чтение в jSON данных с javascript

Question

Пытается прочитать в некоторой информации из Google Maps api в мое приложение с JS. Но хаус-тишина обрушилась на доступ к информации в возвращаемом объекте jSON. My JS является ...

 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); 

Объект JSon выглядит следующим образом ...

{ 
    "results" : [ 
     { 
    "address_components" : [ 
     { 
      "long_name" : "24",

Я пытаюсь получить доступ к адресной компонент ... но я не уверен, как пройти объект правильно .. может кто-то мне помочь.

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

Answer 1

Это следует сделать это:

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

EDIT: предлагаю вам использовать JQuery Ajax вместо того, чтобы для выборки:

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; 
});
