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。
