黑马程序员前端 Vue3 小兔鲜电商项目——（十）订单页

路由配置和基础数据渲染

模板代码

新建 src\views\Checkout\index.vue 文件，添加以下代码：

<script setup>
const checkInfo = {}  // 订单对象
const curAddress = {}  // 地址对象

</script>

<template>
  <div class="xtx-pay-checkout-page">
    <div class="container">

</style>

配置路由

src\router\index.js 中对路由进行配置：

routes: [
  {
    
    
    path: '/',
    component: Layout,
    children: [
      ...
      {
    
    
        path: "checkout",
        component: Checkout
      }
    ]
  }
]

封装接口

新建 src\apis\checkout.js 文件，添加获取订单详情的接口：

import http from '@/utils/request'

// 获取详情接口
export const getCheckInfoAPI = () => {
    
    
    return http({
    
    
        url: '/member/order/pre'
    })
}

渲染数据

src\views\Checkout\index.vue 文件中调用接口获取订单数据，遍历地址：

<script setup>
import {
    
     getCheckInfoAPI } from '@/apis/checkout';
import {
    
     ref, onMounted } from 'vue'

const checkInfo = ref({
    
    })  // 订单对象
const curAddress = ref({
    
    })  // 地址对象

const getCheckInfo = async () => {
    
    
    const res = await getCheckInfoAPI()
    checkInfo.value = res.result
    //适配默认地址
    //从地址列表中筛选出来 isDefault === 0 那一项
    const item = checkInfo.value.userAddresses.find(item => item.isDefault === 0)
    curAddress.value = item
}
onMounted(() => {
    
    
    getCheckInfo()
})

</script>

切换地址-打开弹框交互

src\views\Checkout\index.vue 底部添加弹窗部分的代码：

<!-- 切换地址 -->
<el-dialog title="切换收货地址" width="30%" center>
  <div class="addressWrapper">
    <div class="text item" v-for="item in checkInfo.userAddresses" :key="item.id">
      <ul>
        <li><span>收<i />货<i />人：</span>{
   
   { item.receiver }} </li>
        <li><span>联系方式：</span>{
   
   { item.contact }}</li>
        <li><span>收货地址：</span>{
   
   { item.fullLocation + item.address }}</li>
      </ul>
    </div>
  </div>
  <template #footer>
    <span class="dialog-footer">
      <el-button>取消</el-button>
      <el-button type="primary">确定</el-button>
    </span>
  </template>
</el-dialog>
<!-- 添加地址 -->

定义变量控制弹窗显示：

//控制弹窗打开
const showDialog = ref(false)

弹窗绑定数据：

<el-dialog v-model="showDialog" title="切换收货地址" width="30%" center>
  ...
</el-dialog>

【切换地址】按钮绑定事件：

<div class="action">
  <el-button size="large" @click="showDialog = true">切换地址</el-button>
  <el-button size="large">添加地址</el-button>
</div>

切换地址-地址切换交互

基础思想：记录当前点击项，通过动态class判断当前div是否有激活类名

src\views\Checkout\index.vue 中编写方法记录地址信息：

//切换地址
const activeAddress = ref({
    
    })
const switchAddres  = (item)=>{
    
    
    activeAddress.value=item
}
//覆盖地址
const confirm =()=>{
    
    
    curAddress.value = activeAddress.value
    showDialog.value=false
}

绑定切换地址，激活地址事件：

<!-- 切换地址 -->
<el-dialog v-model="showDialog" title="切换收货地址" width="30%" center>
  <div class="addressWrapper">
    <div class="text item" :class="active:item.id===activeAddress.id" @click="switchAddress(item)" v-for="item in checkInfo.userAddresses" :key="item.id">
      <ul>
        <li><span>收<i />货<i />人：</span>{
   
   { item.receiver }} </li>
        <li><span>联系方式：</span>{
   
   { item.contact }}</li>
        <li><span>收货地址：</span>{
   
   { item.fullLocation + item.address }}</li>
      </ul>
    </div>
  </div>
  <template #footer>
    <span class="dialog-footer">
      <el-button>取消</el-button>
      <el-button type="primary" @click="confirm">确定</el-button>
    </span>
  </template>
</el-dialog>

生成订单

确定结算信息没有问题之后，点击提交订单按钮，需要做以下俩个事情：

1. 调用接口生成订单id,并且携带id跳转到支付页
2. 调用更新购物车列表接口，更新购物车状态

支付页组件

src\views\Pay\index.vue 文件，代码如下：

<script setup>
const payInfo = {}
</script>

<template>
  <div class="xtx-pay-page">
    <div class="container">
      <!-- 付款信息 -->
      <div class="pay-info">
        <span class="icon iconfont icon-queren2"></span>
        <div class="tip">
          <p>订单提交成功！请尽快完成支付。</p>
          <p>支付还剩 <span>24分30秒</span>, 超时后将取消订单</p>
        </div>
        <div class="amount">
          <span>应付总额：</span>
          <span>¥{
   
   { payInfo.payMoney?.toFixed(2) }}</span>
        </div>
      </div>
      <!-- 付款方式 -->
      <div class="pay-type">
        <p class="head">选择以下支付方式付款</p>
        <div class="item">
          <p>支付平台</p>
          <a class="btn wx" href="javascript:;"></a>
          <a class="btn alipay" :href="payUrl"></a>
        </div>
        <div class="item">
          <p>支付方式</p>
          <a class="btn" href="javascript:;">招商银行</a>
          <a class="btn" href="javascript:;">工商银行</a>
          <a class="btn" href="javascript:;">建设银行</a>
          <a class="btn" href="javascript:;">农业银行</a>
          <a class="btn" href="javascript:;">交通银行</a>
        </div>
      </div>
    </div>
  </div>

封装订单接口

src\apis\checkout.js 封装创建订单的接口：

// 创建订单
export const createOrderAPI = (data) => {
    
    
  return http({
    
    
    url: '/member/order',
    method: 'POST',
    data
  })
}

绑定事件

点击【提交订单】按钮，创建订单，购物车清空：

<script setup>
  import { getCheckInfoAPI,createOrderAPI } from '@/apis/checkout'
  import { ref, onMounted } from 'vue'
  import { useRouter } from 'vue-router'
  import { useCartStore } from '@/stores/cartStore'

  const cartStore = useCartStore()
  const router = useRouter()

  // 创建订单
  const createOrder = async () => {
    const res = await createOrderAPI({
      deliveryTimeType: 1,
      payType: 1,
      payChannel: 1,
      buyerMessage: '',
      goods: checkInfo.value.goods.map(item => {
        return {
          skuId: item.skuId,
          count: item.count
        }
      }),
      addressId: curAddress.value.id
    })
    const orderId = res.result.id
    router.push({
      path: '/pay',
      query: {
        id: orderId
      }
    })
  }
