【中文标题】使用这个 google maps API 自动完成示例。这个函数可以修改得到经度和纬度吗？【英文标题】：Using this google maps API auto-complete example. Can this function be modified get the longitude and latitude? 【发布时间】：2017-12-16 04:04:50 【问题描述】：如果 GPS 不可用，我需要使用此自动完成表单来获取用户位置。但是，此功能仅用于查找地址组件。我还需要几何中的经度和纬度。
计划是将经度和纬度保存到存储中，然后将其ajax以获得一些php结果。
我相信函数 fillInAddress() 是我需要添加内容的地方。
感谢任何帮助！
There is a JSFIDDLE on this google Page （点击后向下滚动，有一个指向小提琴的链接，所以我不必给你看我的钥匙）

【问题讨论】：
Populate the longitude and latitude using google maps API的可能重复 Javascript - Google Maps - Autofill的可能重复 【参考方案1】：我在这里找到了答案。
Lat and Long auto complete
function initialize()
var address = (document.getElementById('my-address'));
var autocomplete = new google.maps.places.Autocomplete(address);
autocomplete.setTypes(['geocode']);
google.maps.event.addListener(autocomplete, 'place_changed', function()
var place = autocomplete.getPlace();
if (!place.geometry)
return;
var address = '';
if (place.address_components)
address = [
(place.address_components[0] && place.address_components[0].short_name || ''),
(place.address_components[1] && place.address_components[1].short_name || ''),
(place.address_components[2] && place.address_components[2].short_name || '')
].join(' ');
);
function codeAddress()
geocoder = new google.maps.Geocoder();
var address = document.getElementById("my-address").value;
geocoder.geocode( 'address': address, function(results, status)
if (status == google.maps.GeocoderStatus.OK)
alert("Latitude: "+results[0].geometry.location.lat());
alert("Longitude: "+results[0].geometry.location.lng());
else
alert("Geocode was not successful for the following reason: " + status);
);
google.maps.event.addDomListener(window, 'load', initialize);
