javascript从来没写过，求一个定制浮动广告的简单代码(MM)！
以下代码是3个漂浮的图片代码..........如何修改能够自己定制图片显示的数量？
<script language="javascript">

加一個就是:
function pagestart()
{checkbrOK();
chip1=new Chip("chip1",60,80);
chip2=new Chip("chip2",150,180);
chip3=new Chip("chip3",50,100);
chip4=new Chip("chip4",50,100);
if(brOK)
{
movechip("chip1");
movechip("chip2");
movechip("chip3")
movechip("chip4")
}
<DIV id="chip4"
style="height: 105; position: absolute; visibility: visible; width: 140; left: 180; top: 157">
<TABLE border=0 cellPadding=4 cellSpacing=0 class=bd width=60 ID="Table4">
<TBODY>
<TR>
<TD align=middle class=bg2><A class=prs1
href="http://" target=_blank><IMG border=0 class=bd src="样品.jpg" width="283" height="212"></A></TD></TR></TBODY></TABLE><SCRIPT event=onload for=window language=JavaScript>
pagestart();
</SCRIPT></DIV>Top

我得意思是自己定制，比如在pagestart(num) 加一个参数，num就是图片的数量，然后根据num的值来实例化chip.............帮帮忙！！！Top

function pagestart()
{checkbrOK();
chip1=new Chip("chip1",60,80);
chip2=new Chip("chip2",150,180);
chip3=new Chip("chip3",50,100);
if(brOK)
{
movechip("chip1");
movechip("chip2");
movechip("chip3")
}
}
这个函数把他改一下就行了Top

你可以在pagestart(num)然后循环取得chipTop

我就是不知道怎么循环实例化Top
