微信小程序开发(6)：一个业务页面的完成

github地址：https://github.com/yexiaochai/wxdemo

我们首页功能基本完成，我对比了下实际工作中的需求，完成度有70%以上，如果再花一两天时间，便能跟之前工作做的差不多了，今天我们继续实现一个页面列表，便结束这次的学习，后面几天要出差，所以总结性的文章本周未必能出来，静待下周吧。

这里考虑demo复杂度，列表页功能完成度也仅仅完成主功能模块，与真实工作完成度对比60%左右吧，于是我们开始愉快的代码，首先是将我们的页面样式实现：

<view class="page-wrapper ">   <view class="bus-list js_bus_list ">     <view data-supplierid="100020" data-key="" class="bus-list-item  ">       <view class="bus-time"> 08:25</view>       <view class="tobooking"> 预订 </view>       <view class="detail">         <view class="detail1">           <view class="start">             <text class="icon-circle s-icon1"></text>东莞市南城汽车客运站</view>           <view class="end">             <text class="icon-circle s-icon2"></text>连州</view>         </view>         <view class="tags">           <view>             <text class="price">￥135</text>           </view>           <view>             <text class="countleft">10张</text>           </view>           <view>             <text class="b-tags js_tags"></text>           </view>         </view>       </view>     </view>   </view>   <view class="bus-list js_bus_list ">     <view data-supplierid="100020" data-key="" class="bus-list-item  ">       <view class="bus-time"> 08:25</view>       <view class="tobooking"> 预订 </view>       <view class="detail">         <view class="detail1">           <view class="start">             <text class="icon-circle s-icon1"></text>东莞市南城汽车客运站</view>           <view class="end">             <text class="icon-circle s-icon2"></text>连州</view>         </view>         <view class="tags">           <view>             <text class="price">￥135</text>           </view>           <view>             <text class="countleft">10张</text>           </view>           <view>             <text class="b-tags js_tags"></text>           </view>         </view>       </view>     </view>   </view>   <view class="bus-list js_bus_list ">     <view data-supplierid="100020" data-key="" class="bus-list-item  ">       <view class="bus-time"> 08:25</view>       <view class="tobooking"> 预订 </view>       <view class="detail">         <view class="detail1">           <view class="start">             <text class="icon-circle s-icon1"></text>东莞市南城汽车客运站</view>           <view class="end">             <text class="icon-circle s-icon2"></text>连州</view>         </view>         <view class="tags">           <view>             <text class="price">￥135</text>           </view>           <view>             <text class="countleft">10张</text>           </view>           <view>             <text class="b-tags js_tags"></text>           </view>         </view>       </view>     </view>   </view>   <include src="../mod/calendar.wxml" />   <include src="../../utils/abstract-page.wxml" /> </view>

.page-wrapper {     margin: 0;     font-size: 28rpx;     line-height: 1.5;     color: #333;     background-color: #efefef;     overflow-x: hidden;     -webkit-overflow-scrolling: touch;     -webkit-tap-highlight-color: transparent;     min-height:2000rpx; } .bus-list .bus-list-item { position: relative; height: 160rpx; background-color: #fff; margin: 16rpx 0; border: 2rpx solid #e5e5e5; border-width: 2rpx 0; } .bus-list .bus-list-item::before,.bus-list .bus-list-item::after { position: absolute; left: 122rpx; content: ''; width: 24rpx; height: 12rpx; background-color: #efefef; border: 2rpx solid #e5e5e5; } .bus-list .bus-list-item::before {   border-radius: 0 0 60rpx 60rpx;     border-top: none;   top: -2rpx; } .bus-list .bus-list-item::after {   border-radius: 60rpx 60rpx 0 0;     border-bottom: none;   bottom: -2rpx; } .bus-list .bus-list-item .bus-time { position: absolute; left: 0; width: 134rpx; height: 100rpx; line-height: 100rpx; margin: 30rpx 0; color: #00b358; text-align: center; font-size: 40rpx; font-family: Arial; border-right: 2rpx dashed #e5e5e5; } .bus-list .bus-list-item .tobooking { background-color: #00B358; position: absolute; right: 0; width: 120rpx; height: 160rpx; line-height: 160rpx; text-align: center; color: #fff; font-size: 30rpx; } .bus-list .bus-list-item.disabled .tobooking {   background-color: #c5c5c5; } .bus-list .bus-list-item .detail { height: 80rpx; padding: 36rpx 0; margin: 0 140rpx 0 144rpx; } .bus-list .bus-list-item .detail  .sub-list{     height: 52rpx; } .bus-list .bus-list-item .start, .bus-list .bus-list-item .end { color: #333333; font-size: 26rpx; } .bus-list .bus-list-item .price { font-family: Arial; color: #fd8f01; font-size: 32rpx; font-weight: 600; } .bus-list .bus-list-item.disabled .ticket { display: none; } .bus-list .bus-list-item .ticket {   color: #fd8f01;   font-size: 24rpx;   border: 2rpx solid #fd8f01;   padding: 2rpx 8rpx;   border-radius: 10rpx;   font-family: Arial; } .bus-list .bus-list-item.disabled .ticket {   color: #c5c5c5; } .bus-list .bus-list-item .s-icon1 {   margin: 0 10rpx;   border-color: #00B358; } .bus-list .bus-list-item .s-icon2 {   margin: 0 10rpx;   border-color: #f06463; } .bus-list .bus-list-item .tags {     width: 160rpx;     text-align: right;     position: absolute;     right: 0;     margin-right: 138rpx;     margin-top: 34rpx;     top: 0; }

轻轻松松完成了页面主体布局：

然后这里需求请求数据，所以我们去设置一个请求实体：

class ListModel extends DemoModel {   constructor() {     super();     this.url = '/schedule/list';   } } module.exports = {   cityModel: new CityModel,   city2Model: new City2Model,   listModel: new ListModel }

开始请求参数：

onLoad: function (data) {     let scope = this;     if(!data || !data.sid || !data.aid || !data.date) {       this.showToast('参数错误');       return     }     this.index = 0;     let listModel = models.listModel;     listModel.setParam({       startcityid: data.sid,       arrivalcityid: data.aid,       startdatetime: data.date / 1000,       page: this.index + 1     });     this.showLoading();     listModel.execute(function(data) {       scope.hideLoading();       scope._appendList(data.schedules);     });   }

接下来的工作便是渲染页面即可，如果不考虑细节，只是做demo，真的很轻易呢：）

//获取公共ui操作类实例 const _page = require('../../utils/abstract-page.js'); let modCalendar = require('../mod/calendar.js'); const models = require('../../data/demo-model.js') const util = require('../../utils/util.js') //获取应用实例 const app = getApp() Page(_page.initPage({   data: {     listData: []   },   // methods: uiUtil.getPageMethods(),   methods: {   },   goIndex: function () {     wx.navigateTo({       url: '../index/index'     })   },   onShow: function () {     global.sss = this;     let scope = this;   },   _appendList: function (data) {     for(let i = 0, len = data.length; i < len; i++) {       data[i].dateStr = util.dateUtil.format(new Date(data[i].datetime * 1000), 'H:F' )     }     this.setData({       listData: this.data.listData.concat(data)     });   },   onLoad: function (data) {     let scope = this;     if(!data || !data.sid || !data.aid || !data.date) {       this.showToast('参数错误');       return     }     this.index = 0;     let listModel = models.listModel;     listModel.setParam({       startcityid: data.sid,       arrivalcityid: data.aid,       startdatetime: data.date / 1000,       page: this.index + 1     });     this.showLoading();     listModel.execute(function(data) {       scope.hideLoading();       scope._appendList(data.schedules);     });   } }, {   modCalendar: modCalendar }))

<view class="page-wrapper ">   <view class="calendar-bar-wrapper js_calendar_wrapper">     <view class="bus-tabs calendar-bar">       <view class="tabs-item js_pre_day">前一天</view>       <view class="tabs-item js_show_calendar" style="-webkit-flex: 2; flex: 2;">2018-8-6 周一(明天)</view>       <view class="tabs-item js_next_day">后一天</view>     </view>   </view>   <view class="bus-list js_bus_list ">     <block wx:for="{{listData}}" wx:key="k">       <view class="bus-list-item  ">         <view class="bus-time">{{item.dateStr}}</view>         <view class="tobooking"> 预订 </view>         <view class="detail">           <view class="detail1">             <view class="start">               <text class="icon-circle s-icon1"></text>{{item.startstationname}}</view>             <view class="end">               <text class="icon-circle s-icon2"></text>{{item.arrivalstationname}}</view>           </view>           <view class="tags">             <view>               <text class="price">￥{{item.price / 100}}</text>             </view>             <view>               <text class="countleft">{{item.cansellcountamount}}张</text>             </view>             <view>               <text class="b-tags js_tags"></text>             </view>           </view>         </view>       </view>     </block>   </view>   <include src="../mod/calendar.wxml" />   <include src="../../utils/abstract-page.wxml" />   <view class="bus-list js_bus_list " ontap="goIndex">     去首页   </view> </view>

最后，我们完善一下这里日期相关操作，便暂时结束这次学习：

列表页的一些总结

我们做小程序相关学习有快两周了，完成了一个简单的demo，项目还是有一定复杂度，感觉上还是比较适合做小程序了解的，但是也有一些问题，比如写到后面事实上更多是业务的东西了，业务会涉及很多细节体验，需要耗时费力，比如今天的列表业务，显然就偷懒了，代码质量也没怎么关注，事实上大家可以思考一些问题，这里还差很多功能：

① 滚动加载

② 列表各种状态

③ ……

事实上，列表页是常用的一种业务页面，虽然各种列表页的筛选条件不一样，但是主体功能无非都是：

① 列表渲染

② 滚动加载

③ 条件筛选、重新渲染

所以说我们其实可以将其做成一个页面基类，跟abstract-page一个意思，这里留待我们下次来处理吧，借此我们微信小程序的学习教程就此结束，我后面几天总结下前面所学整理一个博客出来，帮助各位更好的了解。
