<p>Please help add slide effect when changing divs (I found example code here):</p>

<pre><code>$(function () {
    var counter = 0,
        divs = $('#update1, #update2, #update3');
    function showDiv () {
        divs.hide()
            .filter(function (index) { return index == counter % 3; })
            .show('fast');
        counter++;
    };
    showDiv();  
    setInterval(function () {
        showDiv();
    }, 10 * 1000);  

});
</code></pre>
