前言
前面我们对会员系统 分类和商品的开发 完成了收银所需的基础信息 下面我们开始完成收银台的开发
简单画了一个收银的流程图大家参考下
从这张图我们可以分析一下几点
- 可以选择会员或散客收银
- 选择会员使用相应的会员价结算
- 使用会员卡则在价格基础根据卡折扣结算
根据上述分析我搭建了一个简单的收银台
- 左边显示会员和已选择的商品信息
- 右边显示商品的价格信息
- 商品选择后可以修改数字
- 总金额自动计算
- 后续完成挂单功能便于保证收银连续性
开发中运用的组件
- Tabs 标签页 和 Card 完成右侧的商品选择
- el-autocomplete 完成会员的检索
- InputNumber Table 完成购物车开发
收银台运用过多组件会导致页面很乱 我们后续需要进行组件的封装
