Google地图，根据国家/地区代码可视化国家/地区

标签： javascript google-maps

我有 CountryCodes 的列表，我想基于这些CountryCodes生成GoogleMap可视化。例如对于中国我有“CN”我希望能够生成这样的可视化：

中心和 zoom 必须是自动的，因为我拥有的唯一信息是CountryCode

更新

我尝试使用此代码：JSFiddle playground，我可以居中和缩放基于CountryName但不基于CountryCode。

geocoder.geocode({"address": address}, function(results, status) {
  if (status == google.maps.GeocoderStatus.OK) {
    map.setCenter(results[0].geometry.location);
    map.fitBounds(results[0].geometry.bounds);
  } else {
    alert('Geocode was not successful for the following reason: ' + status);
  }
});

当address是CountryName时它可以工作，但我不知道当address是CountryCode时如何使它工作。

对2个字符的ISO 3166代码以及字符串“country”进行地理编码对我有用：

var geocoder;
var map;

function initialize() {
  geocoder = new google.maps.Geocoder();
  var latlng = new google.maps.LatLng(-34.397, 150.644);
  var mapOptions = {
    zoom: 8,
    center: latlng
  }
  map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);

function codeAddress(selectItem) {
  var address = document.getElementById('addr_sel')[selectItem.selectedIndex].value;
  geocoder.geocode({
    "address": address + " country"
  }, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
      map.setCenter(results[0].geometry.location);
      map.fitBounds(results[0].geometry.bounds);
      document.getElementById('address').value = results[0].formatted_address;
    } else {
      alert('Geocode was not successful for the following reason: ' + status);
    }
  });
}

$("#geocode_button").on("click", codeAddress);

initialize();
     #map-canvas {
       height: 400px;
       margin: 0px;
       padding: 0px;
       border: 1px solid red;
     }
