    <div class="total">
          <el-button size="large" type="primary" @click="$router.push('/checkout')">下单结算</el-button>
        </div>

基础数据渲染

在这里插入图片描述
apis/chekout.js

import request from '@/utils/request'
/**
 * 获取结算信息
 */
export const getCheckoutInfoAPI = () => {
  return request({
    url:'/member/order/pre'
  })
}

chekout/index.vue

<script setup>
import { getCheckInfoAPI, createOrderAPI } from '@/apis/checkout'
import { useRouter } from 'vue-router'
import { onMounted, ref } from 'vue'
import { useCartStore } from '@/stores/cartStore'
const cartStore = useCartStore()
const router = useRouter()
// 获取结算信息
const checkInfo = ref({}) // 订单对象
const curAddress = ref({}) // 默认地址
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>

<template>
              <div class="none" v-if="!curAddress">您需要先添加收货地址才可提交订单。</div>
              <ul v-else>
                <li><span>收<i />货<i />人：</span>{{ curAddress.receiver }}</li>
                <li><span>联系方式：</span>{{ curAddress.contact }}</li>
                <li><span>收货地址：</span>{{ curAddress.fullLocation }} {{ curAddress.address }}</li>
              </ul>
            </div>
</template>

地址切换交互实现—打开弹窗

在这里插入图片描述
需求分析
1️⃣打开弹框交互：点击切换地址按钮，打开弹框，回显用户可选地址列表
2️⃣切换地址交互：点击切换地址，点击确定按钮，激活地址替换成默认收货地址
弹框模版

const showDialog = ref(false)
<el-dialog v-model="showDialog" 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>

添加按钮事件

 <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>

地址切换交互实现—激活交互实现

原理
地址切换是我们经常遇到的tab切换类需求，这类需求的实现逻辑都是相似的
1️⃣点击时记录一个当前激活地址对象activeAddress，点击哪个地址就把哪个地址对象记录下来
2️⃣通过动态类名：class控制激活样式类型active是否存在，判断条件为：激活地址对象的id===当前项id

<script setup>
// 切换地址
const activeAddress = ref({})
const switchAddress = (item) => {
  activeAddress.value = item
}
const confirm = () => {
  curAddress.value = activeAddress.value
  showDialog.value = false
  activeAddress.value = {}
}
</script>
<template>
<div class="text item" 
  :class="{ active: activeAddress.id === item.id }" 
  @click="switchAddress(item)"
  :key="item.id">
</div>
</template>
 <!-- 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: activeAddress.id === item.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>

生成订单功能实现

业务需求
确定结算信息没有问题之后，点击提交订单按钮，需要做以下两件事
1️⃣调用接口生成订单id，并且携带id跳转到支付页
2️⃣调用更新购物车列表接口，更新购物车状态
在这里插入图片描述

准备生成订单接口

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

调用接口携带id跳转路由

<script setup>
import { useCartStore } from '@/stores/cartStore'
const cartStore = useCartStore()
import { createOrderAPI } from '@/apis/checkout'
// 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
    }
  })
    // 更新购物车
  cartStore.updateNewList()
}

</script>

<template>
    <!-- 提交订单 -->
    <div class="submit">
      <el-button @click="createOrder" type="primary" size="large">提交订单</el-button>
    </div>
</template>
