Question

我想做的是制作一个简单的猜谜游戏，用户可以无限制地使用任何数字，但是当根据他们的猜测数量正确猜出数字时，将在最后评分。但是，当我输入一个数字并按下按钮多次时，我的代码会从＆＃34;更高＆＃34;到＆＃34;降低＆＃34;即使数字没有改变，也没有显示正确猜测数字时应显示的消息。这是我的代码，我是初学者，因此必然会出现代码中的错误，并感谢任何帮助。

<fieldset>
    <input type="number" id="guess" />
    <button onClick="checknum();">Check Number</button>
</fieldset>

<fieldset>  
    <p>Your current status:</p>
    <output id="status_output">You have yet to guess anything.</output>
</fieldset> 

<script type="text/javascript">

    function checknum(){

        var randomNumber = Math.floor((Math.random() * 100) + 1);
        var guessNumber = document.getElementById("guess").value;
        //var guessNumber = parseInt(guess.value);
        var statusOutput = document.getElementById('status_output');
        var counter = 0;    
        var isguessed = false;

        do {
            counter = (counter + 1)
            if (guessNumber < randomNumber) {
                statusOutput.value = ("Higher");
            }
            else if (guessNumber > randomNumber) {
                statusOutput.value = ("Lower");
            }
            else if (guessNumber = randomNumber) {
                set (isguessed = true());
                statusOutput.value = ("Correct" + mark());
            }
        }
        while (isguessed = false);
    }

    function mark(){
        if (counter < 10){
            statusOutput.value("Excellent");
        }
        else if (counter > 10 && counter <20){
            statusOutput.value("Okay");
        }
        else 
            statusOutput.value("Needs Practice");
    }

</script>

Answer 1

在您为名为isguessed的变量赋值false时。您希望改为while (isguessed === false)。这将检查isguessed是否设置为false

isguessed = false：指定varibles isguessed为false

isguessed === false：布尔表达式返回true或false
