scrollAreal.direction='down';

Answer 1

当down的时候，滚动区域为何会向下去很多。

Answer 2

<table border="1" cellpadding="0" cellspacing="0" width="100%">
        <tr> 
          <td rowspan="3" align="right"><MARQUEE id=scrollArea1 scrollAmount=1 scrollDelay=60 direction=up width="90%" border="0" height="200">
            <table width="100%" align=center border=0 height="100">
              <% do while not down_ors.eof%>
              <tr> 
                <td width="250"><%=down_ors("downid").value %>、 <a href="<%=down_ors("downurl").value %>" target="_blank" title="<%=down_ors("downtime").value%>"><%=down_ors("downname").value %></a></td>
              </tr>
              <% down_ors.movenext
  loop  %>
            </table>
            </MARQUEE></td>
          <td align="right" width="12" height="12"><img src="images/scroll-up.gif"   onMouseOver="scrollArea1.direction='up';scrollArea1.start()" onMouseOut="scrollArea1.stop()"></td>
        </tr>
        <tr> 
          <td height="160">&nbsp;</td>
        </tr>
        <tr> 
          <td align="right" width="12" height="12" ><img src="images/scroll-dn.gif"  onMouseOver="scrollArea1.direction='down';scrollArea1.start()" onMouseOut="scrollArea1.stop()"></td>
        </tr>
      </table>
看看我这段代码有什么问题。当点down的时候，滚动区域为何会突然向下去很多。

大家看看这一页上的就知道了。在第一个滚动栏里，一碰down就下去很多了。
