ExtJS6官方文档推荐使用Ext.on。做一个小例子，创建一个Panel显示在页面上，使它的大小随浏览器变化，自适应浏览器窗口大小。
html：增加一个css样式给Panel加上红色border。
<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>ExtOnResize测试</title> <meta charset="utf-8" /> <link rel = "stylesheet" type = "text/css" href = "/ExtJS60/classic/theme-classic/resources/theme-classic-all.css" /> <style type="text/css"> .PanelCls { border: solid 1px red; padding: 8px; } </style> <script src="/ExtJS60/ext-all.js"></script> <script src="/ExtJS60/classic/locale/locale-zh_CN.js"></script> <script src="/Scripts/ExtOnResize_client.js"></script> </head> <body> </body> </html>
ExtOnResize_client.js
var mMainPanel; Ext.onReady(function () { //Ext.Msg.alert("Ready", "\ElectricStation\ExtJSMVC2016\Scripts\ExtOnResize_client.js<br/>ExtJS就绪"); mMainPanel = Ext.create('Ext.panel.Panel', { renderTo: Ext.getBody(), //bodyCls:'PanelCls', cls: 'PanelCls', height: window.innerHeight, window.innerWidth }); Ext.on('resize', function (width, height) { mMainPanel.setWidth(width); mMainPanel.setHeight(height); }); });
mMainPanel是全局变量。
