当然,这里是一个基本的 HTML 导航栏源码示例:,,“`html,,,,,导航栏示例,,,,,首页,
导航栏源码通常包含HTML、CSS和JavaScript三个部分,用于构建网页顶部或底部的导航菜单,以下是一些详细的导航栏源码示例:
1. HBuilderX MUI模板底部导航栏实例(附源码)
HTML部分:
<!DOCTYPE html> <html lang="zh"> <head> <meta charset="UTF8"> <title>底部导航栏实例</title> <script src="js/mui.min.js"></script> <link href="css/mui.min.css" rel="stylesheet"/> <link href="font_ico/iconfont.css" rel="stylesheet"/> <link href="css/header.css" rel="stylesheet"/> <style type="text/css"> * { touchaction: none; } </style> </head> <body> <nav class="muibar muibartab"> <a class="muitabitem muiactive" id="home.html" href="home.html"> <span class="muiicon muiiconhome"></span> <span class="muitablabel">首页</span> </a> <a class="muitabitem" id="yemianyi.html" href="yemianyi.html"> <span class="muiicon muiiconphone"></span> <span class="muitablabel">页面一</span> </a> <a class="muitabitem" id="yemianer.html" href="yemianer.html"> <span class="muiicon muiiconemail"></span> <span class="muitablabel">页面二</span> </a> <a class="muitabitem" id="yemiansan.html" href="yemiansan.html"> <span class="muiicon muiicongear"></span> <span class="muitablabel">页面三</span> </a> </nav> </body> </html>
JavaScript部分:
<script type="text/javascript"> mui.init(); // 移动设备就绪完成后 mui.plusReady(function() { plus.navigator.setStatusBarStyle("dark");//需要修改manifest中的plus:statusbar:immersed为true才能生效,参数为light(白),dark(黑) // 创建子页面数组 var subpages = ['home.html','yemianyi.html','yemianer.html','yemiansan.html']; var subpage_style = { top: '20px',//需要修改manifest中的plus:statusbar:immersed为true才能生效 bottom: '50px' }; //获取当前窗体 var self = plus.webview.currentWebview(); for (var i = 0; i < subpages.length; i++) { //创建子窗体 //参数顺序: 窗体内容对应html路径,窗体唯一名字id, 窗体样式, 给窗体传参 var subview = plus.webview.create(subpages[i], subpages[i], subpage_style, null); //子窗台隐藏 subview.hide(); //添加子窗体到当前窗体 self.append(subview); } //设置默认显示的子窗体 plus.webview.show('home.html'); //切换子窗体 mui(".muibartab").on("tap", "a", function(e) { //获取被点击的a标签的href属性值 var subid = this.getAttribute("href"); //参数: 窗体id,切换效果,切换时间,展示对应的页面 plus.webview.show(subid) }) }); </script>
2. 响应式导航栏(使用HTML、CSS和JavaScript)
HTML部分:
<!DOCTYPE html> <html lang="zhCN"> <head> <meta charset="UTF8"> <title>响应式导航栏示例</title> <link rel="stylesheet" href="path/to/your/stylesheet.css"> </head> <body> <nav class="navbar"> <div class="logo">My Website</div> <ul class="navlinks"> <li><a href="#">首页</a></li> <li><a href="#">关于我们</a></li> <li><a href="#">服务</a></li> <li><a href="#">联系</a></li> </ul> <div class="menuicon" id="menuicon"> <span></span> <span></span> <span></span> </div> </nav> </body> </html>
CSS部分:
{ margin: 0; padding: 0; boxsizing: borderbox; } .navbar { display: flex; justifycontent: spacebetween; alignitems: center; backgroundcolor: #34495e; padding: 10px 20px; color: #ecf0f1; } .logo { fontsize: 24px; fontweight: bold; } .navlinks { liststyle: none; display: flex; } .navlinks li { marginleft: 20px; } .navlinks a { textdecoration: none; color: #ecf0f1; fontsize: 18px; } .navlinks a:hover { color: #bdc3c7; } .menuicon { display: none; flexdirection: column; cursor: pointer; } .menuicon span { width: 25px; height: 3px; backgroundcolor: #ecf0f1; margin: 4px; transition: 0.3s; } @media screen and (maxwidth: 768px) { .navlinks { position: fixed; right: 100%; top: 60px; flexdirection: column; backgroundcolor: #34495e; width: 100%; height: calc(100vh 60px); transition: 0.3s; } .navlinks li { margin: 20px 0; } .menuicon { display: flex; } }
JavaScript部分:
document.getElementById('menuicon').addEventListener('click', () => { const navLinks = document.querySelector('.navlinks'); navLinks.classList.toggle('open'); // 假设有一个名为'open'的类来控制导航链接的显示和隐藏 });
3. Bootstrap导航栏示例(使用HTML和CSS)
HTML部分:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF8"> <meta name="viewport" content="width=devicewidth, initialscale=1.0"> <title>Bootstrap Navbar Example</title> <! Add Bootstrap CSS > <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css"> </head> <body> <nav class="navbar navbarexpandlg navbarlight bglight"> <a class="navbarbrand" href="#">Logo</a> <button class="navbartoggler" type="button" datatoggle="collapse" datatarget="#navbarNav" ariacontrols="navbarNav" ariaexpanded="false" arialabel="Toggle navigation"> <span class="navbartogglericon"></span> </button> <div class="collapse navbarcollapse" id="navbarNav"> <ul class="navbarnav"> <li class="navitem active"> <a class="navlink" href="#">Home <span class="sronly">(current)</span></a> </li> <li class="navitem"> <a class="navlink" href="#">Features</a> </li> <li class="navitem"> <a class="navlink" href="#">Pricing</a> </li> <li class="navitem"> <a class="navlink disabled" href="#" tabindex="1" ariadisabled="true">Disabled</a> </li> </ul> </div> </nav> <! Add Bootstrap JS and Popper.js for dropdown functionality > <script src="https://code.jquery.com/jquery3.5.1.slim.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.9.3/dist/umd/popper.min.js"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script> </body> </html>
这些示例展示了如何使用不同的技术和框架(如MUI、原生HTML/CSS/JavaScript和Bootstrap)来创建导航栏,根据具体需求和项目背景,可以选择适合的实现方式。
