Question

I have a simple Google map v3 code. It creates the map and adds a marker to the markerCluster. It is all working fine, except for setting content to the infoWindow and opening it.
The function getSupplierDetails() simply returns a short string (i.e. “Red Supply”).

Here is the problem: If I hard code the text “Red Supply” to the setContent line like infoWindow.setContent("Red Supply"); then the infowindow open fine with the content.

But if I leave it as it is as in the code below the infowindow does not open at all, although the getSupplierDetails() function returns “Red Supply”.

getSupplierDetails() function returns this JSON string: {"popupContent": "Red Suppplier"} from Firebug.

Spent so long on it without any solution. Any help appreciated.

Thanks

var map;
var markerCluster;
var infoWindow;

$(document).ready(function() {

  if (mapElem != null) {
        var latlng = new google.maps.LatLng(54.664936, -2.706299);
        var myOptions = {
            zoom: 5,
            center: latlng,
            mapTypeId: google.maps.MapTypeId.ROADMAP,
        };

        map = new google.maps.Map(mapElem, myOptions);
        markerCluster = new MarkerClusterer(map);
        infoWindow = new google.maps.InfoWindow();

    AddMarkers();
  }
});

function AddMarkers(){
    markerCluster.clearMarkers();
    var marker = new google.maps.marker({position:latLng, map:map, title:"title"});

    google.maps.event.addListener(marker, 'click', function() {
      var res = getSupplierDetails();
      infoWindow.setContent(res);
      infoWindow.open(map, this);
    });

    markers.push(marker);
    markerCluster.addMarkers(markers);
}


function getSupplierDetails() { //returns {"popupContent": "Red Suppplier"}
    $.ajax({
        type: 'POST',
        url: "sitedetail.aspx",
        dataType: 'json',
        timeout: 30000,
        success: function(data) {
            return data.popupContent;
        },
        error: function(xhr, textStatus, thrownError) {
            var resp = JSON.parse(xhr.responseText);
            alert(resp.message);

        }
    });
}

function getSupplierDetails() { // returns "Red Suppplier" or ""
    var content = '';
    $.ajax({
        type: 'POST',
        url: "sitedetail.aspx",
        dataType: 'json',
        timeout: 30000,
        success: function(data) {
            content = data.popupContent;
        },
        error: function(xhr, textStatus, thrownError) {
            var resp = JSON.parse(xhr.responseText);
            alert(resp.message);

        }
    });
    return content;
}
