Question

我正在做一个学校项目，我正在使用Google地理编码API的json输出。

我不知道如何存储＆＃34; formatted_address＆＃34; （见下文）变量中的输出，以便稍后我可以使用这些信息。

以下是我正在处理的json输出的一部分。

"results" : [
  {
     "address_components" : [

到目前为止，我在我的js文件中尝试这个：

var restourantAddressRequest = "https://maps.googleapis.com/maps/api/geocode/json?latlng="+restLatitude+","+restLongtitude+"&key=API_KEY;
//alert(restourantAddressRequest.results.formatted_address);
$("#restaurant_address").html("Address: " + restourantAddressRequest.results.formatted_address);

Answer 1

您想使用点表示法来获得所需的值。 Google V3 Geocoder会返回一个数组，因此您需要查找以下内容：

results[0].formatted_address

这是一个小提琴，可以为您提醒格式化地址：

我希望这有用。

Answer 2

在访问JSON响应之前，您需要解析它：

var restourantAddressRequest = "https://maps.googleapis.com/maps/api/geocode/json?latlng="+restLatitude+","+restLongtitude+"&key=API_KEY";
var json= JSON.parse(restourantAddressRequest);
//alert(restourantAddressRequest.results.formatted_address);
$("#restaurant_address").html("Address: " + restourantAddressRequest.results.formatted_address);

希望这会奏效。

Answer 3

如果您想异步执行此操作：

//Show that you are loading the data

$("#restaurant_address").html("Address: Loading... ");    

//Set the url:

var url = 'https://maps.googleapis.com/maps/api/geocode/json?latlng="+restLatitude+","+restLongtitude+"&key=API_KEY"';

//Make the Ajax call:


        $.ajax({
            type:  'GET',
            async: true,
            url:   url,
            dataType: "json",

            success: function(responseObject){


                if (responseObject.success)
                {
                    $("#restaurant_address").html("Address: " + ... );

                } else {
                    $("#restaurant_address").html("Address: n/a");
                }

            }
        });

Answer 4

我在jQuery中使用getJSON方法解决了这个问题：

var restaurantAddressRequest = "https://maps.googleapis.com/maps/api/geocode/json?latlng="+restLatitude+","+restLongtitude+"&key=API_KEY";
//alert(restourantAddressRequest.results.formatted_address);

$.getJSON(restaurantAddressRequest,function(jsondata){
    $("#restaurant_address").html("Address: " + jsondata.results[0].jsondata.results[0].formatted_address);
});

如何从Json输出中获取特定信息
