仅仅一月的时间,曾经满眼雪白的棉花地只剩下暗褐色的一片,偶尔星星点点飘几点白色,也暗然无光。人类征服大自然的力量是神奇强大的,这种超乎寻常的功能有时候总让你难以置信。
本文实例讲述了JS实现的新闻列表自动滚动效果。分享给大家供大家参考,具体如下:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style type="text/css"> #box{width:260px;height:100px;margin:0 auto;border:2px solid red;overflow: hidden} ul{padding:0;margin:0;list-style: none;overflow: hidden} ul li{height:24px;line-height: 24px;padding-left:10px;} a{text-decoration: none;color:#000;} a:hover{color:#f00} </style> </head> <body> <div id="box"> <ul id="con1" onMouseOut="Up()" onMouseOver="Stop()"> <li><a rel="nofollow noopener noreferrer" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >1,课程html</a> </li> <li><a rel="nofollow noopener noreferrer" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >2,课程css</a> </li> <li><a rel="nofollow noopener noreferrer" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >3,课程js</a> </li> <li><a rel="nofollow noopener noreferrer" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >4,课程jquery</a> </li> <li><a rel="nofollow noopener noreferrer" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >5,课程html5</a> </li> <li><a rel="nofollow noopener noreferrer" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >6,课程css3</a> </li> <li><a rel="nofollow noopener noreferrer" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >7,课程hp</a> </li> <li><a rel="nofollow noopener noreferrer" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >8,课程bpootstrap</a> </li> <li><a rel="nofollow noopener noreferrer" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >9,课程apicloud</a> </li> </ul> <ul id="con2"></ul> </div> </body> <script type="text/javascript"> var box=document.getElementById("box"); var con1=document.getElementById("con1"); var con2=document.getElementById("con2"); var s=document.getElementsByTagName("a"); var speed=50; con2.innerHTML=con1.innerHTML; function ScrollUp(){ if( box.scrollTop>=con1.scrollHeight){ box.scrollTop=0; }else box.scrollTop++; } var i=setInterval("ScrollUp()",speed); function Stop(){ clearInterval(i); } function Up(){ i=setInterval("ScrollUp()",speed); } </script> </html>

本文JS实现的新闻列表自动滚动效果示例到此结束。一路上的行走,你是会遇上很多的人。也许是陪你走一站的,也许只是一个过客,于是生命中留下了许多逗号,一段经历一个逗号,一段感情一个逗号,一段付出一个逗号,无数个逗号的等待,也都只是为最终那个句号。小编再次感谢大家对我们的支持!
