Does google js api make XHR?

Does google js api make XHR?

I am trying to deconstruct an autocomplete that someone else wrote who is even more clueless than me. She basically did a cut and paste of an example she found somewhere and it worked. This example uses google apis, so I am trying to find out if google api makes the XHR or what is going on because I want local copies of jquery, ui, etc. Let me show you the code and please if there is a brief explanation as to why it would work but attempting the same with latest versions of jquery, and a theme roller UI will not:

  1. <head>
            <title>Uses google api</title>
            <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
            <link rel="stylesheet" type="text/css" href="css/jquery.autocomplete.css" />
            <script src="http://www.google.com/jsapi"></script> 
            <script>
                google.load("jquery", "1");
            </script>






  2. <body>
            <div>
                <input type="text" id="auto">
                <script>
                    $('#auto').autocomplete('getdata.jsp')
                </script>
               
            </div>
        </body>







So this works, but when I replace the google stuff with my copies of jquery, etc it does not.  So is google taking care of the XHR or what?  Thanks for any explanation.
