修复多门店收银台分单退款问题

问题描述：

分单时退款金额和退款商品数量的变化

解决方法：

手动修改

• 文件路径 src/pages/order/index.vue
• 在 template 中修改这段代码

• 在 computed 中增加 productSelection

 computed: {
    refundProductNum() {
      return this.refundProduct.reduce((total, { refundNum }) => (total + refundNum), 0);
    },
    // 退款商品选择
    productSelection() {
      // 使用Map优化性能
      const productMap = new Map(this.refundProduct.map(item => [item.id, item]));
      return this.refundSelection.filter(item => productMap.has(item.id)).map(item => productMap.get(item.id));
    }
  }

• 在 methods 中修改 submitRefund、selectionChange，增加 numChange、refundMoneyCompute

    submitRefund() {
      let data = {
        refund_price: this.refundMoney,
        is_split_order: this.isSplitOrder,
      };
      if (this.isSplitOrder) {
        if (!this.refundSelection.length) {
          return this.$Message.warning('请选择需要退款的商品');
        }
        // 组装退款商品
        data.cart_ids = this.productSelection.map(({ id, refundNum }) => {
          return { cart_id: id, cart_num: refundNum };
        });
      }
      openRefund(this.selectOrderData.id, data).then(res => {
        this.$Message.success(res.msg);
        this.refundModal = false;
        this.reloading = true;
        this.limitTemp = this.orderData.limit;
        this.pageTemp = this.orderData.page;
        this.orderData.limit *= this.orderData.page;
        this.orderData.page = 1;
        this.getOrderList();
      }).catch(res => {
        this.$Message.error(res.msg);
      });
    },
    // 选择商品
    selectionChange(selection) {
      this.refundSelection = selection;
      this.refundMoneyCompute();
    },
    // 改变商品数量
    numChange() {
      this.refundMoneyCompute();
    },
    // 计算退款金额
    refundMoneyCompute() {
      let refundMoney = 0;
      for (const item of this.productSelection) {
        try {
          // 使用trycatch处理计算退款金额可能发生的错误
          refundMoney = this.$computes.Add(refundMoney, this.$computes.Mul(item.refundNum, item.refundPrice));
        } catch (error) {
          console.error('计算退款金额发生错误', error);
          break;
        }
      }
      this.refundMoney = refundMoney;
    }
