子窗口父窗口传递

Question

我想先做个网页为index.asp
页面上有个链接点击后出现一个小窗口aaa.asp
aaa.asp上是一个表单
如果在表单中输入123
确定后子窗口aaa.asp关闭
父窗口index.asp重新定向为index.asp?id=123===========================================
index.asp
===========================================
<a href="javascript:void(window.dialog=open("aaa.asp","__dialog","width=;height=;..."));" target="_self">open</a>===========================================
aaa.asp
===========================================
<form action="javascript:void(window.opener.location.href="index.asp?id="+sid.value;window.opener=null;window.close();return false;);"><input type="text" name="sid" id="sid"><input type="submit"></form>
