本篇文章手把手教你怎么仿做得物APP微信小程序,感兴趣的朋友可以学习了解一下~
![]() 最近正在学习微信小程序开发,也是与两个同学一起合作着手仿做得物APP微信小程序。这里主要分享一下我的学习过程及踩过的一些坑,希望对您有所帮助。 开发准备
总体架构
项目中我负责的部分主要如下(一些数据为固定数据写在 |-config 对应数据
|-assem.js
|-buys.js
|-detail.js
|-kind.js
|-search.js
|-pages
|-buy_page
|-page
|-assem 筛选排序页
|-buy 购买首页
|-detail 商品详情页
|-kinds 品牌分类页
|-produce 鉴别简介页
|-search 搜索页项目规划
参照得物APP微信小程序,下面是我的小程序的tabBar。(有点糙,但是还能看)
"tabBar": {
"selectedColor": "#000000",
"borderStyle": "white",
"backgroundColor": "#fff",
"list": [
{
"text": "购买",
"pagePath": "pages/buy_page/page/buy/buy",
"iconPath": "images/buy.png",
"selectedIconPath": "images/buy_active.png"
},
{
"text": "鉴别查询",
"pagePath": "pages/disting/disting",
"iconPath": "images/disting.png",
"selectedIconPath": "images/disting_active.png"
},
{
"text": "洗护",
"pagePath": "pages/wash/wash",
"iconPath": "images/wash.png",
"selectedIconPath": "images/wash_active.png"
},
{
"text": "我",
"pagePath": "pages/my_page/my/my",
"iconPath": "images/my.png",
"selectedIconPath": "images/my_active.png"
}
]
},云数据库云数据库是一种NoSQL数据库。每一张表是一个集合。 对于我的项目部分,我主要建立了一个商品集合。 dewu_goods 商品表 用于存储创商品的信息
- _id
- amway 是否为推荐
- brand 品牌
- buyer 已购买人数
- ctime 数据创建时间
- digest 详情介绍
- img 详情图
- pic 商品展示图
- kind 种类
- price 价格
- sex 适应人群
- title 简介
- type 首页索引
建立数据集合后需修改数据权限才可正常访问。
可对在数据库中进行这些操作,注意导入数据格式需要是
const db = wx.cloud.database() //云数据库
const dewuCollection = db.collection('dewu') //在js文件中导入数据集合项目解构以下是我主要实现的得物APP小程序界面
接下来对每个页面的细节进行解构。 购买首页
购买首页样式
<view class="page">
<!-- 使用van-sticky设置dewu-hd吸顶 搜索栏-->
<van-sticky>
<!-- dewu-hd使用flex布局 -->
<view class="dewu-hd">

</view>
</van-grid-item>
</van-grid>
</view>
</van-tab>
</van-tabs>
</view>商品项 这个页面布局并不复杂,不过我在写这个布局时还是遇到了坑(感觉是自己跳进去的 我太了)。在做 获取商品项 async onLoad() {
this.proData() //获取推荐数据项
this.shoeData() //获取鞋类数据项
},
proData() {
const {data} = await dewuCollection
.where({
amway: db.command.eq('TRUE')
})
.field({ //获取指定数据项,提升性能
_id:true,
pic:true,
title:true,
buyer:true,
price:true
})
.get()
// console.log(data);
this.setData({
produces: data,
})
}
shoeData() {
let data1 = await dewuCollection
.where({
type: 1
})
.get()
// console.log(data1.data);
this.setData({
shoes: data1.data
})
}绑定详情页 gotoDetail(e) {
// console.log(e);
wx.navigateTo({
url: '/pages/buy_page/page/detail/detail?id='+e.currentTarget.dataset.id,
})
},利用商品 商品详情页
商品详情页样式

</view>
</view>
</view>
</block>
</view>
</view>搜索页面主要分为头部搜索框和内容(搜索推荐,历史记录和搜索到的商品列表)两部分。这里用 搜索记录 async onSearch(e) {
// console.log(e);
if (!e.detail.trim()) {
wx.showToast({
title: '请输入商品名',
})
return
}
let {value, historyList} = this.data

historyList.splice(historyList.indexOf(value), 1)
}
historyList.unshift(value)
this.setData({
historyList
})
wx.setStorageSync('value', historyList)
let keyword = e.detail.trim()
let results = await dewuCollection
.where({

this.getSearchHistory() //获取历史搜索
},
getSearchHistory() {
let historyList = wx.getStorageSync('value')
if(historyList) {
this.setData({

}
},页面加载时从本地 历史搜索 async historySearch(e) {
// console.log(e);
let historyList = this.data.historyList
let value = historyList[e.currentTarget.dataset.index]
this.setData({
value, //修改value
showHotList: false, //隐藏热门搜索
showHistory: false, //隐藏历史搜索
results: [] //清空商品列表
})
},点击历史搜索项时 清空控件 onClear() {
this.setData({
results: [],
value: '',
showHotList: true,
showHistory: true

},
onChange(e) { //search框输入改变时实时修改数据
// console.log(e.detail);
this.setData({

分类页样式
<view class="page">

</view>
<van-grid>
<van-grid-item>{{}}</van-grid-item>
</van-grid>
</view>
</scroll-view>
</view>
</view>
</view>分类页面主要是使用了 初始化品类 onLoad: function (options) {
this.setData({
kindNav: kindNav,
kindall: kindItem,
// console.log(this.data.kindall);
let kinds=[];
// console.log(this.data.kindall)
this.data.kindall.forEach(kind => { //循环从所有品类中获取对应kindNav的并存入数组中
if(kind.camptype == 0) {
kinds.push(kind)
}
})
this.setData({
kindItem: kinds,
})
}, )
},选择分类 changeKinds(e) {
console.log(e);
let {index, type} = e.currentTarget.dataset;
console.log(index, type);//index与推荐品牌的索引有关。type与kind.js的camptype有关
this.setData({
activeNavIndex: index,
})
let title=[]
this.data.kindTitles.forEach(kindTitle => {
if(index == kindTitle.titletype) {
title.push(kindTitle)
}
})
this.setData({
kindItem: kinds,
})
},绑定筛选页 gotoAssem(e) {
// console.log(e); 利用kind属性值唯一(buy页面tabs的title)
wx.navigateTo({
url: '/pages/buy_page/page/assem/assem?title='+e.currentTarget.dataset.title,
})
},筛选排序页

</van-popup>这里使用 初始商品排序 async onLoad(options) {
// console.log(options);
let title = options.title
let data1 = await dewuCollection
.where({
kind: title //绑定跳转时(kind唯一)获取对应数据
})
.get()
// console.log(data1);
this.setData({
goods: data1.data,
titles: title
})
},基本排序 async changeItem(e) {
// console.log(e);
let index = e.currentTarget.dataset.index //index对应排序方式
this.setData({
activeTabIndex: index
})
// console.log(index);
if(index == 1) { //销量排序
await dewuCollection
.where({
kind: this.data.titles
})
.orderBy('buyer', 'desc')
.get()
.then(res => {
this.setData({
goods: res.data,
index: index
})
// console.log(this.data.index);
})
}
if(index == 0) { //综合排序
await dewuCollection
.where({
kind: this.data.titles
})
.get()
.then(res => {
this.setData({

})
}
if(index == 2 && this.data.flag == -1) { //价格降序排序
await dewuCollection
.where({

},设置一个flag属性默认值为-1, 筛选排序 pick(e) {
let flag = e.currentTarget.dataset.flag
let index = e.currentTarget.dataset.index
let cd = this.data.human[index].kind
if(flag==index) {

flag3: -1,
activeIndex3: -1,
cd1: '',
cd2: '',
cd3: 0,
cd4: 10000000,
})
},这里有一个坑是,不可在 确认筛选 async ischeck() { //点击确定按钮进行筛选显示结果
let cd3 = Number(this.data.cd3)
let cd4 = Number(this.data.cd4)==0?1000000:Number(this.data.cd4)
let index = Number(this.data.index)
if(this.data.cd1!='' && this.data.cd2!=''){
await dewuCollection
.where({
kind: this.data.titles,
sex: this.data.cd1,
brand: this.data.cd2,
price: _.gt(cd3).and(_.lt(cd4)),

.get()
.then(res => {
