autocomplete (sending an additional parametr to server request)

autocomplete (sending an additional parametr to server request)

Hello!
I'm trying to use autocomplete with data source from php.
I need to make the request to my script with the 2 parametrs.
  1. getset.php?get=table&term=some

But still don't understand how.

I need to do something like this:

  1. $( "#autocomplete" ).autocomplete({
        sourcel:'/getset.php',
        params: {
            'get': 'table'
        };
    });

But there is no params option in http://api.jqueryui.com/autocomplete/#option-source

Could you help me to solve this problem?
