Various JQuery loop scrolling text and picture effect codes

I imitated the writing method of JQ plug-in and wrote a circular scrolling list plug-in, which supports customization of the four directions of up, down, left, and right, and supports smooth scrolling or intermittent scrolling, both of which are set through parameters. There are some repetitive parts in JQ, and I can't think of a better way to streamline them yet. However, the effect is still good, as follows (the renderings are accelerated after uploading, and the actual effect is much slower than this):

The html code is as follows:

<!doctype html>
<html lang="zh-cn">
<head>
<meta charset="utf-8">
<title>循环滚动列表</title>
<link href="css/style.css" rel="stylesheet"/>
<script src="js/jquery-1.9.1.min.js"></script>
<script src="js/autoScroll.js"></script>
<script>
 $(function(){
 //下面是调用语句，以ID名区分

 $("#autoScroll01").autoScroll({
  direction: 'left',    //滚动方向，'up'、'down'、'left'、'right'，*必须参数
  interval: 40,      //滚动间隔，单位'ms'，一定要大于'滚动速度'，*必须参数
  speed: 10,      //滚动完成耗时，单位'ms'，一定要小于'滚动间隔'，*必须参数
  distance: 3,      //单次滚动距离，单位'px'，*必须参数  
  liWidth: 144,      //单个li的盒模型高度&宽度(包括margin值。左右滚动只有liWidth参数，上下滚动只有liHeight参数)，*必须参数
  showNum: 6      //显示几个li，父级高会自适应，但不要超过最大个数，*必须参数 
 });

 $("#autoScroll02").autoScroll({
  direction: 'up',     
  interval: 50,      //interval、speed、distance都很小时，就形成了平滑滚动现象。
  speed: 10,      
  distance: 1,      
  liHeight: 30,          
  showNum: 4      
 });

 $("#autoScroll03").autoScroll({
  direction: 'down',    //向下滚动
  interval: 2000,     //2秒滚动一次
  speed: 600,      //滚动耗时0.6秒（所以必须2秒内滚完，以免没滚完就执行下一次滚动了）
  distance: 40,     //一次滚动40px
  liHeight: 40,     //单个的li的盒模型高度是40px（上下滚动li没有margin跟padding值）
  showNum: 3      //容器里显示3个li标签
 });

 $("#autoScroll04").autoScroll({
  direction: 'right',
  interval: 2500,     //interval、speed、distance都很大时，就形成了间歇性滚动现象。
  speed: 800,
  distance: 288,     
  liWidth: 144,     //左右滚动时，liWidth要算上margin值，注意盒模型
  showNum: 5     
 });

 });
