摘自Syntaxerror：“意外令牌”） |如果在JavaScript中使用其他语句
如果其他条件有语法错误，看来我可以帮忙吗？控制台吐出此链接{/home/ccuser/workspace/javascript_101_unit_3_v2/rockpaperscissors.js:38 }）; }和错误指向“）”
userInput = userInput.toLowerCase();
if (userInput !== "rock" && userInput !== "paper" && userInput !== "scissor") {
console.log("Error");
} else {
return userInput;
}
}
const getComputerChoice = () => {
const randomNumber = Math.floor(Math.random() * 3);
switch(randomNumber){
case 0: return "scissor";
break;
case 1: return "rock";
break;
default: return "paper";
break;
}
}
const determinWinner = (userChoice, computerChoice) => {
if(userChoice === computerChoice){
return "Its a tie";
} else if (userChoice === "rock" && computerChoice ==="scissor"){
return "The user won";
} else if (userChoice === "paper" && computerChoice ==="rock"){
return "The user won";
} else if (userChoice === "scissor" && computerChoice ==="paper"){
return "The user won";
} else if (userChoice === "rock" && computerChoice ==="paper"){
return "The computer won";
} else if (userChoice === "paper" && computerChoice ==="scissor"){
return "The computer won";
} else if (userChoice === "scissor" && computerChoice ==="rock"){
return "The computer won";
}
It seems my if else condition has a syntax error, can somebody help? The console spits out this link { /home/ccuser/workspace/javascript_101_Unit_3_v2/rockPaperScissors.js:38
}); } and an error points to the ")"
userInput = userInput.toLowerCase();
if (userInput !== "rock" && userInput !== "paper" && userInput !== "scissor") {
console.log("Error");
} else {
return userInput;
}
}
const getComputerChoice = () => {
const randomNumber = Math.floor(Math.random() * 3);
switch(randomNumber){
case 0: return "scissor";
break;
case 1: return "rock";
break;
default: return "paper";
break;
}
}
const determinWinner = (userChoice, computerChoice) => {
if(userChoice === computerChoice){
return "Its a tie";
} else if (userChoice === "rock" && computerChoice ==="scissor"){
return "The user won";
} else if (userChoice === "paper" && computerChoice ==="rock"){
return "The user won";
} else if (userChoice === "scissor" && computerChoice ==="paper"){
return "The user won";
} else if (userChoice === "rock" && computerChoice ==="paper"){
return "The computer won";
} else if (userChoice === "paper" && computerChoice ==="scissor"){
return "The computer won";
} else if (userChoice === "scissor" && computerChoice ==="rock"){
return "The computer won";
}

您定义一个外壳，但是您缺少最终
}You defining an enclosure, but you're missing the final
}您只是错过了
destryinwinner（...）方法的最后/关闭}。这就是您的代码外观！
You are just missing the last/closing
}for yourdeterminWinner(...)method.This is how you code should look like!
尝试以下操作：
在
ComputerChoice的末尾）{，添加：，看看是否有效！Try this:
At the end of
computerChoice){, add:and see if that works!
