经典的代码如下：

<table width=700 border=0 cellpadding=0 cellspacing=0>                                                                                                          
 <tr><td>                                                                                                                                                                                         
  <div id=demo style=overflow:hidden;height:120;width:700;color:#ffffff><table align=left cellpadding=0 cellspace=0 border=0><tr><td id=demo1 valign=top>
  <table border=0 cellpadding=0 cellspacing=0>
  <tr><td><a href=# target=_blank><img src=jsimg/1.jpg width=150 height=100  class=b5 hspace=22></a><br><center><b>说明一</b></center></td>
  <td width=30></td>
  <td><a href=# target=_blank><img src=jsimg/2.jpg width=150 height=100  class=b5 hspace=22></a><br><center><b>说明二</b></center></td></td>
  <td width=30></td>
  <td><a href=# target=_blank><img src=jsimg/3.jpg width=150 height=100  class=b5 hspace=22></a><br><center><b>说明三</b></center></td>
  <td><a href=# target=_blank><img src=jsimg/4.jpg width=150 height=100  class=b5 hspace=22></a><br><center><b>说明四</b></center></td>
  <td width=30></td>
  <td><a href=# target=_blank><img src=jsimg/5.jpg width=150 height=100  class=b5 hspace=22></a><br><center><b>说明五</b></center></td>
  </tr>
  </table>
 </td><td id=demo2 valign=top></td></tr></table></div>
  <script>
  var speed=10//速度数值越大速度越慢
  demo2.innerHTML=demo1.innerHTML
  function Marquee(){
  if(demo2.offsetWidth-demo.scrollLeft<=0)
  demo.scrollLeft-=demo1.offsetWidth
  else{
  demo.scrollLeft++
  }
  }
  var MyMar=setInterval(Marquee,speed)
