石头剪刀布游戏的 JavaScript 错误消息

Question

请我需要以下代码的帮助。我收到此错误消息SyntaxError:预期表达式，获得关键字“if”，我认为我正在做正确的事情。

var userChoice = prompt("Do you choose rock, paper or scissors?");
var computerChoice = Math.random();
`enter code here`
if (computerChoice < 0.34) {
  computerChoice = "rock";
} else if (computerChoice <= 0.67) {
  computerChoice = "paper";
} else {
  computerChoice = "scissors";
}
console.log("Computer: " + computerChoice);
var compare = function(choice1, choice2)
if (choice1 === choice2) {
  return "The result is a tie!";
}

Answer 1

Javascript 中函数的内容放在大括号内。所以你当前的代码

var compare = function(choice1, choice2)
if (choice1 === choice2) {
  return "The result is a tie!";
}

将成为

var compare = function(choice1, choice2)
{
    if (choice1 === choice2) {
      return "The result is a tie!";
    }
}
