swiper实现竖直方向滚动字幕

垂直方向的滚动在开发过程中遇到的问题主要有2个，一个是移动端无法滚动，一个是每次数据循环完成之后sweiper都从第一条数据开始导致字幕快速滚动之后才正常滚动，原因是没有设置循环滚动

解决：移动端添加属性 observer: true,  observeParents: true, 对数据进行监听

添加 loop : true属性解决每次都从头开始滚动，之前添加过这个属性没好使后来又可以了

注意：swiper-wrapper不能添加overflow:scroll样式，不然会导致swiper-no-swiping无效

<template>

    <div class="live-lottery-notice" v-show="logList.length > 0">

        <div class="swiper-container swiper-no-swiping">

            <div class="swiper-wrapper">

                <div class="swiper-slide" v-for="(item, index) in logList" :key="index">XXX</div>

            </div>

        </div>

    </div>

        initSwiper() {

            this.$nextTick(()=> {

                setTimeout(()=>{
