使用谷歌地理编码api jquery从经度和纬度获取城市名称 [英] get city name from longitude and latitude using google geocoding api jquery

问题描述

我想从经度和纬度获得城市名称.我正在使用以下代码，但是它将返回带有城市名称，邮政编码，省和国家/地区的整个地址.我只想要城市名称.

I want to get city name from longitude and latitude. I am using following code but it is returning the entire address with city name, postal code, province and country. I just want only city name.

     $.ajax({ url:'http://maps.googleapis.com/maps/api/geocode/json?latlng='+position.coords.latitude+','+position.coords.longitude+'&sensor=true',
               success: function(data){
               alert(data.results[4].formatted_address);

               }
               });

请查看地理编码的结果

{
           "long_name" : "Vancouver",
           "short_name" : "Vancouver",
           "types" : [ "locality", "political" ]
        },

由于API数据类型的性质，

推荐答案

formatted_address总是会返回完整的地址字符串.您需要直接在address_components数组中引用位置类型.

formatted_address is always going to return you a full address string, due to the nature of the datatype from the API. You need to directly reference the locality type in the address_components array.

Google Maps Geocoding API

例如，您需要在返回的address_components数组中搜索位置类型:

So for example, you need to search through the returned address_components array for the locality type:

for (var i = 0; i < data.results[4].address_components.length; i++) {
    for (var j = 0; j < data.results[4].address_components[i].types.length; j++) {
        if(data.results[4].address_components[i].types[j] == 'locality') {
            var city_name = data.results[4].address_components[i].long_name;
            alert(city_name);
        }
    }
}
