markers = [];
for (var i = 0, dataPhoto; dataPhoto = data.markers[i]; i++) {
      var latLng = new google.maps.LatLng(dataPhoto.latitude,dataPhoto.longitude);
      var theTitle = dataPhoto.address;
      var contentString = '<div align="left"><img src="logo.gif" alt="" width="242" height="71" /><br /><br /><p style="color:#000000;">' + data.markers[i].address + '<br />' + dataPhoto.telephone + '</p></div>';



      var infowindow = new google.maps.InfoWindow({
        content: contentString,
        });



    var thisIcon = 'markers/image.png';


                for (var i = 0, marker; marker = markers[i]; i++) {google.maps.event.addListener(marker, 'click', function() {infowindow.open(map,this);});
      } 


      var marker = new google.maps.Marker({
        position: latLng,
        clickable: true,
        title: theTitle,
        icon: thisIcon,
      });

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


  }


</script>

Any help much appreciated!
