100分求助C#加javascript做动态菜单问题
我做的这个菜单无法拉下和收起，数据都能显示出来的。请哪位大人帮我看看，谢谢了

代码如下：
//javascript--显示和隐藏下拉框的代码
string st= " <script language= 'javascript '> ";
st+= " '  ";

//这里是对数据进行读取
st= " <tabel borderColor= 'lightskyblue ' cellSpacing= '0 ' cellPadding= '0 ' width= '100 ' border= '1 'align= 'center '> ";
string str= "select distinct(class) from club_class ";
DataSet ds=SqlDB.GetDataSet(str);

for(int i=0;i <ds.Tables[0].Rows.Count;i++)
{
if(ds.Tables[0].Rows[i][0].ToString()!= " ")
{
string str1= "select top 5 title from club_main where class= ' "+ds.Tables[0].Rows[i][0].ToString()+ " ' ";
DataSet ds1=SqlDB.GetDataSet(str1);

//主菜单
st+= " <tr> <td align= 'left ' onclick= 'menuclick(submenu "+i+ ",bar "+i+ " ); ' style= 'CURSOR:hand ' width= '103 ' ";

st+= "bordercolordark= 'white ' bordercolorlight= 'gray ' onmouseover= 'this.style.backgroundColor= '#FFCCCC ' ";

st+= "onmouseout= 'this.style.backgroundColor= ' ' ' title= '主题列表 '> ";
st+= " <img src= '../admin/plus.gif ' border= '0 ' id= 'bar "+i+ " ' width= '11 ' height= '11 '> <font color= '#000000 '> ";
st+= " "+ds.Tables[0].Rows[i][0].ToString()+ " </font> ";

//下拉菜单
st+= " <tr> <td align= 'left ' width= '143 '> <span id= 'submenu "+i+ " ' style= 'DISPLAY:block;MARGIN-LEFT:5px '> ";
for(int j=0;j <ds1.Tables[0].Rows.Count;j++)
{
if(ds1.Tables[0].Rows[j][0].ToString().Length> 12)
{
ds1.Tables[0].Rows[j][0]=ds1.Tables[0].Rows[j][0].ToString().Substring(0,12)+ ".. ";
}
else
{
ds1.Tables[0].Rows[j][0]=ds1.Tables[0].Rows[j][0].ToString();
}
st+= " <img src= '../user/images/index_point.gif ' border= '0 ' width= '12 ' height= '12 '> "+ds1.Tables[0].Rows[j][0].ToString()+ " <br> ";
}

st+= " </td> </tr> ";
}

}
st+= " </tabel> ";
Label1.Text=st.ToString()；

运行后IE状态提示：网页上有错误

运行后源代码如下：
<TABLE id= "Table10 " cellSpacing= "1 " cellPadding= "1 " width= "150 " align= "center " border= "0 ">
<TBODY>
<TR>
<TD>
<span id= "Label1 ">
<tabel borderColor= 'lightskyblue ' cellSpacing= '0 ' cellPadding= '0 ' width= '100 ' border= '1 'align= 'center '>
<tr>

</tr>

<font color= '#000000 '> 配方切磋 </font>

</TR>
</TABLE>

[解决办法]
对了：把第2行
st+= " ' <!-- ' ";
改为
st+= " '// <!-- ' ";

俺直接新建了一个这样的html，直接用浏览器打开可以
<script language= 'javascript '>
// <!--
var old_menu = ' ';

st+= "submenu.style.display = 'block '; cellbar.src = 'plus.gif '; old_menu = submenu; old_cell = cellbar; } ";
st+= "else{ submenu.style.display = 'none '; cellbar.src= 'plus.gif '; old_menu = ' '; old_cell = ' '; } ";
st+= "} ' "; --单引号
st+= "//--> ";---没有 </script>
