每日记录

对基础的框架进行了搭建：

导航栏：

<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%><!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Layui</title> <meta name="renderer" content="webkit"> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1"> <link rel="stylesheet" href="layui/css/layui.css" media="all"> <!-- 注意：如果你直接复制所有代码到本地，上述css路径需要改成你本地的 --> </head> <body> <ul class="layui-nav layui-bg-cyan"> <li class="layui-nav-item"><a href="数据下钻.jsp">科技成果</a></li> <li class="layui-nav-item"> <a href="javascript:;">分类</a> <dl class="layui-nav-child"> <dd><a href="资源与环境.jsp">资源与环境</a></dd> <dd><a href="现代农业.jsp">现代农业</a></dd> <dd><a href="材料与化工.jsp">材料与化工</a></dd> <dd><a href="电子信息.jsp">电子信息</a></dd> <dd><a href="生物与医药.jsp">生物与医药</a></dd> <dd><a href="先进制造与自动化.jsp">先进制造与自动化</a></dd> <dd><a href="社会公益.jsp">社会公益</a></dd> <dd><a href="行业.jsp">汇总</a></dd> </dl> </li> <li class="layui-nav-item"><a href="优缺点.jsp">优缺点</a></li> </ul> <script src="layui/layui.js" charset="utf-8"></script> <!-- 注意：如果你直接复制所有代码到本地，上述js路径需要改成你本地的 --> <script> layui.use('element', function(){ var element = layui.element; //导航的hover效果、二级菜单等功能，需要依赖element模块 //监听导航点击 element.on('nav(demo)', function(elem){ //console.log(elem)  layer.msg(elem.text()); }); }); </script> </body> </html>

还进行了省市县区的三级数据下钻;
