想在调用模态窗口时传递参数，但是没成功，高手教我！！

window.showModalDialog('CellsTreeOfUser.aspx?UserID=' + userid, window, "");

to net_lover(孟子E章) ：我用了你教的方法，但还是不行，报同样的错误。我把 lblUserID.visible=False (隐藏了)，document.getElementById("lblUserID").innerText这于上面语句的执行有什么关系吗？？？

没有id="lblUserID"的对象。
请注意大小写

lblUserID.visible=False以上这一句话不正确，False不等于false，怎么可能执行的过去?可以用以下句子：lblUserID.style.visibility="hidden"
lblUserID.style.display="none"
--------------------可不可以把源文件贴出来看一看

楼上的大哥误解了我的意思，我的项目是在ASP.net 中开发的，以上写的Javascript是嵌在Html中的。我说的lblUserID.visible=False 是VB中的写法，我看过运行时页面的源代码，其中没有lblUserID 这个控件，在.net 中控件置为False后，在运行时页面的源代码中就不会出现该控件，我想问这是否对我写的Javascript有影响？

这是运行时页面的源代码：<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

那有什么办法可以补救一下的（lblUserID肯定是不会出现在源代码中的）

function ShowCellsTree()
{
var userid="";
if(document.getElementById("lblUserID")!=null)
userid=document.getElementById("lblUserID").innerText;
window.showModalDialog('CellsTreeOfUser.aspx?UserID=' + userid,window);
}
