javascript - 使用 JS 函数的地理编码结果 - 地址拆分

问题描述

我对地理编码器功能有疑问。这是我的 JS 函数：

function init_map() {
            searchLanLon();
            var latitudine = document.getElementById('lat').value;
            var longitudine = document.getElementById('lng').value;

            var myLatLng = new google.maps.LatLng(latitudine, longitudine);

            var geocoder = new google.maps.Geocoder();
            geocoder.geocode({ 'location': myLatLng }, function (results, status) {
                if (status == google.maps.GeocoderStatus.OK) {
                    var options = {
                        zoom: 15,
                        center: myLatLng,
                        mapeTypeId: google.maps.MapTypeId.ROADMAP
                    };
                    var map = new google.maps.Map(document.getElementById('map'), options);
                    var marker = new google.maps.Marker({ position: myLatLng, map: map, draggable: true });
                    google.maps.event.addListener(marker, "dragend", function () {
                        document.getElementById('address').value = results[0].formatted_address;

                    });
                    document.getElementById('address').value = results[0].formatted_address;

                } else {
                    alert("Problema nella ricerca : " + status);
                }
            });

        }
        window.onload = init_map;

该功能有效，但我需要一个分为街道、号码、城市、邮政编码的地址，以便将其保存在具有此字段的数据库中。

如何拆分地址？谢谢

检查地理编码文档https://developers.google.com/maps/documentation/geocoding/intro#GeocodingResponses

您正在使用formatted_address，但您对每个结果都有更多信息address_components

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "1600",
