<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html> <head> <base href="<%=basePath%>"> <title>My JSP 'MyGrid.jsp' starting page</title> <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"><link rel="stylesheet" type="text/css" href="/extjs/resources/css/ext-all.css" /> <script type="text/javascript" src="/extjs/adapter/ext/ext-base.js"></script>  <script type="text/javascript" src="/extjs/ext-all.js"></script><script type="text/javascript" src="/extjs/ext-all-debug.js"></script> </head> <body><script type="text/javascript">var store = new Ext.data.Store();var cm = new Ext.grid.ColumnModel([{header : 'username',dataIndex : 'USERNAME',width : 200},{header : 'password',dataIndex : 'PASSWORD'}]);var myGridPanel = new Ext.grid.GridPanel({store : store,cm : cm});myGridPanel.render('mygrid');</script><div id="mygrid"></div></body></html>

以上代码会报ct is null的错误，但是，如果把<div id="mygrid"></div>代码放到body中<script>的前面，就正常显示，难道加载的时候，extjs只会找之前的，之后的不会找？,确实属于加载顺序的问题
