javascript - extract province from location using google api -

i'm trying extract information location using google map api. take , it's possible don't understand i've put bounds parameter. request:

var address = document.getelementbyid("address").value;     geocoder.geocode( { 'address': address}, function(results, status) {     if (status == google.maps.geocoderstatus.ok) {         alert(results[0].formatted_address);         } else {         alert("geocode not successful following reason: " + status);     } }); 

i suppose add bound after 'address':address not clear how. tryied doesn't works:

geocoder.geocode( { 'address': address, "types":["sublocality","political"]}, function(results, status) { 

i don't know if have familiar italian province need that:

request: venezia
response: ve or venezia

request: murano
response: ve or venezia

---- improved:

using http://maps.googleapis.com/maps/api/geocode/json?address=murano&sensor=false can obtain this:

{    "results" : [       {          "address_components" : [             {                "long_name" : "murano",                "short_name" : "murano",                "types" : [ "natural_feature" ]             },             {                "long_name" : "venezia",                "short_name" : "venezia",                "types" : [ "locality", "political" ]             },             {                "long_name" : "venezia",                "short_name" : "ve",                "types" : [ "administrative_area_level_2", "political" ]             },             {                "long_name" : "veneto",                "short_name" : "veneto",                "types" : [ "administrative_area_level_1", "political" ]             },             {                "long_name" : "italia",                "short_name" : "it",                "types" : [ "country", "political" ]             },             {                "long_name" : "30141",                "short_name" : "30141",                "types" : [ "postal_code" ]             }          ], 

trying print using alert(results[0].address_components); doesn't show me anything, how can extract this:

           "long_name" : "venezia",            "short_name" : "ve",            "types" : [ "administrative_area_level_2", "political" ] 

thanks, andrea

i not see other solution iterate address_components , match first data short_name contains 2 letters.

var len = results[0].address_components.length; var data; ( var = 0; < len; i++ ) {     if ( results[0].address_components[i].short_name.length == 2 ) {         data = results[0].address_components[i];         break;     } }
