本文实例为大家分享了小程序实现分页查询列表的模板,供大家参考,具体内容如下
list.wxml
<view class="home-main"> <!-- 搜索 --> <view class="search-bar"> <view class="search-bar-form"> <image class="search-img" src="https://www.atool.online/images/search-icon.png"></image> <input class="search-input" type="text" placeholder="搜索图片、文章、视频" confirm-type="search"></input> </view> </view> <!-- 列表 --> <view class="classify-list-all"> <view wx:for="{{list}}" wx:key="id" data-item='{{item}}' class="classify-list flex align-center" bindtap="goClassify"> <image class="classify-list-image" src="https://www.atool.online/article/{{item.logo}}"></image> <view class="classify-list-main"> {{item.name}} </view> </view> </view> </view>
list.js
import Api from "../../../config/api"; import Http from "../../../utils/http"; Page({ data: { formData: { size: 10,//分页,一页10条 current: 1,//当前页数 }, isLast: false,//是否是最后一页 list: [],//列表数组 }, onLoad() { //首次请求 this.queryListPage(); }, onPullDownRefresh() { //下拉刷新 this.setData({ 'formData.current': 1 }); this.queryListPage(); }, onReachBottom() { //页面上拉触底事件的处理函数 this.queryListPage(); }, goClassify(e) { wx.navigateTo({ url: `/pages/home/classify/classify?id=${e.currentTarget.dataset.item.id}`, }) }, queryListPage() { //请求列表 if (this.data.isLast) { return; }; Http.request(Api.productQueryMyPage, this.data.formData, 'GET', true).then(res => { let arr = res.data || []; if (arr && arr.length > 0) { arr = arr.map(item => { //需要处理列表 item.name = item.name + '处理后数据'; return item; }); } else { this.setData({ isLast: true, }); } let list = this.data.formData.current === 1 ? arr : this.data.list.concat(arr); let current = this.data.formData.current + 1; this.setData({ list, 'formData.current': current }); }); }, })
api.js
export default { /******* 商品信息 *******/ productQueryMyPage: '/product/queryMyPage',//查询我的商品列表 }
http.js这个简单的封装的一下先凑合用,还不太完善
// import Api from "../config/api"; import Config from "../config/config"; function checkCode(res) { //401token过期 403表示这个接口是需要登录的。你没有权限访问 if ([401, 403].includes(res.statusCode)) { wx.removeStorage({ key: 'token', success() { wx.switchTab({ url: '/pages/my/my-main/my-main' }); } }) } } const http = { request(url, data, method, needLogin) { let header = { 'content-type': 'application/json' // 默认值 }; if (needLogin) { const token = wx.getStorageSync('token'); if (token) { header['Authorization'] = 'Bearer ' + token; } }; return new Promise((resolve, reject) => { wx.request({ url: Config.domain + url, data, method, header, success(res) { console.log(res); console.log(res.data); checkCode(res); resolve(res.data); }, fail(res) { reject(res); } }) }) }, uploadFile(url, filePath, formData, needLogin) { let header: any = { 'content-type': 'multipart/form-data' // 默认值 }; if (needLogin) { const token = wx.getStorageSync('token'); if (token) { header['Authorization'] = 'Bearer ' + token; } }; return new Promise((resolve: any, reject: any) => { wx.uploadFile({ url: Config.domain + url, filePath, name: 'files', formData, header, success(res) { debugger console.log(res); console.log(res.data); checkCode(res.statusCode); resolve(JSON.parse(res.data)); }, fail(res) { reject(res); } }) }) }, }; export default http;
config.js
export default { domain: 'http://www.test.com', }
