小程序下拉刷新上拉加载加搜索功能

上拉加载

小程序有内置函数可以实现上拉加载

data:{
 hasMoreData: true,
    page: 1,
    size: 10
},
  /**
   * 点击搜索 
   */
  getRecordSearch: function () {

    this.setData({
      ['form.startDate']: this.data.startTime,
      ['form.endDate']: this.data.endTime,
    })

    this.data.page = 1
    this.setData({
      getData: [],
      hasMoreData: true
    })

    this.getData('加载中')

  },
getData: function (message) {
    wx.showNavigationBarLoading()              //在当前页面显示导航条加载动画
    wx.showLoading({                        //显示 loading 提示框
      title: message,
    })
    let communityId = wx.getStorageSync('project').id
    wx.request({
      url: app.baseData.URL + '/patrol/appInterface/myPatrolTask?communityId=' + communityId + '&curPage=' + this.data.page + '&pageSize=' + this.data.size + '&status=' + this.data.status + '&Access-Token=' + wx.getStorageSync("token"),
      method: "post",
      complete() {
        wx.hideLoading();
        wx.hideNavigationBarLoading()
      },
      success: res => {
        if (res.data.error.err_code == 0 && res.data.list && res.data.list.length > 0) {


          let sendList = res.data.list, before = this.data.sendList;
          this.setData({
            sendList: [].concat(before, sendList)
          })
          if (sendList.length < this.data.size) {
            this.setData({
              hasMoreData: false
            })
          }
          console.log(this.data.hasMoreData)

        } else {
          wx.showToast({
            title: "暂无数据",
            icon: "none"
          })
        }

      },
      fail: err => {
        wx.showToast({
          title: '网络错误，请稍后重试',
          icon: "none"
        })
      }
    })
  },
 /**

  onPullDownRefresh: function () {
    console.log(33333)
    this.data.page = 1
    this.getData('正在刷新数据')
  },
