Googlemaps 反向地理编码获取国家/地区名称、英国国家/地区
我正在使用谷歌地图 Api V3 并使用反向地理编码来查找点击的国家/地区的名称。 这似乎对除英国境内的国家/地区之外的大多数国家/地区都适用。
英国由英格兰、苏格兰、威尔士和北爱尔兰组成，这是 4 个独立的国家，但谷歌地图（以及大多数其他国家的地图）将它们全部视为“英国”。
我需要知道英国境内的哪个特定国家/地区被点击，而不仅仅是英国被点击！
我正在使用以下 javascript，目前仅使用 Visual Studios“观看”功能来深入研究“结果[1]”以查看其中包含的内容。
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(51.8052184317649, -4.965819906250006);
var myOptions = {
zoom: 5,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
google.maps.event.addListener(map, 'click', function (event) {
if (confirm('Is this the location you would like to you for your company?')) {
geocoder.geocode({ 'latLng': event.latLng }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (results[1]) {
}
}
});
}
});
}
如果我在地图缩放得很远时单击，国家名称（即威尔士）会返回类型“administrative_area_level_1”和“political”，但是当您放大时，它不再存在，因为它只给出不包含“的地址”威尔士”。
有谁知道我如何解决这个问题？我相信其他英国人也遇到过这个吗？
I am using google maps Api V3 and using reverse geocoding to find the name of a country clicked on.
This appears to work fine for most countries except the countries within the UK.
The UK consists of England, Scotland, Wales and Northern Ireland, which are 4 separate countries, but google maps (and most other country things) see them all as just "UK".
I need to know which particular country within the UK has been clicked and not just that the UK has been clicked!
I am using the following javascript and I am currently just using visual studios "watch" feature to dig down into "results[1]" to see what is contained.
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(51.8052184317649, -4.965819906250006);
var myOptions = {
zoom: 5,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
google.maps.event.addListener(map, 'click', function (event) {
if (confirm('Is this the location you would like to you for your company?')) {
geocoder.geocode({ 'latLng': event.latLng }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (results[1]) {
}
}
});
}
});
}
If I click when the map is zoomed quite far out the country name (ie Wales) comes back with types "administrative_area_level_1" and "political" but when you zoom in it's no longer there as it just gives the address which doesn't contain "Wales".
Does anyone know how I get round this? I'm sure other Brits have come across this?

无法弄清楚如何反向地理编码以获取英国国家/地区，因为我认为这实际上是不可能的！
最终使用邮政编码并以此确定国家/地区！
不是最好的，但它对我有用！
Couldn't work out how to reverse geocode to get a UK country as I think it's actually impossible!
Ended up using postcodes and working out countries by that!
Not the best, but it works for me!
英国国家/地区表示为
administrative_area_level_1结果，请查看本示例中的倒数第二个结果（不要依赖address_components）：https://maps.googleapis.com/maps/api/geocode/json?&latlng =51.641033,-0.647507
UK countries are represented as
administrative_area_level_1results, look at the 2nd last result in this example (do not rely onaddress_componentsfor this):https://maps.googleapis.com/maps/api/geocode/json?&latlng=51.641033,-0.647507
