小程序 上下拉刷新

1. 上拉刷新
   pageView自带上拉刷新方法onReachBottom 实现方法并实现刷新事件

  onReachBottom() {
    if (!this.data.noMoreData) {
      this.loadData(true);
    }
  }

2.下拉刷新 需要在对应page页面的json文件中配置 然后在该页面的js文件中实现下拉刷新的方法即可

  "enablePullDownRefresh": true,
  "backgroundTextStyle": "dark"
   onPullDownRefresh(){
   this.loadData();
  }

  //结束上拉刷新loading关闭
  wx.stopPullDownRefresh();   

刷新数据

  //加载网络数据
  loadData: function (isMore = false) {
    var { page } = this.data;
    var { limit } = this.data;
    if (isMore) {
      page++;
    } else {
      page = 1;
    }
    this.setData({ page, limit });
    let activityRequest = require('../../utils/request');
    let urlConst = require('../../utils/api');
    activityRequest(urlConst.Action_Activity, {
      'page': page,
      'limit': limit
    }).then((res) => {
      if (res.code == 0) {
        var resData = res.data;
        //取出对应值
        var acts = resData.data || [];
        var adxs = resData.ads || [];
        // 处理tags
        acts.forEach((res, index) => {
          let list = res.tags.split(',');
          res['mytags'] = list;
        });
        //从data中取出activitys ads
        var { activitys } = this.data;
        var { ads } = this.data;
        if (!isMore) {
          //结束上拉刷新loading
          wx.stopPullDownRefresh();
          activitys = [];
        }
        var { noMoreData } = this.data;
        if (acts.length < this.data.limit) {
          console.log('暂无更多数据');
          noMoreData = true;
        }else{
          noMoreData = false;
        }
        ads = adxs;
        activitys = activitys.concat(acts);
        this.setData({
          ads,
          activitys,
          noMoreData
        });
      } else {
        if(!isMore){
          //结束上拉刷新loading
          wx.stopPullDownRefresh();
        }
        wx.showToast({
          title: res.message,
          icon: 'none'
        })
      }
    });
  },
