从 Google 地理编码 API 返回邻居？答案

【问题标题】：Returning Neighborhood from Google geocode API?从 Google 地理编码 API 返回邻居？
【发布时间】：2019-01-15 01:23:17
【问题描述】：

我无法从 google geocode api 返回社区名称。我只是试图通过过滤来检索它，但我收到“过滤器不是函数”错误。

我在想……filter.results(item => item.types === 'neighborhood')

但我也想返回邻域类型的 long_name。

感谢您的帮助！

这是他们文档中的一个示例对象：

【问题讨论】：

请分享产生错误的代码
filter.results 不起作用，如果要从结果数组中过滤某些内容，则需要使用 results.filter，
感谢@karthick，关于如何获取我正在寻找的信息有什么建议吗？
@Dres，我附上了一个例子

我附上了一个例子，

结果集通常会有很多地址组件，因为您要过滤的条件位于嵌套数组中，您需要先访问该数组。

以下行将输出一个地址数组，根据您的要求，您可以选择全部显示或选择第一个。

var address = sample.results.reduce(function(prev, result) {
      return prev.concat(result.address_components.filter((item) => item.types.indexOf('route') > -1));
},[]);

var sample = {
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "1600",
               "short_name" : "1600",
               "types" : [ "street_number" ]
            },
            {
               "long_name" : "Amphitheatre Pkwy",
               "short_name" : "Amphitheatre Pkwy",
               "types" : [ "route" ]
            },
            {
               "long_name" : "Mountain View",
               "short_name" : "Mountain View",
               "types" : [ "locality", "political" ]
            },
            {
               "long_name" : "Santa Clara County",
               "short_name" : "Santa Clara County",
               "types" : [ "administrative_area_level_2", "political" ]
            },
            {
               "long_name" : "California",
               "short_name" : "CA",
               "types" : [ "administrative_area_level_1", "political" ]
            },
            {

            {
               "long_name" : "94043",
               "short_name" : "94043",
               "types" : [ "postal_code" ]
            }
         ],
         "formatted_address" : "1600 Amphitheatre Parkway, Mountain View, CA 94043, USA",
         "geometry" : {
            "location" : {
               "lat" : 37.4224764,

         "types" : [ "street_address" ]
      }
   ],
   "status" : "OK"
};

var address = sample.results.reduce(function(prev, result) {
      return prev.concat(result.address_components.filter((item) => item.types.indexOf('route') > -1));
},[]);
        
console.log(address[0]," :: " , address[0].long_name ) // this will retrieve the very first filtered value
