var scrollContWidth = 230; //滚动区域的宽度
var scrollSpeed = 25; //滚动的速度，越小滚动越快
var scrollContainer = document.getElementById("scrollContainer");
var scrollContent = document.getElementById("scrollContent");
do
{
scrollContainer.appendChild(scrollContent.cloneNode(true));
}while(scrollContainer.offsetHeight < scrollContHeight);
scrollContainer.style.width = scrollContWidth+"px";
scrollContainer.style.height = scrollContHeight+"px";
scrollContainer.noWrap = true;
//添加事件：鼠标经过，停止滚动；鼠标离开，继续滚动
scrollContainer.onmouseover = new Function("stopscroll = true");
scrollContainer.onmouseout = new Function("stopscroll = false");
function init()
{
scrollContainer.scrollTop = 0;
setInterval(scrollUp,scrollSpeed);
}
init();
var currTop = 0;
function scrollUp()
{
if(stopscroll == true)
return;
currTop = scrollContainer.scrollTop;
scrollContainer.scrollTop += 1;
if(currTop == scrollContainer.scrollTop)
{
scrollContainer.scrollTop = 0;
scrollContainer.scrollTop += 1;
}
}
