struts1.X关于表单提交时action执行两次的问题
今天写一个简单的登录功能，代码如下：
//=================================================================================
//============================ index.jsp =========================================
//=================================================================================
<%@ page language="java" contentType="text/html;charset=GBK"%>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html"%>
<%
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>Welcome to myweb</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="styles.css">
-->
<script type="text/javascript">
function login()
{
loginForm.submit();
}
</script>
</head>
<body>
This is my JSP page. <br>
<html:form action="login?methods=login" method="POST">
u:<html:text property="userName"></html:text><br/>
p:<html:password property="passWord"></html:password>
</html:form>
<html:button property="s" value="submitform" onclick="login()"/>
</body>
</html>

import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.actions.DispatchAction;
import com.myweb.bean.LoginForm;
public class LoginAction extends DispatchAction {
private final Logger logger = Logger.getLogger(LoginAction.class);
public ActionForward login(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {
LoginForm loginForm = (LoginForm)form;
logger.info(loginForm.getUserName() + ":" + loginForm.getPassWord());
return mapping.findForward("login");
}
}
===========================================================================================
每当点击按钮进行登录时，action总是被执行两遍，就是说log文件中存在两条logger.info（）所打印出来的信息
大家帮忙解决一下，这是为什么？
[解决办法]
submit行为就提交了，然后再调用javascript的提交就2次了呗。
楼主换普通button调用javascript试试看呢？
good luck

4楼是对的
