Javascript從google autocomplete或lat和lng獲取城市名稱

我找到一種方法可以從google autocomplete或lat和lng獲取正確的城市名稱。現在我用這個代碼：Javascript從google autocomplete或lat和lng獲取城市名稱

google.maps.event.addListener(autocomplete, 'place_changed', function() { 
var place = autocomplete.getPlace(); 
for (var i = 0; i < place.address_components.length; i++) { 
    for (var j = 0; j < place.address_components[i].types.length; j++) {     
     if (place.address_components[i].types[j] == "locality") {$("#city").val(place.address_components[i].long_name); 
     }

現在我用一種「地方」的城市名稱，但有時爲其他地址也可能是「administrative_area_level_1」，「administrative_area_level_2」，「administrative_area_level_3」 ...等。如何從地址獲取正確的城市名稱？感謝您的幫助。

對於「列寧，水貂，白俄羅斯」我有這樣的結果：

結果有兩個address_components ...

所以你也使用城市的地點類型？是的，有時它是有效的，但是例如，對於地址「Lenina，Minsk，Belarus」它顯示的城市名稱像「Lenina」，但必須顯示明斯克。 –

你可以添加你的原始問題一個你不能利用的結果的樣本（就像我做的那樣，一個完整的結果JSON）？ –

我將json結果添加到了我的文章中。發現結果中有兩個address_components。我怎樣才能只使用firts address_components？ –
