자바 스크립트로 jSON 데이터를 읽는 중

Question

Google지도 API에서 일부 정보를 JS와의 내 응용 프로그램으로 읽으려고합니다. 하지만 조용한 havent는 반환 된 jSON 객체의 정보에 액세스하는 것에 대해 머리가났습니다. 내 JS 내가 주소 구성 요소에 액세스하려고 ...하지만 객체를 제대로 통과하는 방법이 확실하고

 var site = "./maps/scripts/reverseGeocode/locale.php"; 
     var params = "lat="+lat+"&"+"lng="+lng; 

     var object = system.functions().ajax(site, params); 

      var result = object.address_components[0]; 

      alert(result); 

json으로 개체는 다음과 같다 ...

{ 
    "results" : [ 
     { 
    "address_components" : [

입니다 ... .. 누군가 나를 도울 수 있겠 어.

  "long_name" : "Kirribilli", 
      "short_name" : "Kirribilli", 

Answer 1

이 그것을 수행해야합니다

var long_name = object.address_components[2].long_name; 
var short_name = object.address_components[2].short_name; 

편집 : 당신이 사용하는 것이 좋습니다 JQuery와 아약스가 가져 오는 대신 위해 :

이

var site = "./maps/scripts/reverseGeocode/locale.php"; 
var params = "lat="+lat+"&"+"lng="+lng; 

$.get(site + '/' + params, function(data) { 
    var long_name = data.address_components[2].long_name; 
    var short_name = data.address_components[2].short_name; 
});
