有没有办法从客户端确定访客国家？ [英] Is there a way to determine a visitors country from the client?

问题描述

我使用谷歌地图和地理编码API在用户输入邮政编码后检索用户lat / lng，但我想限制邮政编码到该用户国家，所以我不会以多个结果。

有没有一种方法可以从客户端可靠地确定访客来源国家可能使用jquery或可能解码用户代理？

我的电话会看起来像这样：

  var country = ??? 
 var postcode = document.getElementById（'postcode'）。value +'，'+ country; 
 
 var geocoder = new google.maps.Geocoder（）; 
 geocoder.geocode（{'address'：postcode}，function（results，status）{
 if（status == google.maps.GeocoderStatus.OK）{
 ... 
} 
}）; 
  

有什么想法？

解决方案

为了不依赖第三方，您可以通过使用谷歌的加载器。 这是一个很好的例子 ，加载Google Maps API和ClientLocation。

I'm using google maps and the geocoding API to retrieve a users lat/lng after they enter a zip/postal code but I want to limit the zip/postal codes to that users country so I don't end up with multiple results.

Is there a way to reliably determine a visitors country of origin from the client maybe using jquery or possible decoding the user agent somehow?

My call would end of looking something like this:

var country = ???
var postcode = document.getElementById('postcode').value + ', ' + country;

var geocoder = new google.maps.Geocoder();         
geocoder.geocode({ 'address': postcode }, function (results, status) {          
   if (status == google.maps.GeocoderStatus.OK) {  
       ...
   }
});

Any thoughts?

解决方案

For the benefit of not relying on a third-party, you can get the client's location by using Google's Loader. Here's a great example of this in use, loading the Google Maps API and ClientLocation.
