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

传递对象类型数据
