<swiper class="swiper" @change="swiperChange" next-margin="100rpx" :current='current' :autoplay="false" :circular="true">
<swiper-item v-for="item in sharePics" :key="item.id" >
<!-- <image :src="shareImage[item.id].img" class="swiper-item" mode=""></image> -->
<canvas class="canvas" :canvas-id="'Canvas'+item.id"></canvas>
</swiper-item>
</swiper>
就是放在swiper里就不行 放在外面就行
