轮播图的导航，点点点变成文字

使用swiper插件2.7版本

前端页面部分，使用循环

<div class="swiper-container-top banner">
            <a class="arrow-left" href="#"></a>
            <a class="arrow-right" href="#" ></a>
            <div class="swiper-container">
                <div class="swiper-wrapper">
    <#list list_images?chunk(colSize) as list_chunk>
            <#list list_chunk as image>
 <div class="swiper-slide"><img alt="" src="${image.picUrl}" onclick="${image.addClicksFun}"></div>
            </#list>
    </#list>
                </div>
            </div>
            <div class="pagination"></div>
        </div>
        <div class="pagination1">
<#list list_images?chunk(colSize) as list_chunk>
            <#list list_chunk as image>
         <#if (image.pos == 1)>
        <span class="swiper-pagination-bullet swiper-pagination-bullet-active">平安吉祥</span>
        </#if>
        <#if (image.pos == 2)>
        <span class="swiper-pagination-bullet">万事如意</span>
        </#if>
        <#if (image.pos == 3)>
        <span class="swiper-pagination-bullet">心想事成</span>
        </#if>
        <#if (image.pos == 4)>
        <span class="swiper-pagination-bullet">马到成功</span>
        </#if>
        <#if (image.pos == 5)>
        <span class="swiper-pagination-bullet">龙年大吉</span>
        </#if>
            </#list>
    </#list>            
</div>

js部分

var mySwiper = new Swiper('.swiper-container', {
            loop: true,
            grabCursor: true,
            paginationClickable: true,
            autoplay: 3000,
            onSlideChangeEnd: function (swiper) {
                let index = $('.swiper-slide-active').index()
                // console.log(index)

                if (index == 6) {
                    index = 1
                }
                $('.pagination1 .swiper-pagination-bullet').eq(index - 1).addClass('swiper-pagination-bullet-active').siblings().removeClass('swiper-pagination-bullet-active')
            }
        })
