使用 swiper 制作 导航，点击项居中

<div class="swiper-container">
    <div class="swiper-wrapper">
        <div class="swiper-slide">slider1</div>
        <div class="swiper-slide">slider2</div>
        <div class="swiper-slide">slider3</div>
        <div class="swiper-slide">slider4</div>
        <div class="swiper-slide">slider5</div>
        <div class="swiper-slide">slider6</div>
        <div class="swiper-slide">slider7</div>
        <div class="swiper-slide">slider8</div>
        <div class="swiper-slide">slider9</div>
    </div>
</div>

var mySwiper = new Swiper(‘.swiper-container‘, {
    //autoplay: true, //可选选项，自动滑动
    loop:true,//设置 active slide 居中后，会有左右留白现象，添加此会让未尾的导航补齐前后空白
    slideToClickedSlide: true,//设置为true则点击slide会过渡到这个slide。
    slidesPerView: 5,
    centeredSlides: true,//设定为true时，active slide会居中，而不是默认状态下的居左。
    spaceBetween: 10,
    slidesOffsetBefore: 0,
    slidesOffsetAfter: 0,
})

$(‘.swiper-container .swiper-slide‘).on("click",function(){
    //mySwiper.activeIndex   过渡到的 slide 位置 
    mySwiper.slideTo(mySwiper.activeIndex, 1000, false);//切换到指定slide，速度为1秒
    
})
