Question

所以我被要求重建一个网站，但是我想弄清楚下面的javascript究竟做了什么，从我在网上发现它的写得非常糟糕，可能为什么我无法弄明白

主要是'SPCost + =（nBks

完整表格的网站为http://dynamic-stationery.com/online_order_form/

var setup = 110;  // film and screen
var perBk = 0.77;  // printing cost per book
var thresh = 200;
var minCost = 20;
var GST = 0.1;
var numCostPBk = nums ? 1.0 : 0.0;

var SPCost;
if (CC) {
  SPCost = nInks * (setup + nBks * (perBk + numCostPBk));
  SPCost += nBks < thresh ? minCost : nBks * minCost / thresh;
  SPCost *= 1 + GST;
  SPCost = Round(SPCost);
} else {
  SPCost = 0;
}

Answer 1

可以读出类似这样的内容

SPCost = Number of Inks * Setup Fee (110) + Number of Books * (perBk (0.77) +  numCostPBk (If numbers, 1.0 else 0.0)) 
The above will return a single number. 

SPCost += IF number of books is less than thresh (200) then minCost else Number of books * minCost (20) / thresh (200) 
SPCost += 1+ GST (0.1)

^^ Add these numbers to the first one

SPCost = round the combined totals.

javascript帮助，无法解码
