Reverse Geocoding (Adresse durch Breiten- und Längengrad erzeugen)

Question

Ich habe dieses JSON-Objekt, wenn ich die Google Reverse Geocodierung API durch mein Projekt .. Aber Problem ist, dass ich brauche nur "Formular_Adresse" Teil, der unter "Ergebnisse" -Array ist, aber nicht wissen, wie man das macht.gut mir helfen. Ich bin frisch in Programmierung .. Jetzt Wie werde ich Karte in Sicht von diesem Controller-Code .. Ich habe Breiten- und Längengrad in Liste Objekt "Verkauf" .. und auch ich habe Standort, die ich von Google API.

können Sie formatted_address von results[0].formatted_address von "Ergebnisse" Array

var geocoder; 
 
var map; 
 
var infowindow = new google.maps.InfoWindow(); 
 
var marker; 
 

 
function initialize() { 
 
    geocoder = new google.maps.Geocoder(); 
 
    map = new google.maps.Map(document.getElementById("map"), { 
 
    zoom: 8, 
 
    center: new google.maps.LatLng(12.960752, 77.641934), 
 
    mapTypeId: google.maps.MapTypeId.ROADMAP 
 
    }); 
 
} 
 

 
function codeLatLng() { 
 
    if (marker && marker.setMap) { 
 
    marker.setMap(null); /*clear previous marker*/ 
 
    } 
 
    var input = document.getElementById("latlng").value; 
 
    var latlngStr = input.split(",", 2); 
 
    var lat = parseFloat(latlngStr[0]); 
 
    var lng = parseFloat(latlngStr[1]); 
 
    var latlng = new google.maps.LatLng(lat, lng); 
 
    geocoder.geocode({ 
 
    'latLng': latlng 
 
    }, function(results, status) { 
 
    if (status == google.maps.GeocoderStatus.OK) { 
 
     if (results[0]) { 
 
     map.setZoom(11); 
 
     marker = new google.maps.Marker({ 
 
      position: latlng, 
 
      map: map 
 
     }); 
 
     infowindow.setContent(results[0].formatted_address); 
 
     infowindow.open(map, marker); 
 
     /*formatted address*/ 
 
     document.getElementById('formatted_address').innerText = results[0].formatted_address 
 

 
     } else { 
 
     alert("No results found"); 
 
     document.getElementById('formatted_address').innerText = "No result" 
 
     } 
 
    } else {
