我在理解 JavaScript 時遇到問題。我有以下任務。我正在嘗試增加最終成本。額外的奶酪。
var extraCheeseUpcharge = 1.5
var extraCheese = confirm("Would you like extra cheese?")
if (extraCheese == true) {
pizza.extraCheese = true;
extraCheese = extraCheeseUpcharge pizza.cost;
} else {
pizza.extraCheese = false;
extraCheese = extraCheeseUpcharge - pizza.cost;
}
uj5u.com熱心網友回復：
var extraCheeseUpcharge = 1.5
var extraCheese = confirm("Would you like extra cheese?")
if (extraCheese == true) {
pizza.extraCheese = true;
extraCheese = extraCheeseUpcharge pizza.cost;
} else {
pizza.extraCheese = false;
extraCheese = pizza.cost;
}
如果 extraCheese 為假，這里的最終價格將等于 Pizza.cost 而不是 extraCheeseUpcharge - Pizza.cost
