Actually, I need the user ID of the authorized user to be displayed in a pop-up window after Vkontakte authorization.
Test site inf2.ru
code is as follows:

<!DOCTYPE html>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script src="jquery.js"></script>
  <script src="http://userapi.com/js/api/openapi.js" type="text/javascript" charset="windows-1251"></script>
<script src="//vk.com/js/api/openapi.js" type="text/javascript"></script>
<script language="javascript">
VK.init({
  apiId: 5237076
});
</script>
</head>
<body>
<div id="vk_auth" style="display: none;"></div>
<script type="text/javascript">
$(document).ready(function() {


VK.Widgets.Auth("vk_auth", {width: "200px", authUrl: 'http://inf2.ru/index.php', onAuth: function(data) 
      {
      location.reload();
      } 
    });


VK.Auth.getLoginStatus(function(response) { 
  if (response.session) { 
    /* Авторизованный в Open API пользователь */ 
  } else { 
$('#vk_auth').css('display','block');
  } 
}); 



 VK.Api.call('users.get', {}, function(r) {
    alert('Привет, ' + r.response[0].uid);
});  


 


});

</script>

</body>
</html>

After authorization, an unauthorized user does not show iD, you have to reload the page to show it. How to make it show without reboot?
