需要幫助解決循環問題

Question

我最近開始學習Javascript，很享受它。所以，在瞭解了關於循環的一些信息後，我決定改進一個簡單的Rock，Scissors，Paper遊戲。改進是讓玩家獲勝和計算機勝利值作爲變量，而不是循環函數，直到playerScore變量達到10的值。儘管我試圖獲得一般邏輯和我犯了一個錯誤，但語法還不是很好。 。

爲了達到我的目標，我已經聲明瞭兩個變量 - playerScore和computerScore，其初始值爲0。每個玩家贏或電腦贏了，我決定增加+ 1變量之後。

比開始的比賽中，我聲明瞭一個函數瑣事（），並使用循環雖然它。循環似乎是無限的，不止於此，當前的結果不會記錄到控制檯。任何幫助非常感謝，將幫助我理解邏輯遠遠超過我通過的任何課程。

下面的代碼：

var playerScore = 0; 
var computerScore = 0; 

function getUserChoice() { 
    var userInput = prompt('Choose stone, scissors or paper'); 
    userInput = userInput.toLowerCase(); 
    if(userInput === 'stone' || userInput === 'paper' || userInput === 'scissors' || userInput === 'bomb') { 
    return userInput; 
    } 
    else { 

    alert('Error! Choose stone, scissors or paper!'); 

    } 
} 

function getComputerChoice() { 
var randomNumber = Math.floor(Math.random() *3); 
    if(randomNumber === 1) { 
    return 'stone'; 
    } 

    else if(randomNumber === 2) { 
    return 'paper'; 
    } 

    else { 
    return 'scissors'; 

    } 
} 


function determineWinner (userChoice, computerChoice) { 
    if(userChoice === computerChoice) { 
    return 'That's a tie!'; 
    } 

    if(userChoice === 'stone') { 
    if(computerChoice === 'scissors') { 

     playerScore = playerScore + 1; 
     сonsole.log(playerScore); 
     console.log(computerScore); 
     return 'Player won!'; 


    } 
    else { 
     if(computerChoice === 'paper') { 

     computerScore = computerScore + 1; 
     сonsole.log(playerScore); 
     console.log(computerScore); 

     return 'Computer won!' 

     } 
    } 
    } 

    if(userChoice === 'paper') { 
    if(computerChoice === 'scissors') { 
     computerScore = computerScore + 1; 
     сonsole.log(playerScore); 
     console.log(computerScore); 
     return 'Computer won!'; 
    } 
    else { 
     if(computerChoice === 'stone') { 
     playerScore = playerScore + 1; 
     сonsole.log(playerScore); 
     console.log(computerScore); 
     return 'Player wonи!'; 
    } 
    } 
     } 
    if(userChoice === 'scissors') { 
    if(computerChoice === 'stone') { 
     computerScore = computerScore + 1; 
     сonsole.log(playerScore); 
     console.log(computerScore);  
     return 'Computer won!'; 
    } 
    else { 
     if(computerChoice === 'paper') { 
     playerScore = playerScore + 1; 
     сonsole.log(playerScore); 
     console.log(computerScore); 
     return 'Player won!'; 
     } 
    } 
     } 

     if(userChoice === 'bomb') { 
     if(computerChoice === 'stone' || computerChoice === 'scissors' || computerChoice === 'paper') { 
    playerScore = playerScore + 1; 
     сonsole.log(playerScore); 
     console.log(computerScore); 
     return 'Player won!'; 
      return 'Player won!'; 

     } 
     } 

    } 


while(playerScore < 10) { 
function playGame() { 
    var userChoice = getUserChoice(); 
    var computerChoice = getComputerChoice(); 
    alert('Player chose' + ' ' + userChoice + '!'); 
alert('Computer chose' + ' ' + computerChoice + '!'); 

alert(determineWinner(userChoice, computerChoice)); 
playGame() = false; 
} 
}; 



playGame(); 

Answer 1

您需要在while循環進入功能playGame()。

function playGame() { 
    while(playerScore < 10) { 
    var userChoice = getUserChoice(); 
    var computerChoice = getComputerChoice(); 
    alert('Player chose' + ' ' + userChoice + '!'); 
    alert('Computer chose' + ' ' + computerChoice + '!'); 

    alert(determineWinner(userChoice, computerChoice)); 
    } 
}
