Google Maps API返回「未定義」

我在查詢Google地圖地理編碼API的字符串。我在控制檯中看到一個返回，所以我知道我連接正確，但if語句中的內容返回「未定義」。任何想法，爲什麼會這樣？Google Maps API返回「未定義」

$(document).ready(function(){ 

     // Search Submit 
     $("#search").submit(function(event){ 
      event.preventDefault("", function(){ 
        // 
        }); 

      name = $("#search-name").val(); 
      console.log("Search term at submit is: "+name); 

      // Send to Google Geocoding API 

      var geocoder = new google.maps.Geocoder(); 

      geocoder.geocode({ 
         address : name 
        }, function(results, status){ 

         if (status == google.maps.GeocoderStatus.OK) { 

           console.log("results after query: "+ results.formatted_address + "\n" + results.length + " QTY Posts"); 
        } 

      ); 
     }); 
});

結果是數組而不是對象。對於對象使用位置或使用foreach來讀取所有返回。

嘗試將results.formatted_address更改爲結果[0] .formatted_address。

var map; 
 
var addressField; 
 
var geocoder; 
 

 
$(document).ready(function() { 
 
    // Define map options 
 
    var mapOptions = { 
 
     center: new google.maps.LatLng(57.698254, 12.037024), 
 
     zoom: 16, 
 
     mapTypeId: google.maps.MapTypeId.HYBRID, 
 
     panControl: true, 
 
     zoomControl: true, 
 
     mapTypeControl: true, 
 
     scaleControl: true, 
 
     streetViewControl: true, 
 
     overviewMapControl: true 
 
    }; 
 

 
    // Define map 
 
    map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions); 
 

 
    // Define Gecoder 
 
    geocoder = new google.maps.Geocoder(); 
 

 
    // Init searchbox 
 
    initSearchBox(); 
 
}); 
 

 
function initSearchBox() { 
 
    // Add searchbox 
 
    var searchControlDiv = document.createElement('div'); 
 
    var searchControl = new SearchControl(searchControlDiv, map); 
 

 
    searchControlDiv.index = 1; 
 
    map.controls[google.maps.ControlPosition.TOP_CENTER].push(searchControlDiv); 
 
} 
 

 
function SearchControl(controlDiv, map) { 
 
    // Set CSS styles for the DIV containing the control 
 
    // Setting padding to 5 px will offset the control 
 
    // from the edge of the map. 
 
    controlDiv.style.padding = '5px'; 
 

 
    // Set CSS for the control border. 
 
    var controlUI = document.createElement('div'); 
 
    controlUI.style.backgroundColor = 'white';
