Today I will share a jquery to achieve multi-line scrolling effect.

I saw that on some forum websites, announcements are often used.

The code is as follows

// 多行滚动
(function($){
$.fn.extend({
Scroll:function(opt,callback){
if(!opt) var opt={};
var _this=this.eq(0).find("ul:first");
var lineH=_this.find("li:first").height(),
line=opt.line?parseInt(opt.line,10):parseInt(this.height()/lineH,10),
speed=opt.speed?parseInt(opt.speed,10):1000, //卷动速度,数值越大,速度越慢(毫秒)
timer=opt.timer?parseInt(opt.timer,10):5000; //滚动的时间间隔(毫秒)
if(line==0) line=1;
var upHeight=0-line*lineH;
scrollUp=function(){
_this.animate({
marginTop:upHeight
},speed,function(){
for(i=1;i

The code is as follows

<div id="scrollDiv">
<ul>
<li>我是jquery多行滚动条一</li>
<li>我是jquery多行滚动条二</li>
<li>我是jquery多行滚动条三</li>
<li>我是jquery多行滚动条四</li>
<li>我是jquery多行滚动条五</li>
<li>我是jquery多行滚动条六</li>
<li>我是jquery多行滚动条七</li>
<li>我是jquery多行滚动条八</li>
</ul>
</div>
