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:
http://adandelion.cnblogs.com/articles/252137.html
<meta http-equiv="Expires" CONTENT="0">
<meta http-equiv="Cache-Control" CONTENT="no-cache">
<meta http-equiv="Pragma" CONTENT="no-cache">



(二)下面是关闭刷新父窗口的例子

        } 

        //关闭窗口返回是否刷新的参数. 
        function winClose(isRefrash) 
        { 
        window.returnValue=isRefrash; 
        window.close(); 
        } 
        //--> 
        </script>
    </BODY>
</HTML>

--------------------------
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>
