javascript - Google Maps infoWindow only loading last record on markers

Question

I'm trying to load a google map with dynamic markers and dynamic infoWindows to go with them. Basically I've got the markers working. The infoWindows are clickable and closable, however they do not have the correct content. It seems that the content for every infoWindow is the last record that is found in the query loop. You will see whats happening here Here's the code:

<script type="text/javascript"> 


//Load the Google Map with Options//
  function initialize() {
    var myLatlng = new google.maps.LatLng(42.48019996901214, -90.670166015625);
    var myOptions = {
      zoom: 6,
      center: myLatlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

    //Begin query loop to set the markers and infoWindow content//

    <cfoutput query="GetCoord">
    var LatLng = new google.maps.LatLng(#Client_Lat#, #Client_Lng#);

    var marker = new google.maps.Marker({
        position: LatLng,
        map: map,
        title: "#Client_Company#"
    });   

    var contentString = '<p><b>#Client_Company#</b><br>'+
                        '#Client_Address#<br>'+
                        '#Client_City#,&nbsp; #Client_State# &nbsp; #Client_Zip#<br>'+
                        '<a href="member_detail.cfm?ID=#Client_ID#">View Details</a>';

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

    google.maps.event.addListener(marker, 'click', function() {
        infowindow.open(map,this);

     });
    </cfoutput>
    //End query loop
    }

</script>

Any ideas on why this is happening?

Add content as a property to marker object and use this.content in the event handler:

var marker = new google.maps.Marker(options);
marker.content = '<div>Content goes here....</div>';

var infoWindow = new google.maps.InfoWindow();
google.maps.event.addListener(marker, 'click', function () {
                                infoWindow.setContent(this.content);
                                infoWindow.open(this.getMap(), this);
                            });
