Question

I’m trying to extract some extra information from a location using google map api. I take a look and it’s possible but I don’t understand well where I’ve to put the bounds parameter. This is my 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 was not successful for the following reason: " + status);
    }
});

I suppose to add the bound after ‘address’:address but not clear how. I tryied with that but it doesn’t works:

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

I don’t know if have familiar with Italian province but I need something like 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 I 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 to print using alert(results[0].address_components); it doesn’t show me anything, how can I extract this:

           "long_name" : "Venezia",
           "short_name" : "VE",
           "types" : [ "administrative_area_level_2", "political" ]

thanks,
Andrea

Answer 1

I do not see any other solution than iterate by address_components and match first data with short_name that contains 2 letters.

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