这篇文章主要为大家详细介绍了swiper4实现移动端导航切换,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

本文实例为大家分享了swiper4实现移动端导航切换的具体代码,供大家参考,具体内容如下

首先导入

<link rel="stylesheet" href="css/swiper.min.css" >
<script src="js/jquery-1.10.1.min.js"></script>
<script src="js/swiper.min.js"></script>(这里用的是Swiper 4.0.7版本)

在写入html内容

<div id=header>
 <div class="head-top">
 <h3>商品分类</h3>
 </div>
 <div id="nav" class="swiper-container">
 <ul class="swiper-wrapper">
  <li class="swiper-slide active-nav"><a href="javascript:;" >手机</a></li>
  <li class="swiper-slide"><a href="javascript:;">厨具</a></li>
  <li class="swiper-slide"><a href="javascript:;">数码</a></li>
  <li class="swiper-slide"><a href="javascript:;">家纺</a></li>
  <li class="swiper-slide"><a href="javascript:;">生鲜</a></li>
  <li class="swiper-slide"><a href="javascript:;">家用电器</a></li>
  <li class="swiper-slide"><a href="javascript:;">食品饮料</a></li>
  <li class="swiper-slide"><a href="javascript:;">电脑/办公</a></li>
  <li class="swiper-slide"><a href="javascript:;">家用日用</a></li>
 </ul>
 </div>
 </div>
 <div id="page" class="swiper-container" id="page">
 <div class="swiper-wrapper">
 <div class="swiper-slide slidepage">手机</div>
 <div class="swiper-slide slidepage">厨具</div>
 <div class="swiper-slide slidepage">数码</div>
 <div class="swiper-slide slidepage">家纺</div>
 <div class="swiper-slide slidepage">生鲜</div>
 <div class="swiper-slide slidepage">家用电器</div>
 <div class="swiper-slide slidepage">食品饮料</div>
 <div class="swiper-slide slidepage">电脑/办公</div>
 <div class="swiper-slide slidepage">家用日用</div>
 </div>
</div>

最后调用swiper

<script>
 var myNav = new Swiper('#nav', {
  spaceBetween: 10,
  slidesPerView : 3,
  watchSlidesProgress : true,
  watchSlidesVisibility : true,
  on:{
  tap: function(){
   myPage.slideTo( myNav.clickedIndex)
  }
  }
 })
 var myPage = new Swiper('#page',{
  on:{
  slideChangeTransitionStart: function(){
  updateNavPosition()
  }}
 })
 function updateNavPosition(){
  $('#nav .active-nav').removeClass('active-nav');
  var activeNav = $('#nav .swiper-slide').eq(myPage.activeIndex).addClass('active-nav');
  if (!activeNav.hasClass('swiper-slide-visible')) {
  console.log(1);
  if (activeNav.index()>myNav.activeIndex) {
   console.log(2);
   var thumbsPerNav = Math.floor(myNav.width/activeNav.width())-1
   myNav.slideTo(activeNav.index()-thumbsPerNav)
  }
  else {
   console.log(3);
   myNav.slideTo(activeNav.index())
  } 
  }
 }
</script>

全部代码如下:

<!DOCTYPE html>
<html lang="en">

 </div>
 <script>

  }
  }
 })
 var myPage = new Swiper('#page',{
  on:{

  }}
 })
 function updateNavPosition(){
  $('#nav .active-nav').removeClass('active-nav');
  var activeNav = $('#nav .swiper-slide').eq(myPage.activeIndex).addClass('active-nav');
  if (!activeNav.hasClass('swiper-slide-visible')) {
  console.log(1);
  if (activeNav.index()>myNav.activeIndex) {
   console.log(2);
   var thumbsPerNav = Math.floor(myNav.width/activeNav.width())-1
   myNav.slideTo(activeNav.index()-thumbsPerNav)
  }
  else {
   console.log(3);
   myNav.slideTo(activeNav.index())
  } 
  }
 }
 </script>
