关于ExtJS 提交表单到StrutsAction的问题

micro_sun_ibm 2010-06-30 09:41:39

我现在用ExtJs写了文本框然后点发布将内容提交到 action页面然后存入DB
现在出现一个问题
我现在输入内容点提交后 action中是可以接收到值
但是状态栏报了个JS的错误
提示说是
n为空或不是对象
找了半天也没找到错误的地方大家帮我看下到底是哪引发的错误

贴代码：

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%@taglib uri="/struts-tags" prefix="s"%>

<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>

<link rel="stylesheet" type="text/css"

	href="../resources/css/ext-all.css" />

<script type="text/javascript" src="../adapter/ext/ext-base.js"></script>
