vue滑動(dòng)刪除的問題，滑動(dòng)刪除是整個(gè)元素列表，而不是選中的元素

應(yīng)該是向左滑動(dòng)某個(gè)元素出現(xiàn)刪除的div 現(xiàn)在是只要向左滑動(dòng) 整個(gè)列表都會(huì)出現(xiàn)

  <div class="order-list" :selectFoods="selectFoods">
        <ul>
          <transition-group name="slide-fade">       
            <li v-for = '(food,index) in selectFoods' class="cartList slide-warp" :key="food.name" ref="slideWarp">
              <div style="float: left;" class="slide-item" :data-index="index">{{food.name}}</div>
              <div class="cartControl">
                <span @click = "addFood(food)" class="addFood">+</span>
                <b>{{food.count}}</b>
                <span @click = 'decreaseFood(food)' class="decreaseFood">-</span>
                <span>價(jià)格：￥{{food.count * food.price}}</span>
              </div>
              <div class="slide-del">刪除</div>
            </li>

          </transition-group>
        </ul>
      </div>
