低代码可视化-uniapp购物车页面-代码生成器
购物车页面是电子商务网站或应用程序中的一个关键功能页面，它允许用户查看、编辑和管理他们选择加入购物车的商品。下面通过低代码可视化实现一个uniapp购物车页面，把购物车整个事件都集成进去。实现完成后可以保存为页面模板。
收货地址选择
如果尚未选择收货地址，用户可以在此选择或输入新收货地址。
API加载收货地址
api加载当前用户所有收货地址，如果没有收货地址，提示先新增地址。
如果有地址，支持显示用户收货地址。
商品列表
循环显示用户购物车的数据。
商品图片：显示商品的缩略图，帮助用户快速识别。
商品名称：商品的完整名称或描述。
价格：每个商品的单价，以及可能的折扣价或原价对比。
数量选择器：允许用户增加或减少所选商品的数量。
总价计算
商品总价：所有商品单价乘以数量的总和。。
订单总价：商品总价加上税运费（如果有）的最终金额。
