如何使用vue实现轮播图片

<template>
       <section class="body">
           <section class="wrap">
               <swiper :options="swiperOption" class="swiper-wrap"  ref="mySwiper" v-if="banner.length!=0">
                   <swiper-slide v-for="(item,index) in banner" :key="index" >
                       //点击图片跳到哪里,这里跳到home页面 item举例：{img:http://www.***.com/home/images/index_img02.png,url:/home}
                       <img :src="item.img" alt="" @click="skip_out_page(item.url)" />
                   </swiper-slide>
                   <!-- 常见的小圆点 -->
                   <div class="swiper-pagination"  v-for="(item,index) in banner" :key="index" slot="pagination" ></div>
               </swiper>
           </section>
       </section>
</template>

<script>
    export default {
        data() {
            const that = this;
            return {
                imgIndex: 1,
                swiperOption: {
                    //是一个组件自有属性，如果notNextTick设置为true，组件则不会通过NextTick来实例化swiper，也就意味着你可以在第一时间获取到swiper对象，假如你需要刚加载遍使用获取swiper对象来做什么事，那么这个属性一定要是true
                    notNextTick: true,
                    //循环,而不是每次都突然回到第一个
                    loop: true,
                    //设定初始化时slide的索引，加载页面时显示的第几个，从0开始
                    initialSlide: 0,
                    //自动播放
                    autoplay: {
                        /*切换轮播图片的时间，即上次切换成功后到再次需要切换的时间*/
                        delay: 1500,
                        stopOnLastSlide: false,
                        /* 触摸滑动后是否继续轮播 false触摸后不再点击继续轮播，true触摸后不再点击不轮播，停在最后一次页面*/
                        disableOnInteraction: false
                    },
                    //滑动速度，时间单位，越小越快，与上面 delay 区别，speed是完成切换所需时间，delay是切换成功后停留多长时间再切换

                    direction: "horizontal",
                    //小手掌抓取滑动

                    on: {
                        //滑动之后回调函数
                        slideChangeTransitionStart: function() {
                            /* realIndex为滚动到当前的slide索引值 */
                            that.imgIndex= this.realIndex - 1;
