黑马商城实战项目
项目搭建
-
利用HBuilder X创建基本项目结构
-
运行项目
-
整理基本项目结构，并修改窗口外观
"globalStyle": { "navigationBarTextStyle": "white", "navigationBarTitleText": "黑马商城", "navigationBarBackgroundColor": "#1989fa", "backgroundColor": "#F8F8F8" }
配置tabbar
-
创建tabbar对应的四个页面和图标准备好
-
将页面路径配置到pages.json中的pages数组中
"pages": [ //pages数组中第一项表示应用启动页，参考：https://uniapp.dcloud.io/collocation/pages { "path": "pages/index/index" }, { "path": "pages/member/member" }, { "path": "pages/cart/cart" }, { "path": "pages/search/search" } ] -
配置tabbar
{ "tabBar": { "list": [ { "pagePath":"pages/index/index", "text":"首页", "iconPath":"static/icon/home.png", "selectedIconPath":"static/icon/home-active.png" }, { "pagePath":"pages/member/member", "text":"会员", "iconPath":"static/icon/member.png", "selectedIconPath":"static/icon/member-active.png" }, { "pagePath":"pages/cart/cart", "text":"购物车", "iconPath":"static/icon/cart.png", "selectedIconPath":"static/icon/cart-active.png" }, { "pagePath":"pages/search/search", "text":"搜索", "iconPath":"static/icon/search.png", "selectedIconPath":"static/icon/search-active.png" } ] } }
获取轮播图数据
-
封装uni.request请求，并挂在到全局
-
创建util》api.js
// 封装get请求 const baseUrl = "http://localhost:8082" export const myRequest = (options)=>{ return new Promise((resolve,reject)=>{ uni.request({ method: options.method, data: options.data, url: baseUrl+options.url, success(res) { if(res.data.status !== 0) { return uni.showToast({ title: '获取数据失败' }) } resolve(res) }, fail(err) { uni.showToast({ title: '获取数据失败' }) reject(err) } }) }) } -
在main.js中导入并挂载到全局
import { myRequest } from './util/api.js' Vue.prototype.$myRequest = myReques
-
-
获取轮播图的数据
-
定义获取轮播图的方法
methods: { async getSwipers () { const res = await this.$myRequest({ method: 'GET', url: '/api/getlunbo' }) this.swipers = res.data.message } } -
在onLoad中调用该方法
this.getSwipers()
-
实现轮播图的结构和数据渲染
-
定义轮播图的基本结构
<swiper class="swiper" indicator-dots :autoplay="true" :interval="2000" circular> <swiper-item v-for="item in swipers" :key="item.id"> <image :src="item.img"></image> </swiper-item> </swiper> -
样式，在工具中安装scss
<style lang="scss"> .home{ swiper{ height: 380rpx; image{ width: 750rpx; height: 380rpx; } } } </style>
实现菜单导航结构

获取数据
-
定义获取数据的方法
// 获取推荐商品 async getGoods () { const res = await this.$myRequest({ url: '/api/getgoods?pageindex=1' }) this.goods = res.data.message } -
在onLoad生命周期中调用该方法
this.getGoods()
渲染数据
-
通过v-for渲染数据
<view class="hot_goods"> <view class="tit">推荐商品</view> <!-- 一般用法 --> <view class="goods_list"> <view class="goods_item" v-for="item in goods" :key="item.id"> <image :src="item.img_url"></image> <view class="price"> <text>{{item.sell_price}}</text> <text>{{item.market_price}}</text> </view> <view class="name">{{item.title}}</view> </view> </view> </view>
完成黑马超市页面
改造导航菜单
-
定义数据
navs: [ { icons: "iconfont icon-ziyuan", title: "黑马超市", path: "/pages/goods/list" }, { icons: "iconfont icon-tupian", title: "社区图片", path: "/pages/pics/pics" }, { icons: "iconfont icon-guanyuwomen", title: "联系我们", path: "/pages/contact/contact" }, { icons: "iconfont icon-shipin", title: "学习视频", path: "/pages/videos/videos" } ] -
渲染数据
<view class="nav"> <view class="item" v-for="(item,index) in navs" :key="index"> <view :class="item.icons"></view> <text>{{item.title}}</text> </view> </view> -
给导航菜单注册点击事件
<view class="goods_item" v-for="item in goods" :key="item.id"> -
定义跳转的方法
goNavigator (url) { uni.navigateTo({ url }) }
创建黑马超市页面
- 创建页面，goods>list.vue
- 将页面路劲配置到pages文件中，修改标题
封装商品列表组件
-
在components下面创建goods>list.vue
<template> <view class="goods_list"> <view class="goods_item" v-for="item in goods" :key="item.id"> <image :src="item.img_url"></image> <view class="price"> <text>{{item.sell_price}}</text> <text>{{item.market_price}}</text> </view> <view class="name">{{item.title}}</view> </view> </view> </template> <script> export default { props:{ goods:Array } } </script> <style lang="scss"> .goods_list { display: flex; padding: 0 15rpx; justify-content: space-between; overflow: hidden; flex-wrap: wrap; .goods_item { width: 355rpx; margin-bottom: 15rpx; background: #fff; padding: 10px; box-sizing: border-box; image{ height: 150px; width: 150px; display: block; margin: 10px auto; } .price{ font-size: 18px; color: red; padding: 8px 0; text:nth-child(2){ color: #ccc; text-decoration: line-through; margin-left: 10px; font-size: 13px; } } .name { font-size: 14px; } } } </style> -
在首页引入该组件
import goodsList from "../../components/goods-list/index.vue" components: { "goods-list":goodsList } -
使用组件并将数据传递到组件内部
<goods-list :goods="goods"></goods-list>
渲染商品列表
-
定义获取商品列表数据的方法并调用
<script> export default { data () { return { goods: [] } }, methods: { async getGoods () { const res = await this.$myRequest({ url: '/api/getgoods?pageindex=1' }) this.goods = res.data.message }, }, onLoad () { this.getGoods() } } </script> -
引入商品组件并使用
<template> <view class="goods_list"> <goods-list :goods="goods"></goods-list> </view> </template> <script> import goodsList from "../../components/goods-list/index.vue" export default { components: { "goods-list": goodsList } } </script>
实现上拉加载更多
-
通过onReachBottom来监听触底
onReachBottom () { this.pageindex++ this.getGoods() } -
修改给goods赋值
this.goods = [...this.goods,...res.data.message] -
动态显示底线
-
通过onReachBottom监听是否还有更多
if(this.pageindex*10>this.goods.length) return this.flag = true -
通过v-if控制底线
<view class="over_line" v-if="flag">----------我是有底线的----------</view>
-
实现下拉刷新
-
通过onPullDownRefresh进行下拉刷新的操作
onPullDownRefresh() { this.goods = [] this.pageindex = 1 this.flag = false setTimeout(()=>{ this.getGoods(()=>{ uni.stopPullDownRefresh() }) },1000) }

封装为组件
创建news-item.vue
<template>
<view>
<view class="news_item" v-for="item in data" :key="item.id">
<image :src="item.img_url"></image>
<view class="content">
<view class="tit">{{item.title}}</view>
<view class="info">

<script>
export default {
props: ['data'],
filters:{
formatDate(data){
const date = new Date(data)
console.log(date)
const day = date.getMonth().toString().padStart(2,'0')+'-'+date.getDay().toString().padStart(2,'0')
return date.getFullYear()+'-'+day
}
}
}
