我正在寻找像maxmind或其他人一样的免费服务（我真的不在乎什么）我想要一个不同的广告对于美国访问者。
非常感谢！
2astalavista：您的示例正常。这就是我所做的，它仍然没有用。
< html>
< head>
< title> Geo Test< / title>
< script type ='text / javascript'src ='http：//www.101greatgoals.com/wp-includes/js/jquery/jquery.js？ver = 1.7.1'>< /脚本>
< script>
$（document）.ready（function（）{
$ .getJSON（http://smart-ip.net/geoip-json?callback=？，
函数（数据） ）{
console.log（data）;
var c = data.countryCode;
if（c ==US|| c ==US）{
document.getElementById（'ddd'）。innerHTML ='US';} else {
document.getElementById（'ddd'）。innerHTML ='Not US';}
/ *
this服务需求ip
var ip = data.host;
alert（ip）;
$ .getJSON（http://freegeoip.net/json/\"+ip,
function（data）{
console.log（data）;
}
）; * /
}
）;
}） ;？
< / script>
< / head>
< body>
< div id =ddd>< / div>
< / body>
< / html>
不知道它是服务器（亚马逊）还是CDN（cotendo）....
我发现了这些：修复包含链接！
现在它有效：）
< html>
< head>
< title> Geo Test< / title>
< script type ='text / javascript'src ='http：//code.jquery.com/jquery-latest.min.js'>< / script>
< script>
$（document）.ready（function（）{
$ .getJSON（http://smart-ip.net/geoip-json?callback=？，
函数（数据） ）{
console.log（data）;
var c = data.countryCode;
if（c ==US|| c ==US）{
document.getElementById（'ddd'）。innerHTML ='US';} else {
document.getElementById（'ddd'）。innerHTML ='Not US';}
}
）;
}）;
< / script>
< / head>
< body>
< div id =ddd>< / div>
< / body>
< / html>
Do you know of any way to do it? real example...?
I am looking for a free service like maxmind or others (I really don't care what) and I would like to have a different ad for US visitors.
Thanks a lot!
2astalavista: Your example works fine. This is what I did and it's still not working.
<html>
<head>
<title>Geo Test</title>
<script type='text/javascript' src='http://www.101greatgoals.com/wp-includes/js/jquery/jquery.js?ver=1.7.1'></script>
<script>
$(document).ready( function() {
$.getJSON( "http://smart-ip.net/geoip-json?callback=?",
function(data){
console.log(data);
var c = data.countryCode;
if(c=="US" || c=="US" ){
document.getElementById('ddd').innerHTML = 'US'; } else {
document.getElementById('ddd').innerHTML = 'Not US';}
/*
this service needs ip
var ip = data.host;
alert(ip);
$.getJSON( "http://freegeoip.net/json/"+ip,
function(data){
console.log(data);
}
);*/
}
);
});?
</script>
</head>
<body>
<div id="ddd"></div>
</body>
</html>
Don't know if it's the server (amazon) or the CDN (cotendo)....
I found these: http://freegeoip.net/static/index.html and http://smart-ip.net
$.getJSON( "http://smart-ip.net/geoip-json?callback=?",
function(data){
var c = data.countryCode;
if(c=="US" || c=="USA" )
alert("American visitor!");else
alert("Not american visitor! ("+c+")");
}
);
Why is your code not working?
1) You should take care of the error messages:
Uncaught SyntaxError: Unexpected token ?
remove ?
2) error again:
Uncaught TypeError: Property '$' of object [object Window] is not a function
this means jquery does not work for some reason.
fix include link according to this!
now it works :)
