javascript - jQuery value not getting assigned from ipinfo when expected -

i'm using:

//function obtain current location, used display relevant contact information     $.get("http://ipinfo.io", function(response){         $("#address").html(response.region);//http://jsfiddle.net/zk5fn/2/          $("input[id=address]").val(response.region);      }, "jsonp"); 

to current location contact page. aim can use if address== display various contact numbers etc.

this function updates value of hidden field. i've checked debugger , it's working fine.

i'd value can play it's blank or empty.

i have

$(document).ready(function(){             var testloc = $('#address').val();              if(testloc == ""){                 alert("noes!!!");             }          }); 

which i've placed in same script block within head see if results different, again, it's blank , returns noes alert.

i though waiting document load i'd values assigned/set.

can suggest solution please? i'm sure there's simple fix , it's killing me

edit: html

<input type="hidden" name="address" id="address"/> 

edit solution:

    <script>     $(function() {         $.ajax({url:"http://ipinfo.io",datatype:'jsonp'})             .success(function(response){                 $("#address").val(response.region);                 $("input[id=address]").val(response.region);                   var testloc = $('#address').val();                 if(testloc == ""){                     alert("noes!!!");                 }else{                     alert("jquery can suck my...")                 }             });     });  </script> 

i'd recommend putting $.get request inside document.ready function.

note ready function called dom ready, if ajax returns before then, element you're filling value may not ready.

$(function() { // shorthand $(document).ready(     $.get({url"http://ipinfo.io",datatype:'jsonp'})     succsss(function(response){         // response     }); });
