缺少对象,ASP中的朋友说是JS错误,请高手指点

Question

<SCRIPT> 
  var speed=100 
  demo2.innerHTML=demo1.innerHTML 
  function Marquee(){ 
  if(demo2.offsetTop-demo.scrollTop <=0) 
  demo.scrollTop-=demo1.offsetHeight 
  else{ 
  demo.scrollTop++ 
  } 
  } 
  var MyMar=setInterval(Marquee,speed) 
  demo.onmouseover=function() {clearInterval(MyMar)} 
  demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)} 
  </SCRIPT>
顶

Answer 1

var MyMar=setInterval("Marquee()",speed) 
应该是这个地方的问题吧

Answer 2

下面这样可以实现，和你哪个差不多：
 <TABLE cellSpacing=0 cellPadding=0 width="96%" border=0>  
  <TBODY> 
  <TR>
    <TD> 
      <DIV id=demo style="OVERFLOW: hidden; WIDTH: 100%; COLOR: #ffffff"> 
      <TABLE cellSpacing=0 cellPadding=0 align=left border=0 cellspace="0"> 
        <TBODY> 
        <TR> 
          <TD id=demo1 vAlign=top><table width="1710" height="116"  border="0" cellpadding="0" cellspacing="0"> 
            <tr height=22 > 
              <td width="171"><div align="center">内容.....</div></td>               
            </tr> 
          </table></TD> 
          <TD id=demo2 vAlign=top> </TD></TR></TBODY></TABLE></DIV> 
      
    </TD></TR></TBODY></TABLE></TD></TR></TABLE> 
</CENTER><SCRIPT> 
var speed3=100//速度数值越大速度越慢 
var t=false; //判断是向左还是向右
document.getElementById("demo2").innerHTML=document.getElementById("demo1").innerHTML 
function Marquee(){ 
if(document.getElementById("demo2").offsetWidth-document.getElementById("demo").scrollLeft<=0) 
document.getElementById("demo").scrollLeft-=document.getElementById("demo1").offsetWidth 
else{ 
document.getElementById("demo").scrollLeft++ 
} 
t=false; 
} 
function RMarquee(){  
if(document.getElementById("demo").scrollLeft<=0) 
  document.getElementById("demo").scrollLeft+=document.getElementById("demo2").offsetWidth 
  else{ 
  document.getElementById("demo").scrollLeft-- 
  } 
  t=true; } 
var MyMar=setInterval(Marquee,speed3) 
document.getElementById("demo").onmouseover=function() {clearInterval(MyMar)} 
document.getElementById("demo").onmouseout=function() {if(t){MyMar=setInterval(RMarquee,speed3)}else{MyMar=setInterval(Marquee,speed3)}} 
</SCRIPT> 

Answer 3

问题主要发生在你的那个div要用td ，onmouseover 和 onmouseout事件没对象触发！

Answer 4

最好把你ASP解析后的表态页面源代码贴一下...

Answer 5

3楼的方法调试后还是出现缺少对象.
6楼的老韩,这部分文件的代码如下:
<td align="center" valign="top">
<table width="100%" border="0" cellspacing="0" cellpadding="0">
              <tr> 
                <td height="10"></td>

Answer 6

4楼的如风,我是菜鸟啊,具体如何修改啊?
5楼的无限,在ASP中多谢你的提点,对你的继续关注再次表示感谢~!!

Answer 7

这样吧，你把你这个代码解析为HTML后的代码复制上来
看看要不你用FF浏览查看，FF浏览器里有一个功能可以看你具体哪一句JS错误

Answer 8

<DIV id=demo style="OVERFLOW: hidden; COLOR: #ffffff; HEIGHT: 50px"> 
              <DIV id=demo1> 
                <TABLE cellSpacing=0 cellPadding=0 width="96%" border=0> 
                  <TBODY>                     <TR height=22 > 
                      <td align=left>fasdfasdf</td> 
  <td width=15> </td> 
                    </TR> <TR height=22 > 
                      <td align=left>fasdfasdf</td> 
  <td width=15> </td> 
                    </TR> <TR height=22 > 
                      <td align=left>fasdfasdf</td> 
  <td width=15> </td> 
                    </TR>                  </TBODY> 
                </TABLE> 
              </DIV> 
              <DIV id=demo2> </DIV> 
            </DIV> 
<SCRIPT> 
  var speed=100 
  demo2.innerHTML=demo1.innerHTML 
  function Marquee(){ 
  if(demo2.offsetTop-demo.scrollTop <=0) 
  demo.scrollTop-=demo1.offsetHeight 
  else{ 
  demo.scrollTop++ 
  } 
  } 
  var MyMar=setInterval(Marquee,speed) 
  demo.onmouseover=function() {clearInterval(MyMar)} 
  demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)} 
  </SCRIPT>
上面的没有问题
不过内容比较少也是一个问题，比如把HEIGHT: 设为500px  就运行不了了

Answer 9

你设置成500px，不行，是因为不满足条件，当然不会移动了，你把                    <TR height=22 > 
                      <td align=left>fasdfasdf </td> 
  <td width=15> </td> 
                    </TR> <TR height=22 > 
                      <td align=left>fasdfasdf </td> 
  <td width=15> </td> 
                    </TR> <TR height=22 > 
                      <td align=left>fasdfasdf </td> 
  <td width=15> </td> 
                    </TR> 多复制几个，在看看不就行了

Answer 10

不好意思，如何解析为HTML代码？？
