js实现上下滚动代码，网站常用代码，站长推荐学习。
复制代码代码如下：
- window.onload = function()
- {
- oMarquee = document.getElementById("mq"); // 滚动对象
- oMarquee.innerHTML += oMarquee.innerHTML;
-
- window.setTimeout("run()", 2000);
- }
-
- var oMarquee;
- var iScrollAmount = 1;
- function run()
- {
- oMarquee.scrollTop += iScrollAmount;
- if (oMarquee.scrollTop == oMarquee.firstChild.clientHeight)
- {
- oMarquee.scrollTop = 0;
- }
-
- if (oMarquee.scrollTop % 25 == 0) {
- window.setTimeout("run()", 2000);
- } else {
- window.setTimeout("run()", 50);
- }
- }
-
- </script>
