时间：2022-03-14 23:56:30

　  本章案例为通过js，动态操作table，实现在单页面进行增删改查的操作。

　　简要案例如下：

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

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

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>

<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>

<%@page import="java.util.Date"%>

<c:set var="ctx" value="${pageContext.request.contextPath}" />
