直接用.net数据控件组合也没有问题的~~
{
if(document.getElementById(id).style.display=="block")
{
document.getElementById(id).style.display="none";
obj.src="Images/jia.gif";
}
else
{
document.getElementById(id).style.display="block";
obj.src="Images/jian.gif";
}
}
在TABLE里面写
<td style="width: 324px" align="left">
<img src="Images/jia.gif" alt="" onclick="selReply(this,'<%# Eval("ID") %>')" /><%# Eval("Subject") %>
</td>

这个应该可以满足你.
