我們在學校裡學習任何一門語言都是從"Hello World"開始，這裡我們也不例外。
那麼我們的教程就從 Hello World 講起。
helloWorld.js
Ext.onReady(function() {
Ext.MessageBox.alert('系統提示', 'Hello World!');
});helloWorld.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <title>hello Word</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- 引入ExtJs樣式 --> <link rel="stylesheet" type="text/css" href="<%=basePath %>static/ext-6.0.0.415/build/classic/theme-neptune/resources/theme-neptune-all.css"> <!-- 引入ExtJs核心Js --> <script type="text/javascript" src="<%=basePath %>static/ext-6.0.0.415/ext-bootstrap.js"></script> <script type="text/javascript" src="<%=basePath %>static/ext-6.0.0.415/build/ext-all.js"></script> <script type="text/javascript" src="<%=basePath %>static/ext-6.0.0.415/build/classic/locale/locale-zh_CN.js"></script> <!-- 頁面Js --> <script type="text/javascript" src="<%=basePath %>static/js/helloWord.js"></script> </head> <body> </body> </html>
說明：
(1)Ext.onReady():ExtJS Application的入口...就相當於Java或C#的main函式.
(2)Ext.MessageBox.alert()：彈出對話方塊。
