Question

我试图计算一个座位的成本取决于选择的数量，问题是第一个座位的成本与其余部分不同。

第一个= 2250 额外座位收费为995

我的语法和计算应该是什么？

//seats variable

var costOfSeats;


//Calculate cost of seats and display cost of seats

$('#range--seats').on("change", function() {

if ($(this).val(1)) {
  costOfSeats == 2250;
} else {
  costOfSeats == costOfSeats + ($(this).val(-1) * 995);// problem here
}

$('.output--seats').val("£" + costOfSeats);
}).trigger("change");

Answer 1

var n = 3; //number of seats
var sum = 0;
var extraSeat = 995;
var seat = 2250;

if (n != 0) {
    sum = seat + ((n-1) * extraSeat)
}

您使用的是if ($(this).val(1)) { costOfSeats == 2250; } else { costOfSeats == costOfSeats + ($(this).val(-1) * 995);// problem here }，而不是costOfSeats == costOfSeats。您正在比较值而不是分配它们
