<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
<link rel="stylesheet" href="ExtJS/resources/css/ext-all.css"
type="text/css">
<script src="ExtJS/ext-all.js"></script>
<script type="text/javascript">
Ext.onReady(function(){
Ext.Msg.alert("提示","到底我该怎么说");
});
</script>
</head>
<body>
</body>
</html>
结果：
Ext.onReady()用来注册在Ext框架及html代码加载完后所要执行的函数
