微信小程序 scroll-view实现上拉加载与下拉刷新的实例

实现效果图：

如图，使用小程序的scroll-view实现的上拉加载数据，下拉刷新数据，试下代码如下：

js文件代码：

var url = "http://192.168.30.4:8080/gtxcx/carrier/getCarrier.action"; var page = 1; var GetList = function (that) { that.setData({ hidden: false }); wx.request({ url: url, data: { pageSize: 10, pageNo: page }, success: function (res) { var l = that.data.list for (var i = 0; i < res.data.length; i++) { l.push(res.data[i]) } that.setData({ list: l }); page++; that.setData({ hidden: true }); } }); } Page({ data: { hidden: true, list: [], scrollTop: 0, scrollHeight: 0 }, onLoad: function () { var that = this; wx.getSystemInfo({ success: function (res) { console.info(res.windowHeight); that.setData({ scrollHeight: res.windowHeight }); } }); }, onShow: function () { var that = this; GetList(that); }, bindDownLoad: function () { var that = this; GetList(that); }, scroll: function (event) { this.setData({ scrollTop: event.detail.scrollTop }); }, refresh: function (event) { page = 1; this.setData({ list: [], scrollTop: 0 }); GetList(this) }, onPullDownRefresh: function () { console.log("下拉") }, onReachBottom: function () { console.log("上拉"); } })

json文件代码

{ "navigationBarTitleText": "下拉刷新", "enablePullDownRefresh": true, "backgroundTextStyle": "dark" }

wxml文件代码：

{{item.carrierName}} {{item.carrierTelphone}} {{item.carrierId}} 加载中...

wxss文件代码

.container{ height: 100%; padding: 20rpx; } .item{ display: flex; margin-bottom: 50rpx; width:100%; background:#f0f0f0; overflow:hidden; } .img{ height: 100rpx; width: 100rpx; border-radius: 50%; } .text{ display: flex; flex-shrink:1; flex-grow:1; padding: 10rpx; flex-wrap: wrap; font-size: 50rpx; } .title{ font-size: 50rpx; margin:10rpx 100rpx 10rpx 100rpx; } .description{ font-size: 50rpx; align-self:flex-end; }

注意，

http://192.168.30.4:8080/gtxcx/carrier/getCarrier.action这个接口就是更具传入的页数，每次返回不同数据。感谢各位的阅读，以上就是"微信小程序中scroll-view怎么实现上拉加载与下拉刷新"的内容了，经过本文的学习后，相信大家对微信小程序中scroll-view怎么实现上拉加载与下拉刷新这一问题有了更深刻的体会，具体使用情况还需要大家实践验证。这里是，小编将为大家推送更多相关知识点的文章，欢迎关注!
