[jQuery] Re: jcarousel autostart

My callback goes as follows:

function mycarousel_initCallback(carousel)
{
<?php if($slider == 'auto') { ?>
// Disable autoscrolling if the user clicks the prev or next
button.
carousel.buttonNext.bind('click', function() {
carousel.startAuto(0);
});

carousel.buttonPrev.bind('click', function() {
carousel.startAuto(0);
});

// Pause autoscrolling if the user moves with the cursor over the
clip.
carousel.clip.hover(function() {
carousel.stopAuto();
}, function() {
carousel.startAuto();
});
<?php } ?>
};

Next I have a function which handles the ajax stuff for the cookie and
the success output:

function getscrolltype(what) {
$.get('autoscroll.php',{scrollmodus: what},function(returned_data)
{
if(what == "auto") {
$("#autoscroll_output").html("Automatisch scrollen");
}

if(what == "manuell") {
$("#autoscroll_output").html("Manuell scrollen");
}

}
);
}

The switch I realised as follows:
<div id="autoscroller">
<h4>Projektfenster:</h4>
<ul>
<li><a href="#" onclick="getscrolltype('auto');"
id="autoscroll">Automatisch scrollen</a></li>
<li><a href="#" onclick="getscrolltype('manuell');"
id="manuellscroll">Manuell scrollen</a></li>
</ul>

Gewählt: <span id="autoscroll_output"><?php if
($slider=="auto"){
echo "Automatisch scrollen";
} else { echo "Manuell scrollen";
}?></span>
</div>

Finally my little page "autoscroll.php" that sets the php cookie and
responds:

<?php
require_once('includes/config.inc.php');

$slider= $_GET['scrollmodus'];
if($slider != "auto" && $style != "manuell"){
$slider = "manuell";
}

setcookie("info_autoscroll", $slider, time()+(604800 *
$styleduration));

echo $slider;
?>

So what I trying to reach without sucess is to start/stop autoscroll
from the javascript function getscrolltype above:

function getscrolltype(what) {
$.get('autoscroll.php',{scrollmodus: what},function(returned_data)
{
if(what == "auto") {
$("#autoscroll_output").html("Automatisch scrollen");

*** Start the Autoscroll of my
jcarousel now ***
}

if(what == "manuell") {
$("#autoscroll_output").html("Manuell scrollen");

*** Stop the Autoscroll of my
jcarousel now ***

}

}
);
}

I tried several things, but nothing worked out for me. The PHP part
works well, but it obvious only comes out, if the Visitor clicks on a
link. What I want is to start/stop Autoscroll immediately. Is that
possible?

Hope I described my Problem a lot better. Sorry for my English, I am
german.

Any help is greatly apreciated, I keep the fingers cross, that
somebody couls help me out of this. Thank you.
