How to get country code information using geonames service api not the html5 location object thing
提问by arsenal
I am trying to get the country code of the user's current location using Geonames Servcie API. And I believe geonames service API will return me two letter country code instead of three letter country code and I need three letter country code. So for this, I have made the mapping between two letter country code and three letter country code.
我正在尝试使用 Geonames Servcie API 获取用户当前位置的国家/地区代码。我相信 geonames 服务 API 会返回两个字母的国家代码而不是三个字母的国家代码，我需要三个字母的国家代码。为此，我做了两字母国家代码和三字母国家代码之间的映射。
Below is my code, and some how, my alert box is not working at all. I am pretty much sure I am missing something?
下面是我的代码，以及一些方法，我的警报框根本不起作用。我很确定我错过了什么？
<html>
<head>
<title>Visitor's location</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script>
$(document).ready( function() {
$.getJSON('http://ws.geonames.org/countryCode', {
lat: position.coords.latitude,
lng: position.coords.longitude,
type: 'JSON'
}, function(result) {
alert('Country: ' + result.countryName + '\n' + 'Code: ' + result.countryCode);
$('#newURL').attr('href','https://www.google.com&jobid='+result.countryCode);
});
});
</script>
</head>
<body>
<a id="newURL">URL</a>
</body>
</html>
What wrong I am doing in my above code? Below is the error I am getting on the console.
我在上面的代码中做错了什么？以下是我在控制台上遇到的错误。

Using HTML5 Geolocation you could do :
使用 HTML5 地理定位，您可以执行以下操作：
$(document).ready( function() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
$.getJSON('http://ws.geonames.org/countryCode', {
lat: position.coords.latitude,
lng: position.coords.longitude,
type: 'JSON'
}, function(result) {
alert('Country: ' + result.countryName + '\n' + 'Code: ' + result.countryCode);
$('#newURL').attr('href','https://www.google.com&jobid='+result.countryCode);
});
});
}
});
Or you could use a service:
或者您可以使用服务：
$(document).ready( function() {
$.getJSON("http://freegeoip.net/json/", function(result){
alert('Country: ' + result.country_name + '\n' + 'Code: ' + result.country_code);
$('#newURL').attr('href','https://www.google.com&jobid='+result.country_code);
});
});
