Question

我正在尝试使用产品的复选框（绑定到该复选框的产品价格）并从另一个输入中选择的数字中获取总价格，来计算商品的总价。但这不能按预期方式工作，因为当我单击第二个产品时，它的价格自动计算出来，而无需我选择所需的项目数。如何解决此问题，以便仅在提供数量时才计算总价？这是我的代码：

create table #sprocResult (
  -- define columns that match the results of the sproc.
  -- You should also define a PK, and possibly other indexes
)

insert into #sprocResult exec proc1

HTML

 const vm = new Vue ({
        el: "#app",
        data: {
            checkedValue: [],
            amount: [],
            items: [{name:"amazing", price:"2000"},
            {name:"kulahappy", price:"1000"},
            {name:"Yolo", price:"3000"}]
        },
        computed: {
            totalPrice (){
                const total = this.checkedvalue.reduce((acc, curr) => acc + parseInt(curr, 10), 0)
                const number = this.amount.reduce((acc, curr) => acc + parseInt(curr, 10), 0)
          const sum = total * number
          return sum
            }
        }
    })

从动态输入值中求和
