show title of marker in infobox on google map

Question

I want to show the title (place name) of each place where there is a marker on the google map. At the moment is is showing the co-ordinates

infowindow.setContent("coord:"+dmarker.getPosition().toUrlValue(6));

but I want it to show the "title" of the place. How do I do this My code is:

    <script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
   <script type="text/javascript">
   var map = null;
var infowindow = new google.maps.InfoWindow();
var bounds = new google.maps.LatLngBounds();
   var markers = [
                        { 
                             "title": <?php echo "'" . $info['name']  . "'"; ?>,
                             "lat": <?php echo "'" . $info['lat'] . "'"; ?>,
                             "lng": <?php echo "'" . $info['long'] . "'"; ?>,
                        },


            {
               "title": 'Kinar Hotel',
               "lat": '32.8617740',
               "lng": '35.6452770',

Answer 1

Use the title as marker-property and access this property in the click-handler:

var dmarker = new google.maps.Marker({position:des, 
                                      map:map,
                                      title:markers[i+1].title
                                     });

google.maps.event.addListener(dmarker, "click", function(evt) {  
    infowindow.setContent(this.get('title'));
    infowindow.open(map,this);
});
