在Google地图中获取具有经度和纬度的地址和邮政编码

Question

in google map api, i want to extract map center latitude and longitude and get address of there like a zipcode. this is possible to get zipcode ?
i use this for this purpose

var lat = -24.448674;
        var lng = 135.684569;
        var geocoder = new google.maps.Geocoder();
        var latlng = new google.maps.LatLng(lat, lng);
        geocoder.geocode({'latLng': latlng}, function(results, status)
        {
            if (status == google.maps.GeocoderStatus.OK)
            {
                if (results[1]) {
                    alert(results[1].formatted_address);
                } else {
                    alert("No results found");
                }
            }
            else
            {
                alert("Geocoder failed due to: " + status);
            }
        });

but in above code i can't get zipcode and get postal code!

You can get postal code searching for postal_code type:

    if (status == google.maps.GeocoderStatus.OK) {
        if (results[0]) {
            for (var i = 0; i < results[0].address_components.length; i++) {
                var types = results[0].address_components[i].types;

                for (var typeIdx = 0; typeIdx < types.length; typeIdx++) {
                    if (types[typeIdx] == 'postal_code') {
                        //console.log(results[0].address_components[i].long_name);
                        console.log(results[0].address_components[i].short_name);
                    }
                }
            }
        } else {
            console.log("No results found");
        }
    }

As far as I'm aware, you've answered your own question here. The 'Postal Code' is the generic name given to the mailing address identifier used in each country. In the case of the US this would be the 'Zip Code', in the UK the 'Post Code' etc.

From the documentation you linked:

postal_code indicates a postal code as used to address postal mail within the country.

The field under Postal Code is likely what you're looking for, don't let the naming convention fool you. It would be unnecessary work on the part of Google to rename the field for each country's possible variations.
