jquery - 連続自動スクロールdiv jquery

Question

自動スクロールしたいのですが、次のコードを試してみましたが、正常に動作しています。しかし、スクロールを再開したい。

JS:

$(document).ready(function () {
    var containerheight = 0,
        numbercount = 0,
        liheight,
        index = 1,
        timer = null;
    var speed = 75; //px per sec
    var width = $('#vmarquee').outerHeight();
    var curleft = $('#vmarquee').position().top;
    var duration = (width + curleft) * 1000 / speed;
    alert(width);

    function slide() {
        //  var curleft = $('#vmarquee').position().top;
        //  var duration = (width+curleft) * 1000 / speed;

        $("#vmarquee").animate({
            "margin-top": width
        }, duration, function () {

            slide();
        });

        // timer = setTimeout(slide, 2500);
    }

    $("#vmarquee").hover(function () {
        $('#vmarquee').stop();
    }, function () {
        slide();
    });

    slide();
});
