asked on What is wrong with this code?
I include this in one of the client side Javascripts:
It is executed from a click button event and always returns 'Unknown IP'. If I test the URL in my browser, I get the correct json reply.
function getIP() {
var ipAddress = 'Unknown IP';
$.ajax({
dataType: "json",
url: "http://smart-ip.net/geoip-json?callback=?",
async: false,
success: function(data) {
ipAddress = data.host;
}
});
return ipAddress;
}
It is executed from a click button event and always returns 'Unknown IP'. If I test the URL in my browser, I get the correct json reply.

In your code, you have no other code that continues while the request is being made. Your request will be made asynchronously and the variable ipAddress will not contain the client IP when it is returned:
This is why I want to execute the code synchronously so that the code will wait until the fetch for information is done and THEN return the result.

var ipAddress = 'Unknown IP';
function getIP() {
return $.getJSON("http://smart-ip.net/geoip-json?callback=?");
}
getIP().then(function(info) {
ipAddress = info.host;
});
alert(ipAddress);

OK - I see, thank you very much ! :D
async (default: true)
Type: Boolean
By default, all requests are sent asynchronously (i.e. this is set to true by default). If you need synchronous requests, set this option to false. Cross-domain requests and dataType: "jsonp" requests do not support synchronous operation.
You're using JSONP (callback=?)
You're doing a cross-domain requests (http://smart-ip.net)
