ie和firefox中的js区别

小弟现有一段js代码，在ie中可以正常使用，但是到ff中就不能，望指教！
代码如下：
<script type="text/JavaScript">
function showsubmenu(sid)
{
whichEl = eval("submenu" + sid);
imgmenu = eval("imgmenu" + sid);
if (whichEl.style.display == "none")
{
eval("submenu" + sid + ".style.display=\"\";");
imgmenu.background="images/bg_nav1.gif";
imgmenu.className='whi12B';
}
else
{
eval("submenu" + sid + ".style.display=\"none\";");
imgmenu.background="images/bg_nav.gif";
imgmenu.className='blu12B';
}
}
</script>

<table width="200" border="0" cellspacing="0" cellpadding="0">
      <tr>
         <td height="30"></td>
      </tr>
      <tr>
         <td height="34" valign="bottom" background="images/bg_nav.gif" id="imgmenu0" style="cursor:hand" onClick="showsubmenu(0)" class="blu12B" onmouseover="showbg(0)" onmouseout="hidbg(0)"><div style="margin-left:34px; margin-bottom:13px">aaaaaaa</div></td>
      </tr>
      <tr>
         <td id="submenu0" style="DISPLAY: none"><table width="200" border="0" cellpadding="0" cellspacing="0">
            <tr>
               <td width="34" height="21" align="right" background="../images/bg_nav.gif"><img src="../images/btm_tubiao7.gif" width="2" height="3" hspace="5" /></td>
               <td width="166" align="left" valign="middle" background="../images/bg_nav.gif"><a href="11.htm" class="blk10" id="subitem1">11</a></td>
            </tr>
            <tr>
               <td height="1" colspan="2" align="left" valign="top" background="../images/img_line1.gif"></td>
            </tr>
            <tr>
               <td height="21" align="right" background="../images/bg_nav.gif"><img src="../images/btm_tubiao7.gif" width="2" height="3" hspace="5" /></td>
               <td align="left" valign="middle" background="../images/bg_nav.gif"><a href="22.htm" class="blk10" id="subitem2">22</a></td>
            </tr>
            <tr>
               <td height="1" colspan="2" align="left" valign="top" background="../images/img_line1.gif"></td>
            </tr>
         </table></td>
      </tr>
      </table>

element的对象，在ie下可以直接用document.elementName访问
在ff下，必须用document.getElementById(elementId)来获取（ie下也可如此）

imgmenu.background="images/bg_nav.gif";
imgmenu.className='blu12B'

html 元素中怎么没看到有 id=imgmenu 的元素? 只有 id=imgmenu0

你这样 ie中应该也用不了啊
