前言

完整版演示

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

1. Tabs 标签页 和 Card 完成右侧的商品选择
2. el-autocomplete 完成会员的检索
3. 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
