Google Geocoding v3 -获取格式化地址

我想知道是否有人能帮助我。我很难在我的地理编码结果的对话框中获得坐标和格式化的地址，尽管我似乎能够抓取城市，国家。

下面是我正在使用的代码:

http://jsfiddle.net/d5DBh/5/

var myLatlng = new google.maps.LatLng(31.272410, 0.190898);

 // INITALIZATION
 function initialize() {
     var mapOptions = {
         zoom: 4,
         center: myLatlng,
         mapTypeId: google.maps.MapTypeId.ROADMAP
     }
     var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
 }

 // GEOCODE
 function codeAddress() {
     var address = document.getElementById("address").value;
     new google.maps.Geocoder().geocode({
         'address': address
     }, function (results, status) {
         if (status == google.maps.GeocoderStatus.OK) {
             if (results[0]) {
                 var address = "",
                     city = "",
                     town = "",
                     state = "",
                     country = "",
                     location = "",
                     format = "";
                 for (var i = 0; i < results[0].address_components.length; i++) {
                     var addr = results[0].address_components[i];
                     if (addr.types[0] == 'country') country = addr.short_name;
                     else if (addr.types[0] == 'street_address')
                     address = address + addr.long_name;
                     else if (addr.types[0] == 'route')
                     address = address + addr.long_name;
                     else if (addr.types[0] == ['administrative_area_level_1'])
                     state = addr.long_name;
                     else if (addr.types[0] == ['administrative_area_level_2'])
                     town = addr.long_name;
                     else if (addr.types[0] == ['locality'])
                     city = addr.long_name;
                     else if (addr.types[0] == ['location'])
                     location = addr.location;
                 }
                 alert('Formated Address: ' + format + ''n' + 'City: ' + city + ''n' + 'Town: ' + town + ''n' + 'State: ' + state + ''n' + 'Country: ' + country + ''n' + 'Coordinates: ' + location);
             }
     } else {
         alert("Error: We could not find this address - please try and different location");
     };
     });
 }
 initialize();
 document.getElementById("searchItem").onclick = function () {
     codeAddress();
     return false;
 };

另外，因为我是Javascript新手，所以我愿意接受任何关于将其写得更干净的想法。
