地址切换交互实现—打开弹窗

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.valueshowDialog.value = falseactiveAddress.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

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.idrouter.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>
