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：

}
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
}))

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
