---------------------------- 
說明: 
因爲showModalDialog緩存嚴重,下面是在子窗口取消客戶端緩存的設置.也能夠在服務器端取消緩存,參考:

(二)下面是關閉刷新父窗口的例子

 { 
  alert('刷新'); 
  window.location.reload(); 
 } 
}

<BODY> 
<br>傳遞到父窗口的值:<input id="txt9" type="text" value="3333333333333"><br>

<br>父窗口傳遞來的值:<input id="txt0" type="text"><br>

<input type ="button" value="關閉刷新父窗口" onclick="winClose(1)"> 
<input type ="button" value="關閉不刷新父窗口" onclick="winClose(0)">

</BODY> 
</HTML>

<script language=javascript> 
<!-- 
var k=window.dialogArguments; 
//得到父窗口傳遞來的值 
if(k!=null) 
 { 
 document.getElementById("txt0").value = k.document.getElementById("txt9").value; 
 }

//關閉窗口返回是否刷新的參數. 
function winClose(isRefrash) 
{

window.returnValue=isRefrash; 
window.close(); 
} 
//--> 
</script>

-------------------------- 
說明 
1.下面是取消客戶端緩存的: 
<meta http-equiv="Expires" CONTENT="0"> 
<meta http-equiv="Cache-Control" CONTENT="no-cache"> 
<meta http-equiv="Pragma" CONTENT="no-cache"> 
也能夠在服務器端取消緩存,參考: 
http://adandelion.cnblogs.com/articles/252137.html

2.向父窗口傳遞闡述在ASP.NET中也能夠是用aaa.aspx?id=1的方式傳遞. 

3.不刷新父窗口的話在父窗口中直接這樣一來設置能夠. 
<script> 
window.showModalDialog("child.html",window,"dialogWidth:335px;status:no;dialogHeight:300px"); 
</script> 
4.在子窗口中若要提交頁面的話要加入:,這樣就不會打開新窗口了.
<head>
<base target="_self">
</HEAD>
