当我的代码运行时，您可以看到当用户输入房间数量，选择签入并签出日期并点击提交时，会出现一个表格，其中包含房间名称，为所选房间输入的数量和价格根据房间数量。此外，还会显示另一个表格，其中包括从登记入住到退房的天数以及总数。总计被假设为天数乘以价格。
出现的第一个表是使用以下javascript中显示的outputArray（）函数创建的。第二个表是使用CalcTotals（）函数创建的。我需要找到一种方法来将选定的天数乘以价格并将其作为总和输出。有没有办法将这两个东西结合起来，因为它们是在不同的函数中计算的？

答案 0 :(得分：0)
您可以在outputArray中计算房间的价格，类型和数量。只需在CalcTotals而不是outputArray结束时拨打QtyVal即可向outputArray提供所需的信息作为参数。如果您想在相同的时间内预订每个房间，您可以在必要时为所有三种类型的房间添加type * price * number，并让CalcTotals计算天数并将其乘以给定的总和作为outputArray的论据。
我希望没有解释得那么糟糕？
