javascript showModalDialog模態(tài)對話框使用說明

更新時間：2009年12月31日 22:34:19 作者：

使用javascript打開模態(tài)對話框，想學(xué)習(xí)showModalDialog使用方法的朋友可以參考下。

1. 標(biāo)準(zhǔn)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://m.fzitv.net', '500px', '400px', 'no')">點擊</span>

2. 要注意的是，F(xiàn)irefox并不支持該功能，它支持的語法是

復(fù)制代碼代碼如下:

 
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

復(fù)制代碼代碼如下:

 
<input type="button" value="打開對話框" 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(tài)對話框會隱藏地址欄，而在其他瀏覽器則不一定

【注意】在谷歌瀏覽器中，這個模態(tài)的效果也會失效。

5. 一般在彈出對話框的時候，我們都希望整個父頁面的背景變?yōu)橐粋€半透明的顏色，讓用戶看到后面是不可以訪問的

而關(guān)閉對話框之后又希望還原

這是怎么做到的呢？

復(fù)制代碼代碼如下:

 
///顯示某個訂單的詳細(xì)信息，通過一個模態(tài)對話框，而且屏幕會變顏色 
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

復(fù)制代碼代碼如下:

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

6. 如何在頁面之間傳遞數(shù)值
showModalDialog 傳值及刷新
(一)showModalDialog使用例子,父窗口向子窗口傳遞值,子窗口設(shè)置父窗口的值,子窗口關(guān)閉的時候返回值到父窗口.

說明:
由于showModalDialog緩存嚴(yán)重,下面是在子窗口取消客戶端緩存的設(shè)置.也可以在服務(wù)器端取消緩存,參考:

//關(guān)閉窗口返回是否刷新的參數(shù). 
function winClose(isRefrash) 
{ 
window.returnValue=isRefrash; 
window.close();

</script> 
</BODY> 
</HTML> 

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">
也可以在服務(wù)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中也可以是用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(shè)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頁面的話要加入:,這樣就不會打開新窗口了.
<head>
<base target="_self">
</HEAD>
