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.

說明:

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.
