Dear Venky,

you can use like this if any error you get , replay the error.

         $(document).ready(function () {

               $("#ddcity").change(function () {
                   var city = $("#ddcity").val();
                   var geocoder = new google.maps.Geocoder();


                   // Their (  con   ) this varaible where your getting i dont know . your drop down value come above given like that.

                   var com = city + "," + con;

                   geocoder.geocode({ 'address': com }, function (results, status) {
                       if (status == google.maps.GeocoderStatus.OK) {
                           var x = results[0].geometry.location.lat();
                           var y = results[0].geometry.location.lng();
                           var latlng = new google.maps.LatLng(x, y);
                           var myOptions = {
                               zoom: 8,
                               center: latlng,
                               mapTypeId: google.maps.MapTypeId.ROADMAP
                           };
                           map = new google.maps.Map($("#map-canvas").val(), myOptions);
                           var marker = new google.maps.Marker({
                               position: new google.maps.LatLng(x, y),
                               map: map,
                               title: com
                           });

                           var infowindow = new google.maps.InfoWindow({
                               content: com
                           });
                           infowindow.open(map, marker);
                           google.maps.event.addDomListener(window, 'load');
                       } else {
                           res.innerHTML = "Enter correct Details: " + status;
