JavaScript：将伪代码转换为 JavaScript 代码

Question

JavaScript

我考虑过以下伪代码：

for answer in answers {
    if(answer in selectedAnswers){
        if(selectedAnswer in rightAnswers)
             // Code if answer is right
        }    
        else {
            // Code if answer is wrong
        }
    }
}

我尝试在 JavaScript 中实现代码，但不知何故我不想成功。

currentAnswers = Object.keys(currentQuestion.answers);
currentSelectedAnswers[buttonClicked] = this.id.split('-')[5]; 
currentRightAnswers = currentQuestion.rights;

    for(var answer in currentAnswers) 
    {
        if(currentSelectedAnswers.includes(answer))
        {
            if(currentRightAnswers.includes(currentSelectedAnswers))
            {
                console.log("TRUE");
            }
            else 
            { 
                console.log("FALSE");
            } 
        }
    }


A snippet of a question of my JSON File:

                    "answers": {
                        "1": '...sind eigenständig ausführbare Programme.',
                        "2": '...müssen in der gleichen Programmiersprache wie die Anwendung geschrieben worden sein.',
                        "3": '...müssen in Assemblersprache geschrieben worden sein.',
                        "4": '...können beim Compilieren des Programms statisch gelinkt werden.',
                        "5": '...können zur Laufzeit des Programms dynamisch gelinkt werden.',
                        "6": '...müssen zum Compilieren des Programms im Quelltext vorliegen.'
                    },
                    "rights": {
                        "1": "4",
                        "2": "5" 
                    },

但我收到以下错误：

我希望有人可以帮助我吗？

我想突出显示两个正确答案并突出显示选定的两个错误答案。

currentAnswers 在顶部的任何函数中声明......

currentSelectedAnswers 在应答按钮的 buttonClick 事件中声明，如果我单击应答按钮，则带有 for 循环的函数将执行...

currentRightAnswers 在函数中声明，其顶部有 for 循环......

THE VALIDATION FUNCTION WHICH CHECK IF THE ANSWERS ARE WRONG OR RIGHT
var currentSelectedAnswers = [];
var currentAnswers = [];
var currentAnswers = Object.keys(currentQuestion.answers);

function validateEasyTwoAnswersQuestionAnswer() {
    console.log("validateEasyTwoAnswersQuestionAnswer");
    $(".answer-btn").hide();
    var currentRightAnswers = [];
    currentRightAnswers = currentQuestion.rights;
    for(var answer in currentAnswers) 
    {
        if(currentSelectedAnswers.includes(answer))
        {
            if(currentRightAnswers.includes(currentSelectedAnswers))
            {
                console.log("TRUE");
            }
            else 
            { 
                console.log("FALSE");
            } 
        }
    }
    $(".continue-btn").show();
}



IF AN ANSWER CLICKED THE CLICK EVENT WILL EXECUDE
button.addEventListener("click", function(e) {
            if(buttonClicked == 2)
            {
              e.preventDefault();
            }
            else {
                buttonClicked++;
                selectAnswer(this);
                console.log(this.id);
                currentSelectedAnswers[buttonClicked] = this.id.split('-')[5];
                console.log(currentSelectedAnswers);
            }
        });

currentRightAnswers.includes 不是函数

我相信您正在尝试调用函数Array.prototype.includes。它是 Array 对象的一部分，但 currentRightAnswers 不是数组。它只是一个对象。

快速解决方法是将属性rights 定义为Array，就像这样，在您的JSON 文件中（注意[] 而不是{}：

{
  "answers": {
    "1": '...sind eigenständig ausführbare Programme.',
    "2": '...müssen in der gleichen Programmiersprache wie die Anwendung geschrieben worden sein.',
    "3": '...müssen in Assemblersprache geschrieben worden sein.',
    "4": '...können beim Compilieren des Programms statisch gelinkt werden.',
    "5": '...können zur Laufzeit des Programms dynamisch gelinkt werden.',
    "6": '...müssen zum Compilieren des Programms im Quelltext vorliegen.'
  },
  "rights": [
    "4",
    "5" 
  ]
}
