Question

$.getJSON("http://www.geoplugin.net/json.gp?ip=117.201.92.17",function(data){alert(data);});

This code runs fine, but the response of the url, is empty. However if i visit the same URL by copy pasting the url it works. Any ideas why?

According to this page (link):

AJAX and Error: Invalid label

If you are using jQuery for example to
do AJAX calls to the JSON webservice,
you will probably be seeing the
Javascript error Error: Invalid label
To eliminate this error, tag
jsoncallback=? onto the url when
making the jQuery Ajax call to any
JSON webservice eg

$.getJSON("http://www.geoplugin.net/json.gp?jsoncallback=?",
function (data) {
  for (var i in data) {
      document.write('data["i"] = ' + i + '<br/>');
  }
);

So I added that and created a fiddle here (link) to show it working.
