<script>  
    export default {  
        name: 'swiper-bar',  
        props: {   
          /**

             jumpPge(item){  
                 this.$emit('clickSwiper',item)  
             }  
        }  
    }     
</script>  

引入  
mport swiperBar from "@/components/jing-swiper/jing-swiper.vue"  
components:{swiperBar},  

使用  
<view class="contetn" >  
            <view class="yellow_local">  
                <view class="swiper">  
                    <swiper-bar :imgList="swiperList" @clickSwiper="goTetial"  :isPoint="true"></swiper-bar>  
                </view>  
            </view>  
        </view>
