好了，给你个例子吧，自己改一下就可以了！！
第一种方案是：
file a.htm
function OpenDialog(url,param)
{
return window.open(url,param, "DialogWidth:450px;DialogHeight:450px;help:no;status:no");
}
file b.htm
1<script language="javascript">
2function js_do(val)
3{
4self.opener.document.all.filename.value=val
5}
6</script>
第二种方案是：
file A.htm
1<html>
2<script language="javascript">
3function OpenDialog(url,param)
4{
5return window.showModalDialog(url,param, "DialogWidth:450px;DialogHeight:450px;help:no;status:no");
6}
7
8function js_getData(url)
9{
10return OpenDialog("b.htm","");
11}
12
13</script>
14<body>
15<form name="myFrm">
16<input name="filename" onclick="this.value=js_getData()" type="text"/>
17</form>
18</body>
19</html>
file b.htm
1<html>
2<script language="javascript">
3function js_do(val)
4{
5window.returnValue=val;
6window.close();
7}
8</script>
9<body>
10<form name="myFrm">
11<input name="filename" type="text"/>
12<input name="btnDo" onclick="js_do(this.form.filename.value)" type="text"/>
13</form>
14</body>
15</html>
Response.Write("
1<script language="javascript">window.opener.document.all.txt1.value="+theValue+";</script>
");
