<script type="text/javascript" src="http://diafan/kabinet/js/jquery-1.9.1.min.js"></script> <script type="text/javascript" src="http://diafan/kabinet/js/jquery-ui/jquery-ui-1.10.3.min.js"></script> 

autocomplete initializer:

$('#suname').autocomplete({source: getusers,     minlength: 3,     select: setsearchuser,     focus: function(){return false;},     change: function(event,ui) {         if(ui.item==null)             $('#suname').val('');     }  });
