参数传递问题
我最近在做一个跑马灯代码   要把它封装起来   但是在参数传递的时候却怎么都不行。
没有参数传递的代码:
<html>
<head>
<title> 左右滚动的图片效果   -   51windows.Net </title>
<meta   http-equiv= "Content-Type "   content= "text/html;   charset=gb2312 ">
</head>
<body   bgcolor= "#999999 ">

<table   border= "1 "   width= "760 "   align= "center ">
    <tr>
        <td   width= "215 ">   </td>
        <td   width= "545 ">
<!--   滚动代码   begin   -->
<div   id= "demo "   style= "overflow:hidden;height:120px;width:543px; ">
<table   width= "100% "   cellspacing= "0 ">
<tr>
<td   id= "demo1 ">
<table   cellspacing= "0 "   cellspacing= "2 ">
<tr>
<td> <a   href= "http://www.51windows.net/mypic/sight/page_01.htm "   target= "_blank "> <img   src= "http://www.51windows.net/51wfolder_1/jsimg/TN_Feng016.JPG "   border= "0 "/> </a> </td>
<td> <a   href= "http://www.51windows.net/mypic/sight/page_01.htm "   target= "_blank "> <img   src= "http://www.51windows.net/51wfolder_1/jsimg/TN_Feng017.JPG "   border= "0 "/> </a> </td>
<td> <a   href= "http://www.51windows.net/mypic/sight/page_01.htm "   target= "_blank "> <img   src= "http://www.51windows.net/51wfolder_1/jsimg/TN_Feng018.JPG "   border= "0 "/> </a> </td>
<td> <a   href= "http://www.51windows.net/mypic/sight/page_01.htm "   target= "_blank "> <img   src= "http://www.51windows.net/51wfolder_1/jsimg/TN_Feng019.JPG "   border= "0 "/> </a> </td>
<td> <a   href= "http://www.51windows.net/mypic/sight/page_01.htm "   target= "_blank "> <img   src= "http://www.51windows.net/51wfolder_1/jsimg/TN_Feng020.JPG "   border= "0 "/> </a> </td>
<td> <a   href= "http://www.51windows.net/mypic/sight/page_01.htm "   target= "_blank "> <img   src= "http://www.51windows.net/51wfolder_1/jsimg/TN_Feng021.JPG "   border= "0 "/> </a> </td>
</tr>
</table>
</td>
<td   id= "demo2 "> </td>
</tr>
</table>
</div>
<!--   滚动代码   end   -->
</td>
    </tr>
</table>
<script>
var   speed=50
demo2.innerHTML=demo1.innerHTML
function   Marquee(){if(demo2.offsetWidth-demo.scrollLeft <=0){demo.scrollLeft-=demo1.offsetWidth;}else{demo.scrollLeft+=2}}
var   MyMar=setInterval(Marquee,speed)
demo.onmouseover=function()   {clearInterval(MyMar)}
demo.onmouseout=function()   {MyMar=setInterval(Marquee,speed)}
</script>
</body>
</html>
这个代码没有问题   可以运行  
带参数传递的代码   。
<html>
<head>
