如何從Json輸出獲取特定信息

我正在做一個學校項目，我正在使用Google Geocoding API輸出json。如何從Json輸出獲取特定信息

我不知道如何在變量中存儲輸出的「formatted_address」（見下文），以便日後可以使用這些信息。

這是我正在使用的json輸出的一部分。

"results" : [ 
    { 
    "address_components" : [

到目前爲止，我在我的js文件嘗試這樣的：

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);

如果添加了更多的細節你的問題，我我相信很多人都能幫上忙。你如何存儲數據？ MySql，文本，瀏覽器存儲，會話... brail？ – HappyCoder

感謝您的回覆。我會在這個問題上添加更多細節。 –

請添加實際的JSON輸出，而不是screenShot。 –

你需要訪問它之前，你解析JSON響應：

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);

希望這會工作。

它似乎是這樣做的。謝謝！ :) –

你想用點符號來達到你想要的值。谷歌的地理編碼V3返回數組，所以你要查找的內容如下：

results[0].formatted_address

這裏是一個提醒格式的地址給你一個小提琴：

我希望這是很有幫助。

哇。感謝那！這是比我想象的方式更簡單:) –

當我嘗試這個restaurantAddressRequest.results [0] .formatted_address它沒有工作：/ –

我用getJSON方法的jQuery這樣解決問題：

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); 
});

如果你想以異步方式做到這一點：

//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"); 
       } 

      } 
     });
