jQuery doesn"t .load() until .ajax() within callback of .load() is complete?

My problem is that the <div> with the jQuery progress bar ( dnc_scrubber.html ) isn't loaded until all of the other requests are complete.

Is there anyway around this? I want to change the content of #tabs-1 to the progress bar, and animate it while dnc_scrubber.php is doing its work.

The lines.php and progress.php files are used to calculate the percentage of work done by dnc_scrubber.php - which updates the session as it goes along. lines.php and files.php return the session variable.

$('#tabs-1').load('dnc_scrubber.html', function() {

    var querystring = 'col=' + col + '&' + makeQS(files);

    var lines = 0;



    $('#progressbar').progressbar();



    $.ajax({

        url: 'dnc_scrubber.php',

        type: 'POST',

        async: true,

        data: querystring,

        complete: function() {

            for (i = 0; i < files.length; i++) {

                $('#complete').append('<a href="process/MATCHED - ' + files[i] + '">MATCHED - ' + files[i] + '</a><br />');

                $('#complete').append('<a href="process/SCRUBBED - ' + files[i] + '">SCRUBBED - ' + files[i] + '</a><br />');

            }

        }

    });



    $.ajax({

        url: 'lines.php',

        async: true,

        dataType: 'json',

        complete: function(json) {

            lines = json.total;

        }

    });





    function setProgress() {

        if (prog < lines) {

            prog = getProgress();

            $('#progressbar').progressbar('option', 'value', prog);

            setTimeout(setProgress(), 1000)

        } else {

            $('#progressbar').progressbar('option', 'value', 100);

        }

    }



    var prog = getProgress();

    setTimeout(setProgress(), 1000);

});

I have already tried loading the progress bar within the callback function of a .ajax() request with async set to false . The same result happens - the progress bar is not loaded into #tabs-1 until dnc_scrubber.php is complete.

What can I do?
