javascript - 使用此谷歌地图 API 自动完成示例。修改这个函数可以得到经纬度吗？

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。然而，该功能只是为了查找地址组件而设置的。我还需要几何的经度和纬度。

计划是将经度和纬度保存到存储中，然后使用 ajax 来获取一些 php 结果。

我相信函数 fillInAddress() 是我需要添加一些内容的地方。

感谢任何帮助!

There is a JSFIDDLE on this google Page(点击后向下滚动，有一个 fiddle 链接，所以我不必向你展示我的 key )

最佳答案

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);
