这个JS 如何在一个页面实现两次

<script language="javascript" type="text/javascript">

Answer 1

var Speed = 0.08; //速度(毫秒)
var Space = 5; //每次移动(px)
var PageWidth = 160; //翻页宽度
var fill = 0; //整体移位
var MoveLock = false;
var MoveTimeObj;
var Comp = 0;
var AutoPlayObj = null;
GetObj("List2").innerHTML = GetObj("List1").innerHTML;
GetObj('ISL_Cont').scrollLeft = fill;
GetObj("ISL_Cont").onmouseover = function(){clearInterval(AutoPlayObj);}
GetObj("ISL_Cont").onmouseout = function(){AutoPlay();}
AutoPlay();
封装成一个函数，在需要调用其他函数地方之前先调用下这个函数

Answer 2

var Speed2 = 0.08; //速度(毫秒)
var Space2 = 5; //每次移动(px)
var PageWidth2 = 160; //翻页宽度
var fill2 = 0; //整体移位
var MoveLock2 = false;
var MoveTimeObj2;
var Comp2 = 0;
var AutoPlayObj2 = null;
各种2 .....最好还是封装下。。。给函数都带上参数 ...

Answer 3

这里有一个无缝滚动效果
方向可以自己设置
可以设置定高定宽停顿
你把文字改成图片就行
里面有源码可以参考
