Ajax写成绩批量录入

1.jsp，ajax的循环调用，必须要递归，否则会出错。

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

　2.action，就是简单的一条数据一条数据的保存，一定有get和set，注意Spring注入不能写get，会报错。

public String BatchScoreSave() throws Exception{
		score = new Score();
		score.setId(new ScoreId());
		score.getId().setClasss(classs);
		score.getId().setCourse(course);
		score.getId().setNumber(number);
		score.getId().setName(name);
		score.getId().setScore(scores);
		mgr.Scoresave(score);
		
		return SUCCESS;
	}

　3.struts.xml

<package name="aaa" extends="json-default">

<action name="BatchScoreSave" class="ScoreAction" method="BatchScoreSave">
			<result name="success" type="json">
			<param name="root"></param>
			</result></action>

data:$('#form').serialize(),
