How past parameters with ajaxStetings (ajaxOption depreciated)

Hi,

Excuse my bad english.
ajaxOption depreciated, how can I pass parameters to recover in php

Javascript :
  2. <script type="text/javascript">
  3.   $(function() {
  4.     $("#tabs").tabs(
  5. {
  6.     beforeLoad: function(event, ui)
  7. {
  8. ui.ajaxSettings.type = 'POST';
  9. ui.ajaxSettings.username = 'foo';
  10.         ui.jqXHR.fail(function()
  11. {
  12.           ui.panel.html("Couldn't load this tab. We'll try to fix this as soon as possible. " + "If this wouldn't be a demo." );
  13.         }
  14. );
  15.       }
  16.     });
  17.   });
  18.   </script>

PHP file :
  1. <?php
  2. $_POST['username'];
  3. ?>
Please help me, thanks
