获取表单的值

1.document.byID

2.$.(id).val

3给表单起个名字

4 a标签中为了保险要写"javascript： ；

< a href=“javascript:toPage(${pageIndex-1 });”>上一页< /a>

function toPage(pageIndex){

frm.pageIndex.value= pageIndex;

}

< form name=“frm” action=“ToPageServlet” method=“post”>

< input type=“hidden” name=“pageIndex”>

分页将表单的值再点击每一页是都获取到，传入到servlet.

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

pageEncoding=“UTF-8”%>

<%@ taglib uri=“http://java.sun.com/jsp/jstl/core” prefix=“c”%>
