1. 标准的方法
<mce: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+";"); } // --></mce:script>
例：<span style="CURSOR: pointer" onclick="openWin
(’http://www.deepteach.com’, ’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
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
<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. 如何在页面之间传递数值
(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.

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:
