微信小程序开发07-列表页面怎么做

接上文： 微信小程序开发06-一个业务页面的完成

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：

 1 <view class="page-wrapper ">
 2   <view class="bus-list js_bus_list ">
 3     <view data-supplierid="100020" data-key="" class="bus-list-item  ">
 4       <view class="bus-time"> 08:25view>
 5       <view class="tobooking"> 预订 view>
 6       <view class="detail">
 7         <view class="detail1">
 8           <view class="start">

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：

 1 class ListModel extends DemoModel {
 2   constructor() {
 3     super();
 4     this.url = '/schedule/list';
 5   }
 6 }
 7 
 8 module.exports = {
 9   cityModel: new CityModel,
10   city2Model: new City2Model,
11   listModel: new ListModel
12 
13 }

开始请求参数：

 1 onLoad: function (data) {
 2     let scope = this;
 3 
 4     if(!data || !data.sid || !data.aid || !data.date) {
 5       this.showToast('参数错误');
 6       return
 7     }
 8 
 9     this.index = 0;
10     let listModel = models.listModel;
11 
12     listModel.setParam({
13       startcityid: data.sid,
14       arrivalcityid: data.aid,
15       startdatetime: data.date / 1000,
16       page: this.index + 1
17     });
18 
19     this.showLoading();
20     listModel.execute(function(data) {
21       scope.hideLoading();
22       scope._appendList(data.schedules);
23 
24     });
25 
26   }

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：）

 1 //获取公共ui操作类实例
 2 const _page = require('../../utils/abstract-page.js');
 3 let modCalendar = require('../mod/calendar.js');
 4 const models = require('../../data/demo-model.js')
 5 const util = require('../../utils/util.js')
 6 
 7 //获取应用实例
 8 const app = getApp()
 9 
10 Page(_page.initPage({
11   data: {
12     listData: []
13   },
14   // methods: uiUtil.getPageMethods(),
15   methods: {
16   },
17 
18   goIndex: function () {
19 
20     wx.navigateTo({
21       url: '../index/index'
22     })
23   },
24   onShow: function () {
25     global.sss = this;
26     let scope = this;
27   },
28 
29   _appendList: function (data) {
30 
31     for(let i = 0, len = data.length; i < len; i++) {
32       data[i].dateStr = util.dateUtil.format(new Date(data[i].datetime * 1000), 'H:F' )
33     }
34 
35     this.setData({
36       listData: this.data.listData.concat(data)
37     });
38   },
39 
40   onLoad: function (data) {
41     let scope = this;
42 
43     if(!data || !data.sid || !data.aid || !data.date) {
44       this.showToast('参数错误');
45       return
46     }
47 
48     this.index = 0;
49     let listModel = models.listModel;
50 
51     listModel.setParam({
52       startcityid: data.sid,
53       arrivalcityid: data.aid,
54       startdatetime: data.date / 1000,
55       page: this.index + 1
56     });
57 
58     this.showLoading();
59     listModel.execute(function(data) {
60       scope.hideLoading();
61       scope._appendList(data.schedules);
62 
63     });
64 
65   }
66 }, {
67   modCalendar: modCalendar
68 }))

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
