smooth scrolling script needed

[serkan sendur]

i want to have my page scroll to a position smoothly, i use javascript scrollIntoView method to provide scrolling for the page, but it moves suddenly. i want the user to keep trace of where she/he is scrolling.

thanks in advance

i search for a ready script for smooth scrolling but i couldnt find any. So i did it myself as follows, it works perfectly

function elementPosition(obj) {
        var curleft = 0, curtop = 0;

        if (obj.offsetParent) {
            curleft = obj.offsetLeft;
            curtop = obj.offsetTop;

            while (obj = obj.offsetParent) {
                curleft += obj.offsetLeft;
                curtop += obj.offsetTop;
            }
        }

        return { x: curleft, y: curtop };
    }

  function ScrollToControl(id)
        {
            var elem =  document.getElementById(id);
            var scrollPos = elementPosition(elem).y;
            scrollPos = scrollPos - document.documentElement.scrollTop;
            var remainder = scrollPos % 50;
            var repeatTimes = (scrollPos - remainder) / 50;
            ScrollSmoothly(scrollPos,repeatTimes);
            window.scrollBy(0,remainder);
        }
        var repeatCount = 0;
        var cTimeout;
        var timeoutIntervals = new Array();

        var timeoutIntervalSpeed;
        function ScrollSmoothly(scrollPos,repeatTimes)
        {
                if(repeatCount < repeatTimes)
                {
                window.scrollBy(0,50);
                }
                else
                {
                repeatCount = 0;
                clearTimeout(cTimeout);
                return;
                }
        repeatCount++;
        cTimeout = setTimeout("ScrollSmoothly('" + scrollPos + "','"+ repeatTimes +"')",10);
        }

example usage :

ScrollToControl('elementID');
it moves to the control smoothly;
