使用javascript打开模态对话框,想学习showModalDialog使用方法的朋友可以参考下。
1. 标准的方法
复制代码 代码如下:
<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.jb51.net', '500px', '400px', 'no')">点击</span> 
2. 要注意的是,Firefox并不支持该功能,它支持的语法是  
复制代码 代码如下:
window.open 
('openwin.html','newWin', 'modal=yes, width=200,height=200,resizable=no, scrollbars=no' );  
3. 如何自动判断浏览器
复制代码 代码如下:
<input type="button" value="打开对话框" 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可以将modal换成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,模态对话框会隐藏地址栏,而在其他浏览器则不一定
【注意】在谷歌浏览器中,这个模态的效果也会失效。
5. 一般在弹出对话框的时候,我们都希望整个父页面的背景变为一个半透明的颜色,让用户看到后面是不可以访问的
而关闭对话框之后又希望还原
这是怎么做到的呢?
复制代码 代码如下:
///显示某个订单的详细信息,通过一个模态对话框,而且屏幕会变颜色 
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,有一个样式表定义
复制代码 代码如下:
.body1 
{ 
background-color:#999999; 
filter:Alpha(Opacity=40); 
}  
6. 如何在页面之间传递数值 
showModalDialog 传值及刷新 
(一)showModalDialog使用例子,父窗口向子窗口传递值,子窗口设置父窗口的值,子窗口关闭的时候返回值到父窗口.
farther.html  
复制代码 代码如下:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> 
<HTML> 
<HEAD> 
<TITLE>New Document </TITLE> 
<META content="EditPlus" name="Generator"> 
<META content="" name="Author"> 
<META content="" name="Keywords"> 
<META content="" name="Description"> 
<script language="javascript"> 
<!-- 
function openChild(){ 
var k = window.showModalDialog("child.html",window,"dialogWidth:335px;status:no;dialogHeight:300px"); 
if(k != null) 
document.getElementById("txt11").value = k; 
} 
//--> 
</script> 
</HEAD> 
<BODY> 
<FONT face="宋体"></FONT> 
<br> 
传递到父窗口的值:<input id="txt9" type="text" value="3333333333333" name="txt9"><br> 
返回的值:<input id="txt11" type="text" name="txt11"><br> 
子窗口设置的值:<input id="txt10" type="text" name="txt10"><br> 
<input id="Button1" onclick="openChild()" type="button" value="openChild" name="Button1"> 
</BODY> 
</HTML>  
child.html
复制代码 代码如下:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> 
<HTML> 
<HEAD> 
<TITLE>New Document </TITLE> 
<META content="EditPlus" name="Generator"> 
<META content="" name="Author"> 
<META content="" name="Keywords">

<meta http-equiv="Pragma" content="no-cache"> 
</HEAD> 
<BODY> 
<FONT face="宋体"></FONT> 
<br> 
父窗口传递来的值:<input id="txt0" type="text" name="txt0"><br> 
输入要设置父窗口的值:<input id="txt1" type="text" name="txt1"><input id="Button1" onclick="setFather()" type="button" value="设置父窗口的值" name="Button1"><br> 
输入返回的值:<input id="txt2" type="text" name="txt2"><input id="Button2" onclick="retrunValue()" type="button" value="关闭切返回值" name="Button2"> 
<input id="Button3" onclick="" type="button" value="关闭刷新父窗口" name="Button3"> 
<script language="javascript"> 
<!-- 
var k=window.dialogArguments; 
//获得父窗口传递来的值 
if(k!=null) 
{ 
document.getElementById("txt0").value = k.document.getElementById("txt9").value; 
} 
//设置父窗口的值 
function setFather() 
{ 
k.document.getElementById("txt10").value = document.getElementById("txt1").value 
} 
//设置返回到父窗口的值 
function retrunValue() 
{ 
var s = document.getElementById("txt2").value; 
window.returnValue=s; 
window.close(); 
} 
//--> 
</script> 
</BODY> 
</HTML>  
说明: 
由于showModalDialog缓存严重,下面是在子窗口取消客户端缓存的设置.也可以在服务器端取消缓存,参考: 
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)下面是关闭刷新父窗口的例子
farther.html  
复制代码 代码如下:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> 
<HTML> 
<HEAD> 
<TITLE>New Document </TITLE> 
<META NAME="Generator" CONTENT="EditPlus"> 
<META NAME="Author" CONTENT=""> 
<META NAME="Keywords" CONTENT=""> 
<META NAME="Description" CONTENT=""> 
<script language="javascript"> 
<!-- 
function openChild() 
{ 
var k = window.showModalDialog("child.html",window,"dialogWidth:335px;status:no;dialogHeight:300px"); 
if(k == 1)//判断是否刷新 
{ 
alert('刷新'); 
window.location.reload(); 
} 
} 
//--> 
</script> 
</HEAD> 
<BODY> 
<br> 
传递到父窗口的值:<input id="txt9" type="text" value="3333333333333" NAME="txt9"><br> 
<input type="button" value="openChild" onclick="openChild()" ID="Button1" NAME="Button1"> 
</BODY> 
</HTML>  
child.html
复制代码 代码如下:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> 
<HTML> 
<HEAD> 
<TITLE>New Document </TITLE> 
<META content="EditPlus" name="Generator"> 
<META content="" name="Author"> 
<META content="" name="Keywords"> 
<META content="" name="Description"> 
<meta http-equiv="Expires" content="0"> 
<meta http-equiv="Cache-Control" content="no-cache"> 
<meta http-equiv="Pragma" content="no-cache"> 
</HEAD> 
<BODY> 
<FONT face="宋体"></FONT> 
<br> 
父窗口传递来的值:<input id="txt0" type="text" name="txt0"><br> 
<input id="Button1" onclick="winClose(1)" type="button" value="关闭刷新父窗口" name="Button1"> 
<input id="Button2" onclick="winClose(0)" type="button" value="关闭不刷新父窗口" name="Button2"> 
<script language="javascript"> 
<!-- 
var k=window.dialogArguments; 
//获得父窗口传递来的值 
if(k!=null) 
{ 
document.getElementById("txt0").value = k.document.getElementById("txt9").value; 
} 
//关闭窗口返回是否刷新的参数. 
function winClose(isRefrash) 
{ 
window.returnValue=isRefrash; 
window.close(); 
} 
//--> 
</script> 
</BODY> 
</HTML>  
说明 
1.下面是取消客户端缓存的: 
<meta http-equiv="Expires" CONTENT="0"> 
<meta http-equiv="Cache-Control" CONTENT="no-cache"> 
<meta http-equiv="Pragma" CONTENT="no-cache"> 
也可以在服务器端取消缓存,参考: 
http://adandelion.cnblogs.com/articles/252137.html 
2.向父窗口传递阐述在ASP.NET中也可以是用aaa.aspx?id=1的方式传递. 
3.不刷新父窗口的话在父窗口中直接这样一来设置可以. 
<script> 
window.showModalDialog("child.html",window,"dialogWidth:335px;status:no;dialogHeight:300px"); 
</script> 
4.在子窗口中若要提交页面的话要加入:,这样就不会打开新窗口了. 
<head> 
<base target="_self"> 
</HEAD>
