欢迎页面hello.jsp已经出来了，但是跳转到其他页面的时候，通过Struts标签可以跳转，通过javascript脚本就不能跳，请大家指点我一下，代码如下：

hello.jsp



<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean"%>

<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html"%>

<%@ taglib uri="http://jakarta.apache.org/struts/tags-logic" prefix="logic"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">



<html>

<head>

<title>STRUTS3</title>



<script type="text/javascript">

function jump(){

	document.forms[0].action = "/HelloWorld.do?verb=3";

	alert(document.forms[0].action);

	document.forms[0].submit();

}

</script>



</head>

	<body>

	<form>

		<html:link page="/HelloWorld.do?verb=1">HelloWorld_1</html:link>

		<html:link page="/HelloWorld.do?verb=2">HelloWorld_2</html:link>

		<input type=button value="3333" onclick="jump();"/>

	</form>

	</body>



</html>



struts-config文件：



<?xml version="1.0"?>

<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

      <forward name="Hello_2" path="/HelloWorld_2.jsp"/>

      <forward name="Hello_3" path="/HelloWorld_3.jsp"/>

    </action>

  </action-mappings>

  <controller/>

</struts-config>

action类：



package hello;



import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;



import org.apache.struts.action.Action;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionForward;

import org.apache.struts.action.ActionMapping;





public class HelloAction extends Action {





	public ActionForward execute(ActionMapping map, ActionForm form,

			HttpServletRequest request, HttpServletResponse response) throws Exception {

		

		String para = (String)request.getParameter("verb");

		

		if(para.equals("1")){

			return (map.findForward("Hello_1"));

		}

		if(para.equals("2")){ 

			return (map.findForward("Hello_2"));

		}

		if(para.equals("3")){

			return (map.findForward("Hello_3"));

		}

		else{

			return null;

			

		}

	}

}
