Question

我需要从json文件下面打印postal_code值，

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "286",
               "short_name" : "286",
               "types" : [ "street_number" ]
            },
            {
               "long_name" : "West El Camino Real",
               "short_name" : "W El Camino Real",
               "types" : [ "route" ]
            },
            {
               "long_name" : "Old Mountain View",
               "short_name" : "Old Mountain View",
               "types" : [ "neighborhood", "political" ]
            },
            {
               "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" : "United States",
               "short_name" : "US",
               "types" : [ "country", "political" ]
            },
            {
               "long_name" : "94040",
               "short_name" : "94040",
               "types" : [ "postal_code" ]
            },
            {
               "long_name" : "2606",
               "short_name" : "2606",
               "types" : [ "postal_code_suffix" ]
            }
         ],
         "formatted_address" : "286 W El Camino Real, Mountain View, CA 94040, USA",
         "geometry" : {
            "location" : {
               "lat" : 37.3833211,
               "lng" : -122.0782706
            },
            "location_type" : "ROOFTOP",
            "viewport" : {
               "northeast" : {
                  "lat" : 37.38467008029149,
                  "lng" : -122.0769216197085
               },
               "southwest" : {
                  "lat" : 37.3819721197085,
                  "lng" : -122.0796195802915
               }
            }
         },
         "place_id" : "ChIJieTN_yu3j4AR6cF-aEhdc58",
         "types" : [ "street_address" ]
      }

   "status" : "OK"
}

我已编写以下代码以获取和打印响应。

$.ajax({
  dataType: "json",
  url: 'https://maps.googleapis.com/maps/api/geocode/json?latlng=37.383253,-122.078075&sensor=false',
  data: latlog,
  success: function (response) {  
  $("#response").html(JSON.stringify(response["results"], null, 4));
  }
});

这会打印几乎整个对象。如何只打印postal_code值94040？

您的JSON错误，请查看演示代码以查看正确的语法。

如何只打印postal_code值94040？

您需要访问地址组件并过滤掉类型为postal_code

的对象

试试这个

obj.results[0].address_components.filter( function(obj){ 
  return obj.types.indexOf("postal_code") != -1 
})[0].long_name
