如何创建在不同页面上有不同问题的测验？

Question

I want to create a small quiz at the end of each of page. I have a quiz written on JavaScript but I want different questions to appear in different pages. In a few words, I want the const myQuestions to change if i am on different pages. How can I achieve this?

I already tried with if statements but I couldn't achieve what I want. Any help would be greatly appreciated!

This is the JS code of the quiz

(function() {

  const myQuestions = [
    {
      question: "question 1?",
      answers: {
        a: "one",
        b: "two",
        c: "three"
      },
      correctAnswer: "c"
    },
    {
      question: "question 2?",
      answers: {
        a: "one",
        b: "two",
        c: "three"
      },
      correctAnswer: "c"
    },
    {
      question: "question 3?",
      answers: {
        a: "one",
        b: "two",
        c: "three"
        d: "four"
      },
      correctAnswer: "d"
    }
  ];



  function buildQuiz() {
    // we'll need a place to store the HTML output
    const output = [];

    // for each question...
    myQuestions.forEach((currentQuestion, questionNumber) => {
      // we'll want to store the list of answer choices
      const answers = [];

      // and for each available answer...
      for (letter in currentQuestion.answers) {
        // ...add an HTML radio button
        answers.push(
          `<label>
             <input type="radio" name="question${questionNumber}" value="${letter}">
              ${letter} :
              ${currentQuestion.answers[letter]}
           </label>`
        );
      }

      // add this question and its answers to the output
      output.push(
        `<div class="slide">
           <div class="question"> ${currentQuestion.question} </div>
           <div class="answers"> ${answers.join("")} </div>
         </div>`
      );
    });

    // finally combine our output list into one string of HTML and put it on the page
    quizContainer.innerHTML = output.join("");
  }

  function showResults() {
    // gather answer containers from our quiz
    const answerContainers = quizContainer.querySelectorAll(".answers");

    // keep track of user's answers
    let numCorrect = 0;

    // for each question...
    myQuestions.forEach((currentQuestion, questionNumber) => {
      // find selected answer
      const answerContainer = answerContainers[questionNumber];
      const selector = `input[name=question${questionNumber}]:checked`;
      const userAnswer = (answerContainer.querySelector(selector) || {}).value;

      // if answer is correct
      if (userAnswer === currentQuestion.correctAnswer) {
        // add to the number of correct answers
        numCorrect++;

        // color the answers green
        answerContainers[questionNumber].style.color = "lightgreen";
      } else {
        // if answer is wrong or blank
        // color the answers red
        answerContainers[questionNumber].style.color = "red";
      }
    });

    // show number of correct answers out of total
    resultsContainer.innerHTML = `${numCorrect} out of ${myQuestions.length}`;
  }

  function showSlide(n) {
    slides[currentSlide].classList.remove("active-slide");
    slides[n].classList.add("active-slide");
    currentSlide = n;

    if (currentSlide === 0) {
      previousButton.style.display = "none";
    } else {
      previousButton.style.display = "inline-block";
    }

    if (currentSlide === slides.length - 1) {
      nextButton.style.display = "none";
      submitButton.style.display = "inline-block";
    } else {
      nextButton.style.display = "inline-block";
      submitButton.style.display = "none";
    }
  }

  function showNextSlide() {
    showSlide(currentSlide + 1);
  }

  function showPreviousSlide() {
    showSlide(currentSlide - 1);
  }

  const quizContainer = document.getElementById("quiz");
  const resultsContainer = document.getElementById("results");
  const submitButton = document.getElementById("submit");

  // display quiz right away
  buildQuiz();

  const previousButton = document.getElementById("previous");
  const nextButton = document.getElementById("next");
  const slides = document.querySelectorAll(".slide");
  let currentSlide = 0;

  showSlide(0);

  // on submit, show results
  submitButton.addEventListener("click", showResults);
  previousButton.addEventListener("click", showPreviousSlide);
  nextButton.addEventListener("click", showNextSlide);
})();

Mileage may vary, depends on what you want to do. With just javascript, you could pass windows.location.pathname to your function each time it's called and choose the appropriate object of questions related to the path you need.

if (windows.location.pathname).includes('page1') {
  let currentQuestion = myQuestions[0]
} 
//...rest of the logic
