微信小程式scroll-view實作上拉加載與下拉刷新的實例
實現效果圖:
如圖,使用小程式的scroll-view實現的上拉載入數據,下拉刷新數據,試下程式碼如下:
js檔案程式碼:
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檔案程式碼
{ "navigationBarTitleText": "下拉刷新", "enablePullDownRefresh": true, "backgroundTextStyle": "dark" }
wxml檔案程式碼:
<view class="container"> <scroll-view scroll-top="{{scrollTop}}" scroll-y="true" style="height:{{scrollHeight}}px;" class="list" bindscrolltolower="bindDownLoad" bindscroll="scroll" bindscrolltoupper="refresh"> <view class="item" wx:for="{{list}}"> <image class="img" src="https://cdn.kuaidi100.com/images/all/56/zhongtong.png"></image> <view class="text"> <text class="title">{{item.carrierName}}</text> <text class="description">{{item.carrierTelphone}}</text> <text class="description">{{item.carrierId}}</text> </view> </view> </scroll-view> <view class="body-view"> <loading hidden="{{hidden}}" bindchange="loadingChange"> 加载中... </loading> </view> </view>
#wxss檔案代碼

.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。#########以上就是本文的全部內容,希望對大家的學習有所幫助,更多相關內容請關注PHP中文網! ######相關推薦:#########微信小程式清單的上拉載入和下拉刷新的實作############微信小程式實作點擊按鈕修改字體顏色的功能###################
