        <!-- data-type=0 隐藏删除按钮 data-type=1 显示删除按钮 -->
        <li class="li_vessel" v-for="(item,index) in lists " data-type="0" :key="index">
          <!-- "touchstart" 当手指触摸屏幕时候触发  "touchend"  当手指从屏幕上离开的时候触发  "capture" 用于事件捕获-->
          <div @touchstart.capture="touchStart" @touchend.capture="touchEnd" @click="oneself">
            <div class="contant">
              <img class="image" :src="item.imgUrl" alt />
