Ext.container.Viewport代表浏览器窗口的整个区域,将document body作为渲染对象,它会根据浏览器窗口的大小自动调整自身的尺寸,在一个页面中只允许出现一个Viewport实例。此外它没有提供对滚动条的支持,如果需要使用滚动条需要在其子面板中进行设置。
1、简单示例
HTML代码:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Ext.container.Viewport</title> <link href="ext-4.0.7-gpl/resources/css/ext-all.css" rel="stylesheet" type="text/css" /> <script src="ext-4.0.7-gpl/bootstrap.js" type="text/javascript"></script> <script type="text/javascript"> Ext.onReady(function () { Ext.create("Ext.container.Viewport", { layout: "border", items: [{ title: "North Pannel", html: "上", region: "north", height: 100 }, { title: "West Pannel", html: "左", region: "west", 150 }, { title: "Main Pannel", html: "中", region: "center" }] }); }); </script> </head> <body> </body> </html>
