Jquery - Get client computer IP address

We can use the appspot IPAddress provider server , that returns the ip of the requesting client in the Json format. Use the callback function and retrieve the IP Address. If you hit the following url, you will find the json response. http://jsonip.appspot.com/ {"ip": "111.22.333.444", "address":"111.22.333.444"}

The following JQuery function retrieves the IP on a button click.

$(function() {
$('btn').click(function()
{
$.getJSON("http://jsonip.appspot.com?callback=?",function(jsonResult){
     alert( "IP Adress = " + jsonResult.ip);
});
});
