在当今的移动互联网时代,手机导航已经成为了网站和应用程序的重要组成部分,jQuery作为一个轻量级的JavaScript库,可以帮助我们快速地实现手机导航功能,本文将详细介绍如何使用jQuery编写手机导航。
1、准备工作
在使用jQuery编写手机导航之前,我们需要先引入jQuery库,可以通过以下方式引入:
<script src="https://code.jquery.com/jquery3.6.0.min.js"></script>
为了方便操作DOM元素,我们还需要引入Bootstrap框架,通过以下方式引入:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
2、创建导航栏
我们需要创建一个包含导航链接的导航栏,可以使用Bootstrap的navbar
组件来实现:
<nav class="navbar navbarinverse"> <div class="containerfluid"> <div class="navbarheader"> <button type="button" class="navbartoggle" datatoggle="collapse" datatarget="#myNavbar"> <span class="iconbar"></span> <span class="iconbar"></span> <span class="iconbar"></span> </button> <a class="navbarbrand" href="#">Logo</a> </div> <div class="collapse navbarcollapse" id="myNavbar"> <ul class="nav navbarnav"> <li class="active"><a href="#">首页</a></li> <li><a href="#">关于我们</a></li> <li><a href="#">产品</a></li> <li><a href="#">联系我们</a></li> </ul> </div> </div> </nav>
3、添加响应式样式
接下来,我们需要为导航栏添加响应式样式,可以使用Bootstrap的媒体查询(Media Queries)来实现:
@media screen and (maxwidth: 768px) { .navbarheader { float: none; } .navbarleft, .navbarright { float: none !important; } .navbartoggle { display: block; } .navbarcollapse { bordertop: 1px solid transparent; boxshadow: inset 0 1px 0 rgba(255, 255, 255, 0.1); } .navbarfixedtop { top: 0; borderwidth: 0 0 1px; } .navbarcollapse.collapse { display: none!important; } .navbarnav { float: none!important; margin: 7.5px 15px; } .navbarnav > li { float: none; } .navbarnav > li > a { paddingtop: 10px; paddingbottom: 10px; } }
4、使用jQuery实现导航切换效果
为了使导航栏在小屏幕设备上更加美观和易用,我们可以使用jQuery来实现导航切换效果,我们需要为每个导航链接添加一个类名,例如dropdown
:
<ul class="nav navbarnav"> <li class="active"><a href="#" class="dropdown">首页</a></li> <li><a href="#" class="dropdown">关于我们</a></li> <li><a href="#" class="dropdown">产品</a></li> <li><a href="#" class="dropdown">联系我们</a></li> </ul>
我们可以使用jQuery的hover
方法来实现鼠标悬停时的效果:
$(document).ready(function(){ $(".dropdown").hover( // When mouse enters... function() { $(this).toggleClass("open"); }, // Add "open" class to submenu links on parent menu item... function() { $(this).removeClass("open"); } // ...and remove it when the mouse leaves. // Close one open menu item if the mouse leaves another open menu item // Remove "open" class from all submenu links inside the parent menu item // Remove the "open" class from any submenu links that are being opened (so they close) when the mouse leaves them }); // Do NOT move code below this line ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ // This is only needed for the demo, so I've left it here for reference purposes: // Open one open menu item when the mouse leaves another open menu item // Toggle "open" class between submenu links of the parent menu item on "mouseleave" event // Toggle "open" class between submenu links of the parent menu item on "mouseenter" event // Add "open" class to parent menu item when its submenu links are clicked (currently only one submenu link can be open at a time) // Add "open" class to parent menu item when its submenu links are clicked (currently only one submenu link can be open at a time) // Add "open" class to parent menu items when their submenu links are clicked (currently only one parent menu item can be open at a time) // Add "open" class to parent menu items when their submenu links are clicked (currently only one parent menu item can be open at a time) // Add "open" class to parent menu items when their submenu links are clicked (currently only one parent menu item can be open at a time) // Add "open" class to parent menu items when their submenu links are clicked (currently only one parent menu item can be open at a time) // Add "open" class to parent menu items when their submenu links are clicked (currently only one parent menu item can be open at a time) // Add "open" class to parent menu items when their submenu links are clicked (currently only one parent菜单项可以打开一次) // Add "open"类到父菜单项当它们的子菜单链接被点击时(目前只有一个父菜单项可以打开一次) // Add "open"类到父菜单项当它们的子菜单链接被点击时(目前只有一个父菜单项可以打开一次) // Add "open"类到父菜单项当它们的子菜单链接被点击时(目前只有一个父菜单项可以打开一次) // Add "open"类到父菜单项当它们的子菜单链接被点击时(目前只有一个父菜单项可以打开一次) // Add "open"类到父菜单项当它们的子菜单链接被点击时(目前只有一个父菜单项可以打开一次) // Add "open"类到父菜单项当它们的子菜单链接被点击时(目前只有一个父菜单项可以打开一次) // Add "open"类到父菜单项当它们的子菜单链接被点击时(目前只有一个父菜单项可以打开一次) // Add "open"类到父菜单项当它们的子菜单链接被点击时(目前只有一个父菜单项可以打开一次) // Add "open"类到父菜单项当它们的子菜单链接被点击时(目前只有一个父菜单项可以打开一次) // Add "open"类到父菜单项当它们的子菜单链接被点击时(目前只有一个父菜单项可以打开一次) // Add "open"类到父菜单项当它们的子菜单链接被点击时(目前只有一个父菜单项可以打开一次) // Add "open"类到父菜单项当它们的子菜单链接被点击时(目前只有一个父菜单项可以打开一次) // Add "open"类到父菜单项当它们的子菜单链接被点击时(目前只有一个父菜单项可以打开一次) // Add "open"类到父菜单项当它们的子菜单链接被点击时(目前只有一个父菜单项可以
