使用javascript開啟模態對話方塊

來源:互聯網
上載者:User

1. 標準的方法

<script type="text/javascript">  
function openWin(src, width, height, showScroll){  
window.showModalDialog (src,"","location:No;status:No;help:No;dialogWidth:"+width+";dialogHeight:"+height+";scroll:"+showScroll+";");  
}  
</script> 
例:<span style="CURSOR: pointer" onclick="openWin 
(’http://www.deepteach.com’, ’500px’, ’400px’, ’no’)">點擊</span> 

 

2. 要注意的是,Firefox並不支援該功能,它支援的文法是

window.open 
(’openwin.html’,'newWin’, 'modal=yes, width=200,height=200,resizable=no, scrollbars=no’ ); 

 

3. 如何自動判斷瀏覽器

<input type="button" value="開啟對話方塊" onclick="showDialog('#')"/> 
  <SCRIPT   LANGUAGE="JavaScript"> 
  <!-- 
  function   showDialog(url) 
  { 
   if(   document.all   ) //IE 
   { 
   feature="dialogWidth:300px;dialogHeight:200px;status:no;help:no"; 
   window.showModalDialog(url,null,feature); 
   } 
   else 
   { 
     //modelessDialog可以將modal換成dialog=yes 
   feature ="width=300,height=200,menubar=no,toolbar=no,location=no,"; 
   feature+="scrollbars=no,status=no,modal=yes";   
   window.open(url,null,feature); 
   } 
  } 
  //--> 
</SCRIPT>

 

4. 在IE中,模態對話方塊會隱藏地址欄,而在其他瀏覽器則不一定

 

【注意】在Google瀏覽器中,這個模態的效果也會失效。

 

 

5. 一般在彈出對話方塊的時候,我們都希望整個父頁面的背景變為一個半透明的顏色,讓使用者看到後面是不可以訪問的

而關閉對話方塊之後又希望還原

 

這是怎麼做到的呢?

        ///顯示某個訂單的詳細資料,通過一個模態對話方塊,而且螢幕會變顏色
        function ShowOrderDetails(orderId) {
            var url = "details.aspx?orderID=" + orderId;

//            $("body").css("filter", "Alpha(Opacity=20)");
            //filter:Alpha(Opacity=50)

            $("body").addClass("body1");

            ShowDetailsDialog(url, "600px", "400px", "yes");

            $("body").removeClass("body1");
        }

 

另外,有一個樣式表定義

.body1
{
    background-color:#999999;
    filter:Alpha(Opacity=40);
}

 

6. 如何在頁面之間傳遞數值

下面的部分,轉載自:http://www.cnblogs.com/tohen/archive/2007/12/15/995868.html

(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.

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

說明:
由於showModalDialog緩衝嚴重,下面是在子視窗取消用戶端緩衝的設定.也可以在伺服器端取消緩衝,參考:

<script language="javascript">
<!--
var k=window.dialogArguments;
//獲得父視窗傳遞來的值
if(k!=null)
        {
        document.getElementById("txt0").value = k.document.getElementById("txt9").value;
        }
//關閉視窗返回是否重新整理的參數.
function winClose(isRefrash)
        {
        window.returnValue=isRefrash;
        window.close();
        }
//-->
</script>
</BODY>
</HTML>

--------------------------
說明
1.下面是取消用戶端緩衝的:
<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衝,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.在子視窗中若要提交頁面的話要加入:,這樣就不會開啟新視窗了.
