js上下文字滚动代码
就是每隔几秒，文字向上滚动，纯js实现的。一般用来做新闻啊或者公告啥的，很常用，记下来，反正自己也写不出来。:(<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
.llx-announce #div2 {
height: 22px;
overflow: hidden;
}
.llx-announce a {
overflow: auto;
display: block;
line-height: 22px;
text-decoration: none;
}
</style>
</head>
<body>
<div class="llx-announce">
<div id="div2">
<a href="#">这是标题一</a>
<a href="#">这是标题二</a>
<a href="#">这是标题三</a>
</div>
</div>
<script>
var box = document.getElementById("div2"), can = true;
box.innerHTML += box.innerHTML;
box.onmouseover = function () {
can = false
};
box.onmouseout = function () {
can = true
};
new function () {
var stop = box.scrollTop % 22 == 0 && !can;
if (!stop) box.scrollTop == parseInt(box.scrollHeight / 2) ? box.scrollTop = 0 : box.scrollTop++;
setTimeout(arguments.callee, box.scrollTop % 22 ? 10 : 3000);
};
</script>
</body>
</html>
