给你个简单示例：
//main.asp
function show_dialog2(src,viewtype)
{
//向dialog中传入单个参数
// var dialogArg="src"
//向dialog中传入一个数组参数
var dialogArg=new Array();
var the_url = "";
var the_winstate="";
var str;
str="dialogArg[0]=frm."+src+".value";
eval(str);
dialogArg[1]=viewtype;
the_url="editinfo.asp"; //定义dialog窗的页面ＵＲＬ
the_winstate="dialogWidth:500px;dialogHeight:400px;status:'no'";　　//定义页面的大小风格
var result=showModalDialog(the_url,dialogArg,the_winstate);
if(typeof(result)!="undefined")
{
str="frm."+src+".value=result";
eval(str);　　
}
}///editinfo.asp
<textarea rows="20" cols="60" name="data" readonly>
//从页面中取得一个参数
//document.all("data").value=window.dialogArguments;
//从页面中取得数组参数
document.all("data").value=window.dialogArguments[0];
if(window.dialogArguments[1]=="edit")
{
document.all.data.readOnly=false;
}
else
{
document.all.save.style.display="none";
}
function checkdata()
{
var content=document.all("data").value
var len=CheckStrLen(content);
if(len>=2000)
{
alert("内容不能超过2000字节！")
}
else
{
//returnValue在页面中不能定义，否则返回undefined
returnValue=content; //赋返回值
window.close(); //关窗口
}
}
</script>

已解决还有一个问题。就是这里CSDN里面的见：http://www.csdn.net/Develop/Add_Article.asp
假如我“发表了文章”后，在里面的add_sql.asp里面request，怎么样才能得到那个编辑框里面的内容呢？？谢谢

<OBJECT id=doc_html style="LEFT: 0px; TOP: 0px" data="Editor.htm" idth=544 height=320 type="text/x-scriptlet" VIEWASTEXT></OBJECT>
关键是这里。。我不知道怎么得到一个控件里面的内容。。

看js代码，里面应该定义了变量，类似textarea.value之类的

注意：Editor.htm里的内容和id=doc_html

或者 .Text
呵呵，我也迷惑啦

根本就没有textarea,怎么回事？

我是使用iframe实现的，代码如下：
编辑页面：
<iframe class="Composition" ID="Composition" MARGINHEIGHT="1" MARGINWIDTH="1" width="100%" height="400" oncontextmenu="return false" scrolling="1">
下面的代码是在Composition所在页面开的一个新窗口：

<script language=javascript>
str='<IMG alt="" src="'+'<%=tempfilename%>'+'" align=baseline border=0>';
//InitDocument();
//alert(str);
/*
将str直接加入到框架iframe的内容( opener.Composition.document.body.innerHTML)中会对str中的字串进行server.htmlencode操作，所以可以采用下面的方面将框架内容和str中的内容合并。 */
opener.parent.form1.content.value=opener.Composition.document.body.innerHTML+str;
//alert(opener.parent.form1.content.value);
opener.Composition.document.body.innerHTML=opener.parent.form1.content.value;
window.close();
opener.window.focus();
</script>我猜想你那里可以试试：
doc_html.innerhtml
应该可以取到编辑内容。

模式对话框里传值不是那么传的~在打开模式对话框之前先要将dialogArguments属性赋值，这个就是你要传的值window.dialogArguments = 5在showModalDialog("","这里这个变量是将来引用的时候的变量名，这样在对话框中就可以引用到该值了~","")

晕倒，不对哈，我说的不对哈~^^应该是这样的~dialogProperty1="dialogWidth:500px; dialogHeight:200px; center:yes"
var newMenuItem=new Array()
newMenuItem[0]=0
newMenuItem[1]=menuOne
retval = window.showModalDialog("/ltiface.nsf/addMenuItem?openform",newMenuItem,dialogProperty1);通过window.dialogArguments访问传入的参数。

应该是这个样子的咯~aaa.htm（父窗口）<script>
var ss = showModalDialog("dia.htm","test");
</script>dia.htm（对话框）<script>
alert(window.dialogArguments);
</script>
