请求数据

  async getList() {
    let data = {
      "model": "1",
      "pageSize": this.data.pageSize,
      "pageNum": this.data.pageNum
    }
    let res = await subCertificate(data)
    if (res.resultStates !== 0) {
      return Dialog.alert({
        title: '提示',
        message: '暂无该车辆相关数据',
      }).then(() => {});
    }
    let list = res.content.taskVoList
    if (this.data.pageNum > 1) {
      list = this.data.list.concat(res.content.taskVoList)
    }
    this.setData({
      list: list,
      total: res.content.total,
      vin: res.content.vin
    })
  },

上拉加载数据

onReachBottom: function () {
    let num = Math.ceil(this.data.total / 5)//向上取整
    var self = this;
    if (this.data.pageNum >= num) {
      Dialog.alert({
        title: '提示',
        message: '没有更多数据了',
      }).then(() => {});
    } else {
      var pageNumber = self.data.pageNum + 1;
      self.setData({
        pageNum: pageNumber,
      })
      this.getList()
    }
  },
