PHP and jQuery realize the display effect of the three-level navigation bar drop-down menu
This article mainly introduces the display effect of the three-level navigation bar drop-down menu implemented by php+jQuery, involving php array traversal and jQuery event response operation page element transformation and other related operation skills. Friends in need can refer to it. I hope it can help everyone.
First look at the renderings:
1. Data configuration file db.php
<?php return array( array( 'one' => '关于我们', 'two' => array( array( 'three_tit' => '公司介绍', 'three_cont' => array( '企业概况', '组织架构', '发展历程', '企业文化', '服务理念' ) ), array( 'three_tit' => '企业荣誉', 'three_cont' => array( '获奖证书', '行业贡献', '资质认证', '协会活动', '公司的成就') ), array( 'three_tit' => '销售网络', 'three_cont' => array( '东北', '华北', '中东', '华南', '西南', '西北' ) ) ) ), array( 'one' => '产品展示', 'two' => array( array( 'three_tit' => '进出口贸易', 'three_cont' => array( '数码产品', '最新能源', '新鲜水果', '肉类食品', '衣服', '金银首饰' ) ), array( 'three_tit' => '商业服务', 'three_cont' => array( '资格认证', '人才培养', '热门商品推荐', '最新科技前沿' ) ) ) ), array( 'one' => '新闻中心', 'two' => array( array( 'three_tit' => '企业动态', 'three_cont' => array( '公司新闻', '新品上市', '企业动态' ) ), array( 'three_tit' => '行业动态', 'three_cont' => array( '媒体聚焦', '业内关注', '国内行情', '国际行情' ) ) ) ), array( 'one' => '联系我们', 'two' => array( array( 'three_tit' => '联系方式', 'three_cont' => array( '在线客服', '通信地址', '电话传真', '在线留言' ) ), array( 'three_tit' => '人才招聘', 'three_cont' => array( '项目经理', '助理秘书', '渠道代理', '网站工程师' ) ) ) ) ); ?>
2.index file
<?php header('Content-type:text/html;charset=utf-8'); // 载入数据 $data = include './db.php'; // 载入html文件 include './nav.html'; ?>
