<view class="con-part2-con">
    <swiper class="swiper-tall" :autoplay="true" :interval="3000" :duration="1000"
        circular='true' previous-margin='260rpx' current='0' @change="partSwiperChange">
        <swiper-item class="con-part2-con-container"
            v-for="(item,index) in partSwiperChangeList" :key="index">
            <view :class="['slide-image', partcurrentIndex === index?'active':'']"
                :style="{background:'url('+ item.pic +') center no-repeat',backgroundSize:'100%'}">
                <view class="part2-con-title">{{item.title}}</view>
                <view class="part2-con-img">
                    <image :src="item.img" class="img"></image>
