我找到了一种从谷歌自动完成或纬度和经度获取正确城市名称的方法。现在我使用这段代码:
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);
}
现在我使用“locality”类型作为城市名称，但有时对于其他地址，它可能是“administrative_area_level_1”、“administrative_area_level_2”、“administrative_area_level_3”等。 如何从地址中获取正确的城市名称？ 感谢帮助。
对于“Lenina，Minks，白俄罗斯”，我有这样的结果:
