showModalDialog 傳值及重新整理

(一)showModalDialog使用例子,父視窗向子視窗傳遞值,子視窗設定父視窗的值,子視窗關閉的時候傳回值到父視窗.

說明:

由于showModalDialog緩存嚴重,下面是在子視窗取消用戶端緩存的設定.也可以在伺服器端取消緩存,參考:

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)下面是關閉重新整理父視窗的例子

         < script  language ="javascript" >  

         <!--  

         function  openChild() 

        { 

         var  k  =  window.showModalDialog( " child.html " ,window, " dialogWidth:335px;status:no;dialogHeight:300px " ); 

         if (k  ==   1 ) // 判斷是否重新整理 

        { 

        alert('重新整理'); 

        window.location.reload(); 

        } 

        } 

         // --> 

         </ script >

     </ HEAD >

     < BODY >

         < br >

        傳遞到父視窗的值: < input  id ="txt9"  type ="text"  value ="3333333333333"  NAME ="txt9" >< br >

         < input  type ="button"  value ="openChild"  onclick ="openChild()"  ID ="Button1"  NAME ="Button1" >

        } 

         // 關閉視窗傳回是否重新整理的參數. 

         function  winClose(isRefrash) 

        { 

        window.returnValue = isRefrash; 

        window.close(); 

        } 

         // -->

說明

1.下面是取消用戶端緩存的:

<meta http-equiv="Expires" CONTENT="0">

<meta http-equiv="Cache-Control" CONTENT="no-cache">

<meta http-equiv="Pragma" CONTENT="no-cache">

也可以在伺服器端取消緩存,參考:

http://adandelion.cnblogs.com/articles/252137.html

2.向父視窗傳遞闡述在ASP.NET中也可以是用aaa.aspx?id=1的方式傳遞.

3.不重新整理父視窗的話在父視窗中直接這樣一來設定可以.

<script>

window.showModalDialog("child.html",window,"dialogWidth:335px;status:no;dialogHeight:300px");

</script>

4.在子視窗中若要送出頁面的話要加入:,這樣就不會打開新視窗了.

<head>

<base target="_self">

</HEAD>
