      startX: 0, //滑动开始
      endX: 0, //滑动结束
    };
  },
  methods: {
    // 向左滑动出现删除按钮时，点击商品信息区域取消删除
    oneself() {
      if (this.checkSlide()) {
        this.restSlide();
      } else {
        // 点击商品信息弹出弹框
        alert("hello Word!");
      }
    },
    //滑动开始
    touchStart(e) {
      // 记录初始位置
      this.startX = e.touches[0].clientX;
    },
    //滑动结束

      let parentElement = e.currentTarget.parentElement;

      this.endX = e.changedTouches[0].clientX;
      // 左滑大于30距离删除出现
      if (parentElement.dataset.type == 0 && this.startX - this.endX > 30) {
        this.restSlide();
        parentElement.dataset.type = 1;
      }
      // 右滑
      if (parentElement.dataset.type == 1 && this.startX - this.endX < -30) {

      }
      this.startX = 0;
      this.endX = 0;
    },
    //判断当前是否有滑块处于滑动状态
    checkSlide() {
      let listItems = document.querySelectorAll(".li_vessel");
      for (let i = 0; i < listItems.length; i++) {
        if (listItems[i].dataset.type == 1) {
          return true;
        }
      }
      return false;
    },
    //复位滑动状态
    restSlide() {
      let listItems = document.querySelectorAll(".li_vessel");
      // 复位

    remove(e) {
      // 当前索引值
