首先导入
<link href="https://www.jb51.net/css/swiper.min.css" > <script src="https://www.jb51.net/js/jquery-1.10.1.min.js"></script> <script src="https://www.jb51.net/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> <h3>商品分类</h3> </div> <div> <ul> <li><a href="javascript:;" >手机</a></li> <li><a href="javascript:;">厨具</a></li> <li><a href="javascript:;">数码</a></li> <li><a href="javascript:;">家纺</a></li> <li><a href="javascript:;">生鲜</a></li> <li><a href="javascript:;">家用电器</a></li> <li><a href="javascript:;">食品饮料</a></li> <li><a href="javascript:;">电脑/办公</a></li> <li><a href="javascript:;">家用日用</a></li> </ul> </div> </div> <div> <div> <div>手机</div> <div>厨具</div> <div>数码</div> <div>家纺</div> <div>生鲜</div> <div>家用电器</div> <div>食品饮料</div> <div>电脑/办公</div> <div>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：
