javascript - 使用 google api 进行反向查找来获取 iso 代码

Question

我在这篇文章中找到了一些代码:How can I get the country and region code using geolocation instead of full country and region names

我想获取用户的 iso 国家代码(2 位数字)。

但我不明白为什么它不起作用？在 chrome 控制台中，我在第 40 行收到“;uncaught SyntaxError: Unexpected token ;”

jsfiddle:http://jsfiddle.net/M9kzT/

<script>
    var region = "";
    var country = "";
    function getLocation()
    {
        if (navigator.geolocation)
          {
              navigator.geolocation.getCurrentPosition(showPosition,noGeolocation);
          } else {
              console.log('nope');
          }
    }
    function showPosition(position)
    {
        var geocoder = new google.maps.Geocoder();
        var latlong = new google.maps.LatLng(position.coords.latitude,position.coords.longitude);
        geocoder.geocode({'latLng': latlong}, function(results, status) {
              if (status == google.maps.GeocoderStatus.OK) {
                  if (results[0]) {
                    for (var i = 0; i < results[0].address_components.length; i++)
                    {
                        var longname = results[0].address_components[i].long_name;
                        var type = results[0].address_components[i].types;
                        if (type.indexOf("administrative_area_level_1") != -1)
                        {
                            region = longname;
                        }
                        if (type.indexOf("country") != -1)
                        {
                            country = short_name;
                        }
                      }
              }
        });
    }
  }
    function noGeolocation()
    {
        console.log('nope2');   
    }

    getLocation();
</script>

您有 2 个 } 放错地方:缺少一个，一个不是必需的:

    function showPosition(position) {
        var geocoder = new google.maps.Geocoder();
        var latlong = new google.maps.LatLng(position.coords.latitude,position.coords.longitude);
        geocoder.geocode({'latLng': latlong}, function(results, status) {

            if (status == google.maps.GeocoderStatus.OK) {
                if (results[0]) {
                    for (var i = 0; i < results[0].address_components.length; i++) {
                        var longname = results[0].address_components[i].long_name;
                        var type = results[0].address_components[i].types;
                        if (type.indexOf("administrative_area_level_1") != -1) {
                            region = longname;
                        }
                        if (type.indexOf("country") != -1) {
                            country = short_name;
                        }
                    }
                }
            } 
        });
    }

///}

更新:更改了函数showPosition()以记录长短国家名称:

function showPosition(position) {
    var geocoder = new google.maps.Geocoder();
    var latlong = new google.maps.LatLng(position.coords.latitude,position.coords.longitude);
    geocoder.geocode({'latLng': latlong}, function(results, status) {

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

                    for (var typeIdx = 0; typeIdx < types.length; typeIdx++) {
                        if (types[typeIdx] == 'country') {
                            console.log(results[0].address_components[i].long_name);
                            console.log(results[0].address_components[i].short_name);
                        }
                    }
                }
            }
        } 
    });
}
