通过谷歌地图地理代码的jquery / ajax从经度/纬度获取城市/州？ [英] Get City/State from Latitude/Longitude via jquery/ajax with google maps geocode?

问题描述

我已经看到了这个概念的一些jscript / jquery实现，在这里你可以输入一个邮政编码并从谷歌地图api中获得一个长/纬度。然而，就我而言，我已经有了一组坐标，并且想知道当我们提供它时，是否可以从API动态获取文本City，State的结果通过jquery的长/纬度？

谢谢！

解决方案

是一个名为反向地理编码的过程，而且Google有相当丰富的文档。

举例如下：

  $。ajax（{url：'http：/ /maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true'，
成功：函数（数据）{
 alert（data.results [0 ] .formatted_address）; 
 / *或者你可以遍历城市和州的组件* / 
} 
}）; 
  

I've seen a few jscript/jquery implementations of this concept in reverse, where you can enter a zip code and get a long/lat from the google maps api.

However, in my case, I already have a set of coordinates and was wondering if its possible to dynamically get a textual City, State result from the API when we feed it the long/latitude via jquery?

Thanks!

解决方案

This is a process called reverse geocoding, and Google have quite extensive documentation on it.

An example would be:

$.ajax({ url:'http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true',
         success: function(data){
             alert(data.results[0].formatted_address);
             /*or you could iterate the components for only the city and state*/
         }
});
