纯js写的分页表格数据为json串_javascript技巧



什么也不说了，直接上代码：
代码如下:
<%@ 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+"/";
%>

/**
page:页码
pageSize:每页的记录条数
此方法除了传入page和pageSize之外，还应知道的有三个参数：
一、表的全部数据，json串格式，可通过action查询数据库得到。
二、表头所对应的列的key及名称，也是json串格式
三、表所对应的id
注：此处只是适合表头只有一行，且事先写好的情况。您可以根据需要改一下，逻辑思路就是这样，欢迎批评指正。
