说明:
由于showModalDialog缓存严重,下面是在子窗口取消客户端缓存的设置.也可以在服务器端取消缓存,参考:

说明
1.下面是取消客户端缓存的:
<meta http-equiv="Expires" CONTENT="0">
<meta http-equiv="Cache-Control" CONTENT="no-cache">
<meta http-equiv="Pragma" CONTENT="no-cache">
也可以在服务器端取消缓存,参考:
http://adandelion.cnblogs.com/articles/252137.html
2.向父窗口传递阐述在ASP.NET中也可以是用aaa.aspx?id=1的方式传递.
3.不刷新父窗口的话在父窗口中直接这样一来设置可以.
<script>
window.showModalDialog("child.html",window,"dialogWidth:335px;status:no;dialogHeight:300px");
</script>
4.在子窗口中若要提交页面的话要加入:,这样就不会打开新窗口了.
<head>
<base target="_self">
</HEAD>
注：
父窗体向子窗体传值还可以这样：
window.showModalDialog("child.html?id=value1&id2=value2&......等",window,"dialogWidth:335px;status:no;dialogHeight:300px");
在子页面中用Request.QueryString["id"]来获取传值。
