How to get data from dynamic widget OnAuth VKontakte?

Question

JavaScript

<script type="text/javascript" src="https://vk.com/js/api/openapi.js?161"></script>
<script type="text/javascript">
  VK.init({apiId: #####});
</script>

<!-- VK Widget -->
<div id="vk_auth"></div>
<script type="text/javascript">
  VK.Widgets.Auth("vk_auth", {"onAuth":"function(data) {alert(\'user \'+data[\'uid\']+\' authorized\');}"});
</script>

After authorization, you need to display the user ID on the screen.

try without quotes

VK.Widgets.Auth("vk_auth", {"onAuth":function(data) {alert('user '+data['uid']+' authorized')}});
