Question

當用戶和計算機綁定時，它一直告訴我我輸了而不是被綁定。

<html>
<head>        
    <title>Rock, Paper and Scissors</title>        
</head>
<body>
    <p>Rock, Paper and Scissors!</p>        
    <input type="text" id ="textChoice">        
    <button id="submit">Submit</button>        
    <p id="paragraphChoice"></p>

    <script type="text/javascript">            
        document.getElementById("submit").onclick = function() {                
            var computerChoice = ["rock", "paper", "scissors"];            
            var computerGuess = 
                computerChoice[Math.floor(Math.random() * computerChoice.length)];                
            var userGuess = document.getElementById("textChoice").value;

            if (userGuess === computerGuess) {                    
                document.getElementById("paragraphChoice").innerHTML = 
                    "You tied! The computer choose "+ computerGuess; //Both tied!                   
            }

            if (userGuess === "rock") {                    
                if (computerGuess === "scissors") {
                    //rock wins
                    document.getElementById("paragraphChoice").innerHTML =
                        "You won! The computer choose "+ computerGuess;                        
                } else {
                    //paper wins
                    document.getElementById("paragraphChoice").innerHTML =
                        "You lost! The computer choose "+ computerGuess;                        
                }                    
            }

            if (userGuess === "paper") {                    
                if (computerGuess === "rock") {
                    //rock wins
                    document.getElementById("paragraphChoice").innerHTML =
                        "You won! The computer choose "+ computerGuess;                        
                } else {
                    //scissors wins
                    document.getElementById("paragraphChoice").innerHTML =
                        "You lost! The computer choose "+ computerGuess;                        
                }                    
            }

            if (userGuess === "scissors") {                    
                if (computerGuess === "paper") {                        
                    document.getElementById("paragraphChoice").innerHTML = 
                        "You won! The computer choose "+ computerGuess;                        
                } else {                        
                    document.getElementById("paragraphChoice").innerHTML = 
                        "You lost! The computer choose "+ computerGuess;                        
                }                    
            }                
        };        
    </script>        
</body>
</html>

到目前為止我還沒有學習過函數，if 語句非常混亂（這就是我的想法）。

非常感謝您的幫助！

Answer 1

當您得到答案時，您就完成了： if 2===2 then finished 。 不要檢查其他可能性。 所以

if (userGuess === computerGuess) {
    document.getElementById("paragraphChoice").innerHTML = 
        "You tied! The computer choose "+ computerGuess; //Both tied!

    // you are done. return.
    return;
}

如果你不告訴程序你完成了，它會繼續檢查所有其他的if-then塊，最后一個將打印到頁面上。 您必須在每個if then塊中添加一個return 。
