Javascript向计数器加一，然后在特定事件发生后显示

Question

我有一种基于猜谜游戏的 JS 和平，其中计算机选择随机数字，用户尝试猜测该数字。该程序会给用户提示并显示用户的最佳猜测。我想做的是:每次输出这 3 个 if 语句之一时，我希望它为计数器加一。当输出最后一句时，我希望程序显示进行了多少次猜测。

    if(guess < to guess){
    document.getElementById('hint').innerHTML = "The number you are trying to 
    guess is higher";
    document.getElementById('lower').innerHTML = "Best lower guess at the moment " + 
    guess;

    }else if(guess > to guess){
    document.getElementById('hint').innerHTML = "The number you are trying to 
    guess is lower";
    document.getElementById('higher').innerHTML = "Best higher guess at the 
    moment " + guess;

    }else if(guess == to guess){
    document.getElementById('hint').innerHTML = "congratulations! You guessed the right number " + " 
     right number was " + to guess + "<br>"+ "How many guesses it took ";
    document.getElementById('lower').innerHTML = "";
    document.getElementById('higher').innerHTML = "";

Answer 1

增加数字非常简单，只需存储一个名为numberOfGuesses的变量即可:

var numberOfGuesses = 0

您可以将其加 1，如下所示:

猜测数 += 1

您可以使用此功能将猜测次数不断增加 1，直到您准备好完成并显示该数字。
