卡在石头剪刀布上

Question

我是编码新手，我必须做这个剪刀石头布，但找不到我的错误，它仍然每次都显示其他结果。 欢迎任何帮助

// Get the computer choice
function getComputerChoice() {
    "use strict";
    const computerPlay = Math.floor(Math.random()*3);
    if (computerPlay === 1){
        return("rock")
    }
    else if(computerPlay === 2){
        return ("paper")
    }
    else {
        return ("scissors")
    }
}

// Get the user choice
function getUserChoice(){
    prompt("Please enter 'rock', 'paper', 'scissors': ").toLowerCase();
}

// Play a round
function playRound(){
    let computerSelection = getComputerChoice();
    let playerSelection = getUserChoice();
    if (computerSelection === playerSelection){
        console.log("Game is a Tie")
    }  
    else if (computerSelection == 'paper' && playerSelection == 'rock'){
        console.log("Computer Win")
    }
    else if (computerSelection == 'rock' && playerSelection == 'scissors'){
        console.log("Computer Win")
    }
    else if (computerSelection == 'scissors' && playerSelection == 'paper'){
        console.log("Computer Win")
    }
    else {
        console.log("User Win")
    }   
}

// Play Game function
function playGame(){
    for (let i = 0; i < 5; i++){
        playRound()
    }
}

playGame()

我尝试如果它似乎错过了正确运行的东西。

解决方案

您错过了 getUserChoice 方法中的 return 关键字。

function getUserChoice(){
    return prompt("Please enter 'rock', 'paper', 'scissors': ").toLowerCase();
}
