模态窗口和非模态窗口

对话框一般分为两种类型：模态类型（modal）与非模态类型（modeless）。所谓模态对话框，就是指除非采取有效的关闭手段，用户的鼠标焦点或者输入光标将一直停留在其上的对话框。非模态对话框则不会强制此种特性，用户可以在当前对话框以及其他窗口间进行切换。本文介绍如何使用JavaScript语言来创建这两种类型的对话框、控制其大小和位置、改变其外观以及在对话框间的数据传递。(引用)
一、创建模态和非模态对话框

创建模态对话框：（会缓存最近一次页面的值，通过一些设置可绕过系统的判断）
vReturnValue = window.showModalDialog(sURL [, vFreeArgument] [, sOrnaments]);
创建非模态对话框：（不会）
vReturnValue = window.showModelessDialog(sURL [, vFreeArgument] [, sOrnaments]);

· VReturnValue：对于showModalDialog()，它表示被打开的对话框窗口设置的returnValue属性值。对于showModelessDialog()，它表示新窗口对象。 
· VFreeArgument：这个参数可用于传递某种类型的数据到打开的对话框，数据可以是一个数值、字符串、数组或者一个对象类型。在新窗口中引用这个数值时，可通过新创建window对象的dialogArguments 属性。 
· SOrnaments：用这个参数指定新窗口的外观。可选择的窗口属性有很多种，当有多种控制需求时，将相关内容用一个字符串连接起来，其间用分号隔开。以下是可选择的属性种类： 
o dialogHeight: sHeight 
o dialogLeft: sXpos 
o dialogTop: sYpos 
o dialogWidth: sWidth 
o center: ( yes | no | 1 | 0 | on | off ) 
o dialogHide: ( yes | no | 1 | 0 | on | off ) 
o edge: ( sunken | raised ) 
o help: ( yes | no | 1 | 0 | on | off ) 
o resizable: ( yes | no | 1 | 0 | on | off ) 
o scroll: ( yes | no | 1 | 0 | on | off ) 
o status: ( yes | no | 1 | 0 | on | off ) 

二、控制对话框大小和位置

三、改变对话框外观
 
四、从Noname1.html页面传递数据到Noname2.html页面

//在Url的地方可以跟上一个.do的请求，基于struts架构时可以链接到某一个具体的页面，体现了窗口作为显示的作用
 
   //在模态窗口打开新窗口
在模态窗口的head部分添加如下代码
