A nice multi line text image scrolling effect implemented by jquery

Today we share a jquery implementation for multi-line scrolling.

I see some forum website above, bulletin board USES more.

The following code

//Multi-line rolling
(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, //Scroll speed, the larger the value, the slower the speed (millisecond)
timer=opt.timer?parseInt(opt.timer,10):5000; //Time interval for scrolling (milliseconds)
if(line==0) line=1;
var upHeight=0-line*lineH;
scrollUp=function(){
_this.animate({
marginTop:upHeight
},speed,function(){
for(i=1;i

Examples demonstrate

The following code

<div id="scrollDiv">
<ul>
<li> I am a jquery Multi-line scrollbar one </li>
<li> I am a jquery Multi-line scrollbar two </li>
<li> I am a jquery Multi-line scrollbar three </li>
<li> I am a jquery Multi-line scrollbar 4 </li>
<li> I am a jquery Multi-line scrollbar 5 </li>
<li> I am a jquery Multi-line scroll bar six </li>
<li> I am a jquery Multi-line scrollbar seven </li>
<li> I am a jquery Multi-line scrollbar 8 </li>
</ul>
</div>
