- 封装接口 :
api/product.js
// 获取商品详情数据
export const getProDetail = (goodsId) => {
return request.get('/goods/detail', {
params: {
goodsId
}
})
}
// 获取商品评价
export const getProComments = (goodsId, limit) => {
return request.get('/comment/listRows', {
params: {
goodsId,
limit
}
})
}
- 动态路由,获取参数
这样就在detail里存好了:

加入购物车——唤起弹层
- 导入动作面板(弹层)的组件
import Vue from 'vue'
import { ActionSheet } from 'vant'
Vue.use(ActionSheet)
- 页面中
<div @click="addFn" class="btn-add">加入购物车</div>
<div @click="buyFn" class="btn-buy">立刻购买</div>
</div>
<!-- 加入购物车的弹层 -->
<!-- 弹层v-model -->
<van-action-sheet v-model="showPannel" title="加入购物车">
<div class="content">内容</div>
</van-action-sheet>
- 方法
showPannel: false // 控制弹层的显示
// 加入购物车
addFn () {
this.showPannel = true
},
// 购买商品
buyFn () {
this.showPannel = true
}
! 这里有个小逻辑点:你现在给"加入购物车"和“立即购买”都添加了相同的vant组件,所以标题是一样的
但是我们并不想让他们一样,所以 思路 就是:
- 在data中增加一个变量:去标记弹层的状态
mode: 'cart' // 标记弹层状态- 默认设置成了cart
- 在两个方法处对这个mode变量进行修改
- 通过
this.mode = 'cart'
- 通过
// 加入购物车
addFn () {
this.mode = 'cart'
this.showPannel = true
},
// 购买商品
buyFn () {
this.mode = 'buyNow'
this.showPannel = true
}
}
- 最后在页面上进行修改
- 给title了一个小逻辑:
:title="mode==='cart'?'加入购物车':'立即购买'"
- 给title了一个小逻辑:
<van-action-sheet v-model="showPannel" :title="mode==='cart'?'加入购物车':'立即购买'">
<div class="content">内容</div>
</van-action-sheet>
- 弹窗动态渲染
- 首先先把静态结构写好
<van-action-sheet v-model="showPannel" :title="mode === 'cart' ? '加入购物车' : '立刻购买'">
<div class="product">
<div class="product-title">
<div class="left">
<img src="http://cba.itlike.com/public/uploads/10001/20230321/8f505c6c437fc3d4b4310b57b1567544.jpg" alt="">
</div>
<div class="right">
<div class="price">
<span>¥</span>
<span class="nowprice">9.99</span>
</div>
<div class="count">
<span>库存</span>
<span>55</span>
</div>
</div>
</div>
<div class="num-box">
<span>数量</span>
数字框占位
</div>
<div class="showbtn" v-if="true">
<div class="btn" v-if="true">加入购物车</div>
<div class="btn now" v-else>立刻购买</div>
</div>
<div class="btn-none" v-else>该商品已抢完</div>
</div>
</van-action-sheet>
//样式
.product {
.product-title {
display: flex;
.left {
img {
width: 90px;
height: 90px;
}
margin: 10px;
}
.right {
flex: 1;
padding: 10px;
.price {
font-size: 14px;
color: #fe560a;
.nowprice {
font-size: 24px;
margin: 0 5px;
}
}
}
}
.num-box {
display: flex;
justify-content: space-between;
padding: 10px;
align-items: center;
}
.btn, .btn-none {
height: 40px;
line-height: 40px;
margin: 20px;
border-radius: 20px;
text-align: center;
color: rgb(255, 255, 255);
background-color: rgb(255, 148, 2);
}
.btn.now {
background-color: #fe5630;
}
.btn-none {
background-color: #cccccc;
}
}
- 然后再对页面进行动态渲染,并添加一些需要的v-if判断
<!-- 加入购物车的弹层 -->
<!-- 弹层v-model -->
<van-action-sheet v-model="showPannel" :title="mode==='cart'?'加入购物车':'立即购买'">
<div class="product">
<div class="product-title">
<div class="left">
<img :src="detail.goods_image">
</div>
<div class="right">
<div class="price">
<span>¥</span>
<span class="nowprice">{{ detail.goods_price_min }}</span>
</div>
<div class="count">
<span>库存</span>
<span>{{ detail.stock_total }}</span>
</div>
</div>
</div>
<div class="num-box">
<span>数量</span>
数字框占位
</div>
<!-- 有库存才显示按钮,不然就是显示已抢完 -->
<div class="showbtn" v-if="detail.stock_total>0">
<div class="btn" v-if="mode==='cart'">加入购物车</div>
<div class="btn now" v-else>立刻购买</div>
</div>
<div class="btn-none" v-else>该商品已抢完</div>
</div>
</van-action-sheet>
加入购物车——封装数字框组件
为什么要封装成组件?
因为你不仅在加入购物车这个商品详情页使用,等写到后面的购物车界面时你也需要这个组件,所以我们这里选择把它封装成一个通用的组件
- 封装组件
- 实现加减号修改数字(利用
v-model——>:value和@input)
父传子
<CountBox v-model="addCount"></CountBox>
import CountBox from '@/components/CountBox.vue'
addCount: 1 // 数字框绑定的数据
//————————————————————————————
props: {
value: {
type: Number,
default: 1
}
}
子传父
<button @click="handleSub" class="minus">-</button>
<input :value="value" class="inp" type="text" >
<button @click="handleAdd" class="add">+</button>
methods: {
handleSub () {
if (this.value <= 1) {
return
}
this.$emit('input', this.value - 1)
},
handleAdd () {
this.$emit('input', this.value + 1)
}
}
- 继续完善——使得在输入框内输入也可以修改到值
这里有个小知识点:
@change="handleChange"再配合下面的handleChange函数意思是当你在输入框里回车时,可以拿到数据
handleChange (e) {
const num = +e.target.value // 转数字处理 : 1. 会被转成数字 2. 被转成NAN
// 当输入了不合法的文本或者输入了负值
if (isNaN(num) || num < 1) {
e.target.value = this.value
return
}
this.$emit('input', num)
}
加入购物车——判断token添加登录提示
1. 给按钮添加点击事件,然后写方法
方法中:
- 判断token是否存在
!this.$store.getters.token
- 1.如果token不存在,弹确认框
- 2.如果token存在,继续请求操作
导入vant提示框组件
import { Dialog } from 'vant'
Vue.use(Dialog)
<div @click="addCart" class="btn" v-if="mode==='cart'">加入购物车</div>
addCart () {
// 因为token设置在全局,所以直接全局访问token
if (!this.$store.getters.token) {
// 弹确认框
this.$dialog.confirm({
title: '温馨提示',
message: '亲此时需要先登录再操作哈',
confirmButtonText: '去登录',
cancelButtonText: '再逛逛'
})
.then(() => {
this.$router.push('/login')
})
.catch(() => {})
return
}
console.log('正常登录')
}
2. 但是现在有一个问题:就是我们在跳转到登录页面然后完成登录后,系统会再自动跳回首页。但是我们是想要在登录之后,可以再回到我们刚刚选的商品的详情页
这就说明,在我们跳转时是需要传参的(带查询参数的用的是fullpath,不带参数的是path)
// prodetail/index.js
.then(() => {
// this.$route.fullpath(包含查询参数)
this.$router.replace({
path: '/login',
query: {
backUrl: this.$route.fullPath
}
})
})
然后在登录页面 login/index.js 里进行判断
- 进行判断,看地址栏有无回跳地址
- 如果有 => 说明是其他页面,拦截到登录来的,需要回跳
- 如果没有=> 正常去首页
// 在提示登录成功下面写
const url = this.$route.query.backUrl || '/'
// this.$router.push(url)
this.$router.replace(url)
3. 回跳处理
这里还有一个知识点:就是这里需要把push改成replace
- 用push——因为当你登录完回到详情页后如果此时点返回,用push的话就回回到你上一个页面也就是登录页面
- 用replace——用replace的话就可以返回到商品列表页或者首页了(原理就是replace不是跳转到一个新页面,而是新页面覆盖掉现在的页面)
加入购物车——封装接口进行请求
目标:封装接口,进行加入购物车的请求
api/cart.js
import request from '@/utils/request'
// 加入购物车
// goodsId => 商品id iphone8
// goodsSkuId => 商品规格id 红色的iphone8 粉色的iphone8
export const addCart = (goodsId, goodsNum, goodsSkuId) => {
return request.post('/cart/add', {
goodsId,
goodsNum,
goodsSkuId
})
}
prodetail/index.js
import {addCart} from '@/api/cart'
// ————————————————————在这里
const res = await addCart(this.goodsId, this.addCount, this.detail.skuList[0].goods_sku_id)
console.log(res)
这个addCart接口,还有两个参数,但是我们把它写到全部的请求里,因为不仅这个加入购物车这里要使用
——————————然后
- 准备小图标,然后把carttotal渲染出来
<div class="icon-cart">
<span v-if="cartTotal > 0" class="num">{{ cartTotal }}</span>
<van-icon name="shopping-cart-o" />
<span>购物车</span>
</div>
.footer .icon-cart {
position: relative;
padding: 0 6px;
.num {
z-index: 999;
position: absolute;
top: -2px;
right: 0;
min-width: 16px;
padding: 0 4px;
color: #fff;
text-align: center;
background-color: #ee0a24;
border-radius: 50%;
}
}
cartTotal: 0
// ————————————————————在这里
const { data } = await addCart(this.goodsId, this.addCount, this.detail.skuList[0].goods_sku_id)
this.cartTotal = data.cartTotal
还还还有一个首页和购物车的跳转——————
@click="$router.push('/')
@click="$router.push('/cart')
购物车

2. 构建vuex cart模块,api 发请求获取数据存储
1.构建cart模块
export default {
namespaced: true,
state () {
return {
cartList: []
}
},
mutations: {},
actions: {},
getters: {}
}
记得这个模块构建之后,要在index.js上挂载:import cart from './modules/cart'
2.在cart.js里加上“获取购物车列表”的api接口
// 获取购物车列表
// 这是异步获取请求的操作
export const getCartList = () => {
return request.get('/cart/list')
}
3. 在cart模块里调一下
actions: {
async getCartAction () {
// 调一下我们刚刚封装好的方法
const res = await getCartList()
console.log(res)
}
},
4. 在cart.vue页面调用
created () {
// !!!必须时登录过的用户!!!,才有用户购物车列表
if (this.$store.getters.token) {
this.$store.dispatch('cart/getCartAction')
}
}
5. 这样就可以获取得到购物车列表信息了,得到后就可以对res解构了
即在module/cart.js里解构,设置
这里面还有一个关于商品前面“复选框”的维护
mutations: {
// 解构出data后,我们需要把data.list存起来
// 而存起来就需要提供对应的mutation了
// 提供一个设置我们cartList的mutation
setCartList (state, newList) {
state.cartList = newList
}
},
actions: {
async getCartAction (context) {
// 调一下我们刚刚封装好的方法
const { data } = await getCartList()
// 后台返回的数据中,不包含复选框的选中状态,为了实现将来的功能
// 需要手动维护数据,给每一项添加一个isChecked状态(标记当前商品是否选中)
data.list.forEach(item => {
item.isChecked = true
})
// 调用mutation
context.commit('setCartList', data.list)
}
},
3. 基于数据 动态渲染 购物车列表
如果我们要做动态渲染,数据已经告诉我们存在于vuex里,我们在页面中想要拿到这个state中的数据,怎么办呢??
——我们可以提供coputed计算属性
这里还需要辅助函数进行映射——拿到我们的状态
映射👇
import {mapState} from 'vuex'
computed:{
...mapState('cart',['cartList'])
}
然后页面就可以开始渲染了
<template>
<div class="cart">
<van-nav-bar title="购物车" fixed />
<!-- 购物车开头 -->
<div class="cart-title">
<span class="all">共<i>4</i>件商品</span>
<span class="edit">
<van-icon name="edit" />
编辑
</span>
</div>
<!-- 购物车列表 -->
<div class="cart-list">
<div class="cart-item" v-for="items in cartList" :key="items.goods_id">
<van-checkbox @click="toggleCheck(items.goods_id)" :value="items.isChecked"></van-checkbox>
<div class="show">
<img :src="items.goods.goods_image">
</div>
<div class="info">
<span class="tit text-ellipsis-2">{{ items.goods.goods_name }}</span>
<span class="bottom">
<div class="price">¥ <span>{{ items.goods.goods_price_min }}</span></div>
<!-- 既希望保留原本的形参,又需要通过调用函数传参 => 箭头函数包装一层 -->
<CountBox :value="items.goods_num"></CountBox>
</span>
</div>
</div>
</div>
<div class="footer-fixed">
<div class="all-check">
<van-checkbox icon-size="18"></van-checkbox>
全选
</div>
<div class="all-total">
<div class="price">
<span>合计:</span>
<span>¥ <i class="totalPrice">99.99</i></span>
</div>
<div v-if="true" class="goPay">结算(5)</div>
<div v-else class="delete">删除</div>
</div>
</div>
</div>
</template>
4. 封装getters实现动态统计
store/module/cart.js
getters: {
// 求所有的商品累加总数
cartTotal (state) {
// reduce(() => xxx,0)求和方法(返回值,起始累加值)
return state.cartList.reduce((sum, items) => sum + items.goods_num, 0)
},
// 选中的商品项
selCartList (state) {
return state.cartList.filter(items => items.isChecked)
},
// 在getters中找getters
// 选中的总数
selCount (state, getters) {
return getters.selCartList.reduce((sum, items) => sum + items.goods_num, 0)
},
// 选中的总价
// toFixed(2)保留两位小数
selPrice (state, getters) {
return getters.selCartList.reduce((sum, items) => {
return sum + items.goods_num * items.goods.goods_price_min
}, 0).toFixed(2)
},
// 是否全选
isAllChecked (state) {
return state.cartList.every(items => items.isChecked)
}
}
而这些数据怎么使用呢?
——用mapGetters就可以在页面渲染了
// 在cart.vue的computed计算属性中
...mapGetters('cart', ['cartTotal', 'selCartList', 'selCount', 'selPrice'])
页面渲染(省略)
这里还有一个小优化,就是在你没有选择任何商品结算时,结算键灰色(下面css有对应的设置)
<div v-if="true" class="goPay" :class="{ disabled: selCount === 0}">结算({{ selCount }})</div>
<div v-else class="delete" :class="{ disabled: selCount === 0}">删除</div>
5. 全选反选功能(小选+全选)
小选可以控制全选
- 给小选框加click点击事件
toggleCheck,在点击事件的时候传入id - 在下面methods写出对应方法,把这个提交过去
toggleCheck - 在store/module/cart.js中提供一个mutation
toggleCheck
<van-checkbox @click="toggleCheck(item.goods_id)" ...></van-checkbox>
toggleCheck (goodsId) {
this.$store.commit('cart/toggleCheck', goodsId)
},
mutations: {
toggleCheck (state, goodsId) {
const goods = state.cartList.find(item => item.goods_id === goodsId)
goods.isChecked = !goods.isChecked
},
}
- 这时再提供一个getters来决定是否全选
isAllChecked- 记得提供了getters后,页面上记得再map映射里加上这个getters
- 在页面内的全选框处,记得加上
:value="isAllChecked"
getters: {
isAllChecked (state) {
return state.cartList.every(item => item.isChecked)
}
}
...mapGetters('cart', ['isAllChecked']),
<div class="all-check">
<van-checkbox :value="isAllChecked" icon-size="18"></van-checkbox>
全选
</div>
全选可以控制小选
- 给全选框注册点击事件
- 然后在下面提供方法
- 在cart.js中提供对应的mutation
<div @click="toggleAllCheck" class="all-check">
<van-checkbox :value="isAllChecked" icon-size="18"></van-checkbox>
全选
</div>
toggleAllCheck () {
this.$store.commit('cart/toggleAllCheck', !this.isAllChecked)
},
mutations: {
toggleAllCheck (state, flag) {
state.cartList.forEach(item => {
item.isChecked = flag
})
},
}
6. 购物车数字框修改数量
- 需要提供对应的mutation
- 加减的数字还要同步到后台(不仅仅是本地)
- 所以需要阅读文档,封装一个“购物车商品更新”的接口
changeCount
- 封装 api 接口 (点击或者输入的时候,需要调接口)
// 更新购物车商品数量
export const changeCount = (goodsId, goodsNum, goodsSkuId) => {
return request.post('/cart/update', {
goodsId,
goodsNum,
goodsSkuId
})
}
- 页面中注册点击事件,传递数据
无论是点击还是输入,都会触发我们写的CountBox
所以如果我们需要监听当前的修改,就只需要countbox监听input事件就可以了
<!-- 既希望保留原本的形参,又需要通过调用函数传参 => 箭头函数包装一层 -->
<!-- value就是我们想要的goods_id -->
<CountBox :value="items.goods_num" @input="value => changeCount(value, items.goods_id, items.goods_sku_id)"></CountBox>
changeCount (goodsNum, goodsId, goodsSkuId) {
// console.log(goodsNum, goodsId, goodsSkuId)
// 调用 vuex 的 action,进行数量的修改,把三个参数都传过去
this.$store.dispatch('cart/changeCountAction', {
goodsNum,
goodsId,
goodsSkuId
})
},
- 提供 action 发送请求, commit mutation
mutations: {
changeCount (state, { goodsId, goodsNum }) {
// console.log(goodsNum, goodsId, goodsSkuId)
// 调用 vuex 的 action,进行数量的修改,把三个参数都传过去
const goods = state.cartList.find(items => items.goods_id === goodsId)
goods.goods_num = goodsNum
}
},
actions: {
async changeCountAction (context, obj) {
// 先本地修改
const { goodsId, goodsNum, goodsSkuId } = obj
context.commit('changeCount', {
goodsId,
goodsNum
})
// 再同步到后台
await changeCount(goodsId, goodsNum, goodsSkuId)
}
}
7. 编辑切换状态
- data 提供数据, 定义是否在编辑删除的状态
data () {
return {
// 编辑状态
isEdit: false
}
},
- 注册点击事件,修改状态(取反)
<span class="edit" @click="isEdit = !isEdit">
<van-icon name="edit" />
编辑
</span>
- 底下按钮根据状态变化
是编辑状态就是删除,不是编辑状态就是结算
<div v-if="!isEdit" :class="{ disabled: selCount === 0 }" class="goPay">
去结算({{ selCount }})
</div>
<div v-else :class="{ disabled: selCount === 0 }" class="delete">删除</div>
- 监视编辑状态,动态控制复选框状态
商城心机:当你点了编辑之后,应该尽可能的少选;跟结算时尽可能全选一样
//!!!!!!!在methods外写,跟methods是平行的
watch: {
isEdit (value) {
// if说明切换到了编辑状态
if (value) {
this.$store.commit('cart/toggleAllCheck', false)
} else {
this.$store.commit('cart/toggleAllCheck', true)
}
}
}
8. 删除功能(也需要走接口)
- 查看接口,封装 api,“删除购物车商品”
( 注意:此处 id 为获取回来的购物车数据的 id ,不是goodsid也不是skuid)
// 删除购物车
export const delSelect = (cartIds) => {
return request.post('/cart/clear', {
cartIds
})
}
- 注册删除点击事件,页面中调用接口
<div v-else :class="{ disabled: selCount === 0 }" @click="handleDel" class="delete">
删除({{ selCount }})
</div>
// 这有个小细节,就是你删完以后可以再自动变成结算的样子(await)
async handleDel () {
// 如果当前没有选中的项,是不能提交的
if (this.selCount === 0) return
await this.$store.dispatch('cart/delSelect')
this.isEdit = false
},
- 提供 actions
actions: {
// 删除购物车数据
async delSelect (context) {
const selCartList = context.getters.selCartList
const cartIds = selCartList.map(items => items.id)
await delSelect(cartIds)
Toast('删除成功')
// 重新拉取最新的购物车数据 (重新渲染)
context.dispatch('getCartAction')
}
},
9. 空购物车处理
- 外面包个大盒子,添加 v-if 判断(包在购物车的开头、列表、底部之外)
<div class="cart-box" v-if="isLogin && cartList.length > 0">
<!-- 购物车开头 -->
<div class="cart-title">
...
</div>
<!-- 购物车列表 -->
<div class="cart-list">
...
</div>
<div class="footer-fixed">
...
</div>
</div>
<div class="empty-cart" v-else>
<img src="@/assets/empty.png" alt="">
<div class="tips">
您的购物车是空的, 快去逛逛吧
</div>
<div class="btn" @click="$router.push('/')">去逛逛</div>
</div>
// 在computed中
isLogin () {
return this.$store.getters.token
}
- 相关样式
.empty-cart {
padding: 80px 30px;
img {
width: 140px;
height: 92px;
display: block;
margin: 0 auto;
}
.tips {
text-align: center;
color: #666;
margin: 30px;
}
.btn {
width: 110px;
height: 32px;
line-height: 32px;
text-align: center;
background-color: #fa2c20;
border-radius: 16px;
color: #fff;
display: block;
margin: 0 auto;
}
}
订单结算台
说明:所有的结算,本质上就是 跳转到“订单结算台”,并且,跳转的同时,需要携带上对应的订单相关参数,具体需要哪些参数,基于“订单结算台”的需求来定
- 静态结构

<div class="pay">
<van-nav-bar fixed title="订单结算台" left-arrow @click-left="$router.go(-1)" />

1. 获取收获地址列表
1 阅读接口文档“收货地址列表”,封装获取地址的接口
import request from '@/utils/request'
// 获取地址列表
export const getAddressList = () => {
return request.get('/address/list')
}
2 页面中 - 调用获取地址
import { getAddressList } from '@/api/address'
data () {
return {
addressList: []
}
},
async created () {
this.getAddressList()
},
computed: {
selectAddress () {
// 这里地址管理不是主线业务,直接获取默认第一条地址
return this.addressList[0] || {}
}
},
methods: {
async getAddressList () {
const { data: { list } } = await getAddressList()
this.addressList = list
}
}
3 页面中 - 进行渲染
根据有res打印得到的这个,可以进行渲染
<!-- 这个详细地址本质上就是拼接 -->
computed: {
longAddress () {
const region = this.selectAddress.region
return region.province + region.city + region.region + this.selectAddress.detail
}
},
<div class="info" v-if="selectAddress?.address_id">
<div class="info-content">
<span class="name">{{ selectAddress.name }}</span>
<span class="mobile">{{ selectAddress.phone }}</span>
</div>
<div class="info-address">
<!-- 这个详细地址本质上就是拼接 -->
{{ longAddress }}
</div>
</div>
2.订单结算 - 封装通用接口(两种情况共用一个接口)
思路分析: 这里的订单结算,有两种情况:
-
购物车结算,需要两个参数
① mode="cart"
② cartIds="cartId"
-
立即购买结算(商品详情),需要三个参数
① mode="buyNow"
② goodsId="商品id"
③ goodsSkuId="商品skuId"
都需要跳转时将参数传递过来
接口文档“订单结算”,封装通用 API 接口 api/order
import request from '@/utils/request'
export const checkOrder = (mode, obj) => {
return request.get('/checkout/order', {
// query参数在get请求里传递,用params
params: {
mode,
delivery: 0,
couponId: 0,
isUsePoints: 0,
...obj // 将我们传过来的参数对象,动态展开
}
})
}
3. 订单结算 -(1)购物车结算
1 跳转时,传递查询参数
layout/cart.vue
<div @click="goPay">结算({{ selCount }})</div>
goPay () {
// 判断有没有选中商品
if (this.selCount > 0) {
// 有选中的 商品 才进行结算跳转
this.$router.push({
path: '/pay',
query: {
mode: 'cart',
cartIds: this.selCartList.map(items => items.id).join(',') // 'cartId,cartId,cartId'
}
})
}
}
2 (pay/index.js)页面中$route.query.接收参数, 调用接口,获取数据
import { checkOrder } from '@/api/order'
data () {
return {
order: {},
personal: {}
}
},
computed: {
mode () {
return this.$route.query.mode
},
cartIds () {
return this.$route.query.cartIds
}
}
async created () {
this.getOrderList()
},
async getOrderList () {
if (this.mode === 'cart') {
const { data: { order, personal } } = await checkOrder(this.mode, { cartIds: this.cartIds })
this.order = order
this.personal = personal
}
}
3 基于数据进行渲染 (item换成items记得)
<!-- 订单明细 -->
<div class="pay-list" v-if="order.goodsList">
<div class="list">
<div class="goods-item" v-for="item in order.goodsList" :key="item.goods_id">
<div class="left">
<img :src="item.goods_image" alt="" />
</div>
<div class="right">
<p class="tit text-ellipsis-2">
{{ item.goods_name }}
</p>
<p class="info">
<span class="count">x{{ item.total_num }}</span>
<span class="price">¥{{ item.total_pay_price }}</span>
</p>
</div>

4. 订单结算 - (2)商品详情立即购买结算
1 点击跳转传参
prodetail/index.vue
<div class="btn" v-if="mode === 'buyNow'" @click="goBuyNow">立刻购买</div>
goBuyNow () {
this.$router.push({
path: '/pay',
query: {
mode: 'buyNow',
goodsId: this.goodsId,
goodsSkuId: this.detail.skuList[0].goods_sku_id,
goodsNum: this.addCount
}
})
}
2 pay/index.js计算属性处理参数
computed: {
...
goodsId () {
return this.$route.query.goodsId
},
goodsSkuId () {
return this.$route.query.goodsSkuId
},
goodsNum () {
return this.$route.query.goodsNum
}
}
3 pay/index.js基于请求时携带参数发请求渲染
async getOrderList () {
...
if (this.mode === 'buyNow') {
const { data: { order, personal } } = await checkOrder(this.mode, {
goodsId: this.goodsId,
goodsSkuId: this.goodsSkuId,
goodsNum: this.goodsNum
})
this.order = order
this.personal = personal
}
}
5. mixins 复用(混用) - 处理登录确认框的弹出
但是你此时的goBuyNow未作任何未登录的处理:需要弹出一个确认框,只有登录才能继续
其实我们上面刚写过提醒登录的弹窗,我们完全可以直接把它cv下来,但是,如果每个需要这个的我们都cv,那么代码的工程量就太大了,所以最好的方式,就是把这一段封装起来
法1:在组件内封装一个方法,然后在需要的地方调用
法2:把它封装到一个公共位置,那就不止现在这个组件可以用了
1 在src下新建一个 mixin 文件 mixins/loginConfirm.js
export default {
// 此处编写的就是 Vue组件实例的 配置项,通过一定语法,可以直接混入到组件内部
// 这里面可以写比如:data methods computed 生命周期函数 ...
// 注意点:
// 1. 如果此处 和 组件内,提供了同名的 data 或 methods, 则组件内优先级更高
// 2. 如果编写了生命周期函数,则mixins中的生命周期函数 和 页面的生命周期函数,
// 会用数组管理,统一执行(这个不会冲突)
methods: {
// 是否需要弹登录确认框
// (1) 需要,返回 true,并直接弹出登录确认框
// (2) 不需要,返回 false
loginConfirm () {
if (!this.$store.getters.token) {
this.$dialog.confirm({
title: '温馨提示',
message: '此时需要先登录才能继续操作哦',
confirmButtonText: '去登陆',
cancelButtonText: '再逛逛'
})
.then(() => {
// 如果希望,跳转到登录 => 登录后能回跳回来,需要在跳转去携带参数 (当前的路径地址)
// this.$route.fullPath (会包含查询参数)
this.$router.replace({
path: '/login',
query: {
backUrl: this.$route.fullPath
}
})
})
.catch(() => {})
return true
}
return false
}
}
}
2 在你需要的页面中导入(比如 pay/index.vue),混入方法
import loginConfirm from '@/mixins/loginConfirm'
export default {
name: 'ProDetail',
mixins: [loginConfirm],// 写数组的目的是,你以后还可以写多个,直接在里面加就可以
...
}
3 页面中调用 混入的方法
async addCart () {
if (this.loginConfirm()) {
return
}
const { data } = await addCart(this.goodsId, this.addCount, this.detail.skuList[0].goods_sku_id)
this.cartTotal = data.cartTotal
this.$toast('加入购物车成功')
this.showPannel = false
console.log(this.cartTotal)
},
goBuyNow () {
if (this.loginConfirm()) {
return
}
this.$router.push({
path: '/pay',
query: {
mode: 'buyNow',
goodsId: this.goodsId,
goodsSkuId: this.detail.skuList[0].goods_sku_id,
goodsNum: this.addCount
}
})
}
主要就是这段调用:
if (this.loginConfirm()) {
return
}
提交订单并支付
1 封装 api 通用方法(统一余额支付)order.js
// 提交订单
export const submitOrder = (mode, params) => {
return request.post('/checkout/submit', {
mode,
delivery: 10, // 物流方式 配送方式 (10快递配送 20门店自提)
couponId: 0, // 优惠券 id
payType: 10, // 余额支付
isUsePoints: 0, // 是否使用积分
...params
})
}
- pay/index.js买家留言绑定
data () {
return {
remark: ''// 备注留言
}
},
<div class="buytips">
<textarea v-model="remark" placeholder="选填:买家留言(50字内)" name="" id="" cols="30" rows="10">
</textarea>
</div>
3 注册点击事件,提交订单并支付
<div class="tipsbtn" @click="submitOrder">提交订单</div>
// 提交订单
async submitOrder () {
if (this.mode === 'cart') {
await submitOrder(this.mode, {
remark: this.remark,
cartIds: this.cartIds
})
}
if (this.mode === 'buyNow') {
await submitOrder(this.mode, {
remark: this.remark,
goodsId: this.goodsId,
goodsSkuId: this.goodsSkuId,
goodsNum: this.goodsNum
})
}
this.$toast.success('支付成功')
this.$router.replace('/myorder')
}

点击 tab 切换渲染
1 封装获取订单列表的 api 接口“我的-订单”
api/order.js
// 订单列表
export const getMyOrderList = (dataType, page) => {
return request.get('/order/list', {
params: {
dataType,
page
}
})
}
2 给 tab 绑定 name 属性
<van-tabs v-model="active" sticky>
<van-tab name="all" title="全部"></van-tab>
<van-tab name="payment" title="待支付"></van-tab>
<van-tab name="delivery" title="待发货"></van-tab>

</van-tabs>
data () {
return {
active: this.$route.query.dataType || 'all',
page: 1,
list: []
}
},
3 封装调用接口获取数据
import { getMyOrderList } from '@/api/order'
methods: {
async getOrderList () {
const { data: { list } } = await getMyOrderList(this.active, this.page)
list.data.forEach((items) => {
items.total_num = 0
items.goods.forEach(goods => {
items.total_num += goods.total_num
})
})
this.list = list.data
}
},
watch: {

退出登录功能
1 注册点击事件
<button @click="logout">退出登录</button>
2 提供方法
//user.vue
methods: {
logout () {
this.$dialog.confirm({
title: '温馨提示',
message: '你确认要退出么?'
})
.then(() => {
// 退出是一个动作 => 包含了两步,分别是将 user 和 cart 进行重置
// 所以我们再写一个actions
this.$store.dispatch('user/logout')
})
.catch(() => {
})
}
}
// store/module/user.js
actions: {
logout (context) {
// 个人信息要重置
context.commit('setUserInfo', {})
// 购物车信息要重置(需要跨模块去调用我们的mutation)
// { root: true }开启全局模式,不写的话调的就是在当前模块中找
context.commit('cart/setCartList', [], { root: true })
}
},
项目打包优化
(1) 打包命令
vue脚手架工具已经提供了打包命令,直接使用即可。
yarn build 或 npm run build
在项目的根目录会自动创建一个文件夹dist,dist中的文件就是打包后的文件,只需要放到服务器中即可。
(2) 配置publicPath
在 vue.config.js 文件里写
module.exports = {
// 设置获取.js,.css文件时,是以相对地址为基准的。
// https://cli.vuejs.org/zh/config/#publicpath
publicPath: './'
}
写完之后再重新打包,文件内容会替换
(3) 路由懒加载
路由懒加载 & 异步组件, 不会一上来就将所有的组件都加载,而是访问到对应的路由了,才加载解析这个路由对应的所有组件
官网链接:router.vuejs.org/zh/guide/ad…
当打包构建应用时,JavaScript 包会变得非常大,影响页面加载。如果我们能把不同路由对应的组件分割成不同的代码块,然后当路由被访问的时候才加载对应组件,这样就更加高效了。
- 异步组件改造
const ProDetail = () => import('@/views/prodetail')
const Pay = () => import('@/views/pay')
const MyOrder = () => import('@/views/myorder')
- 路由中应用
const router =new VueRouter({
routes:[
...
{path:'/prodetail/:id',component:ProDetail}
{path:'/pay',component:Pay}
...
]
})
