Answer 1

这是删除所有错误后的JavaScript：

var drink, ounces, price;
drink = prompt("Enter the drink type: espresso, latte, cappuccino, americano");
ounces = parseInt(prompt("Enter the oz: 8, 12, 16"));
var shots = parseFloat(prompt("Enter the number of shots"));
if (drink === "espresso") price = 1.40;
if ((drink === "latte") || (drink === "cappuccino")) {
  if (ounces === 8) price = 1.95;
  else if (ounces === 12) price = 2.35;
  else if (ounces === 16) price = 2.75;
}
if (drink === "americano") price = 1.20 + ((ounces - 8) / 8) * 0.30;
price = price + shots * 0.50;
price = price * 1.055;
price = Math.round(price * 100) / 100;
alert("Your " + ounces + "oz. " + drink + "with " + shots + "shots of espresso costs: $ " + price);
