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

        { 

         var  k  =  window.showModalDialog( " child.html " ,window, " dialogWidth:335px;status:no;dialogHeight:300px " ); 
         if (k  ==   1 ) // 判断是否刷新 
        { 
        alert('刷新'); 
        window.location.reload(); 
        } 
        } 
         // --> 
         </ script >
     </ HEAD >
     < BODY >
         < br >
        传递到父窗口的值: < input  id ="txt9"  type ="text"  value ="3333333333333"  NAME ="txt9" >< br >
         < input  type ="button"  value ="openChild"  onclick ="openChild()"  ID ="Button1"  NAME ="Button1" >

         // 获得父窗口传递来的值 
         if (k != null ) 
        { 
        document.getElementById( " txt0 " ).value  =  k.document.getElementById( " txt9 " ).value; 
        } 

         // 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>
