There are some free services out there in the Internet which let you find country and IP-based geolocalization from the client-side IP data.
wipmania is a free JSONP service which can be used to determine visitor’s country. It’s really simple to use:
<script type="text/javascript">
// plain JavaScript example
function jsonpCallback(data) {
alert('Latitude: ' + data.latitude +
'\nLongitude: ' + data.longitude +
'\nCountry: ' + data.address.country);
}
</script>
<script src="http://api.wipmania.com/jsonp?callback=jsonpCallback"
type="text/javascript"></script>
if you use a framework that supports JSONP, like jQuery, you can use:
// jQuery example $.getJSON('http://api.wipmania.com/jsonp?callback=?', function (data) { alert('Latitude: ' + data.latitude + '\nLongitude: ' + data.longitude + '\nCountry: ' + data.address.country); });
Check the above snippet running here.
Instead of an alert dialog (as in the above example), if you want to redirect a URL that takes a US visitor to a .COM address and allows a Canadian visitor passes through normally (for a .ca version of a website with a sister .com version site), simply use a “switch” statement in the “onload” event, check the “country” returned from the json function, then call Server.Transfer (asp.net) or similiar.
