Swiper实现导航栏滚动效果

<link rel="stylesheet" href="../css/swiper.css" >
<script src="/UploadFiles/2021-04-02/jquery-1.7.1.js">

2、编写view(界面)


<div class="box">
 <div class="swiper-container">
 <div class="swiper-wrapper">
 <div class="swiper-slide">综合</div>
 <div class="swiper-slide">单曲</div>
 <div class="swiper-slide">视频</div>
 <div class="swiper-slide">歌手</div>
 <div class="swiper-slide">专辑</div>
 <div class="swiper-slide">歌单</div>
 <div class="swiper-slide">主播电台</div>
 <span></span>
 </div>
 </div>
</div>


3、编写style


*{
 margin: 0;
 padding: 0;
 }
 .box{
 width: 500px;
 height: 50px;
 border: 1px solid #000;
 margin: 100px auto;
 }
 .swiper-container{
 width: auto!important;
 height: 100%;
 text-align: center;
 line-height: 50px;
 color: #000;
 font-size: 20px;
 }
 .swiper-wrapper{
 position: relative;
 width: auto!important;
 height: 100%;
 }
 .swiper-slide {
 list-style: none;
 display: flex;
 justify-content: flex-start;
 flex-wrap: nowrap;
 cursor: pointer;
 }
 .swiper-wrapper span{
 position: absolute;
 height: 3px;
 background: #000;
 left: 1%;
 top: 85%;
 }
 .swiper-slide{
 width: auto!important;
 margin-right: 15px!important;
 padding: 0 18px;
 }


为了让每个swiper-slide的宽度由内容撑起，右边显示一半是提示用户这个导航栏是可以滚动的，所以在初始化时要设置swiper的slidesPerView为auto，slidesPerView: “auto”, 同时要在css设置swiper-slide的样式为：


 .swiper-slide{
 width: auto!important;
 margin-right: 15px!important;
 padding: 0 18px;
 }



这样swiper-slide的宽度就是由内容撑起了，而且可以自由的进行滚动了

4、编写js


$(function () {
 $(".swiper-wrapper span").css({width: $(".swiper-slide")[0].offsetWidth});
 let navScroll = new Swiper('.box .swiper-container', {
 freeMode:true,
 slidesPerView: "auto",
 freeModeMomentumRatio: 0.5,
 on:{
 //当前swiper-slide点击时触发事件
 click:function (e) {
  let thisWidth = this.clickedSlide.offsetWidth;
  let thisLeft = this.clickedSlide.offsetLeft;
  let offsetX = this.width / 2 - thisLeft - thisWidth / 2;
  //偏移量在1/2视口内时，容器不发生偏移
  if (offsetX > 0){
  offsetX = 0;
  }
  //offsetX小于容器最大偏移时，让偏移量等于容器最大的偏移量
  else if (offsetX < this.maxTranslate()){
  offsetX = this.maxTranslate();
  }
  //设置容器的过渡动画
  this.setTransition(300);
  this.setTranslate(offsetX);
  //滚动条位置和长度执行动画
  $(".swiper-wrapper span").animate({left: thisLeft, width: thisWidth},400);
 }
 }
 });
 })
