用Jquery实现滚动新闻
此文主要用Jquery实现滚动新闻，如此少的代码就能实现这个功能真的是不由得感叹Jquery的强大功能。
代码如下：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script language="javascript" type="text/javascript">
$(function () {
var scrollTimer = null;
var delay = 2000;
//1.鼠标对新闻触发mouseout事件后每2s调用scrollNews()
//2.鼠标对新闻触发mouseover事件后停止调用scrollNews()
//3.初次加载页面触发鼠标对新闻的mouseout事件
$('div.scrollNews').hover(function () {
clearInterval(scrollTimer);
}, function () {
scrollTimer = setInterval(function () {
scrollNews();
}, delay);
}).triggerHandler('mouseout');
});
//滚动新闻
function scrollNews() {
var $news = $('div.scrollNews>ul');
var $lineHeight = $news.find('li:first').height();
$news.animate({ 'marginTop': -$lineHeight + 'px' }, 600, function () {
$news.css({ margin: 0 }).find('li:first').appendTo($news);
});
}
</script>
</head>
