[移动开发]微信小程序 上拉加载与下拉分页

1.下拉刷新，需要在window开启全局配置

"enablePullDownRefresh": true

2.在data里设置当前页为1

data: {
        page: 1
    },

2页面刷新展示

onPullDownRefresh: function () {
        let that = this;
        let page = this.data.page; //获取当前的页数
        wx.request({
            url: 'http://www.day.com/index.php/admin/activity', //仅为示例，并非真实的接口地址
            header: {
                'content-type': 'application/json'
            },
            data: {
                page: page + 1
            },
            success(res) {
                let activityData = res.data.data.data;
                that.setData({
                    activity: activityData,
                    page: page,
                })
                if (activityData.length > 0) {
                    wx.showToast({
                        title: '刷新成功',
                        icon: 'success'
                    })
                }
            }
        })
    },

3.上拉展示

onReachBottom: function () {
        console.log("上拉了");
        let that = this;
        let page = this.data.page;
        wx.request({
            url: 'http://www.day.com/index.php/admin/activity', //仅为示例，并非真实的接口地址
            header: {
                'content-type': 'application/json' // 默认值
            },
            data: {
                page: page + 1,
            },
            success(res) {
                console.log(res.data.data);
                let value = res.data.data.data;
                that.setData({
                    activity: that.data.activity.concat(value),
                    page: page + 1,
                })

                if (value.length > 0) {
                    wx.showToast({
                        title: '正在加载数据中...',
                        icon: 'loading'
                    })
                } else {
                    wx.showToast({
                        title: '暂无最新的数据了...',
                        icon: 'none'
                    })
                }
            }
        })
    },
