如何从与 JavaScript (JSON) 在同一行的另一个值中找到值？

Question

我正在尝试从数字中获取“correctAnswers”。

这里是 JSON:

的样本

{
  "questions": [
    {
      "number": 3,
      "question": "☀️ ➕  = ?",
      "answers": [
        "sunflower",
        "BIRTHDAY",
        "iPhone",
        "MOON CAKE"
      ],
      "correctAnswers": [
        "sunflower"
      ],
      "random": true,
      "timeLimit": "24"
    },
    {
      "number": 1,
      "question": "⭐️ ➕  =❓ ",
      "answers": [
        "STAR FISH",
        "iPhone",
        "MOON CAKE",
        "HOT DOG"
      ],
      "correctAnswers": [
        "STAR FISH"
      ],
      "random": true,
      "timeLimit": "20"
    },
    {
      "number": 7,
      "question": " ➕ ☎ = ",
      "answers": [
        "SUNGLASSES",
        "SUNFLOWER",
        "HOUSEPAINT",
        "IPHONE"
      ],
      "correctAnswers": [
        "IPHONE"
      ],
      "random": true,
      "timeLimit": 15
    },
  ]
}

我试图在“问题”中找到“数字”:1 或随机数，然后从该数字中找到“正确答案”。

Answer 1

const array = {
  "questions": [
    {
      "number": 3,
      "question": "☀️ ➕  = ?",
      "answers": [
        "sunflower",
        "BIRTHDAY",
        "iPhone",
        "MOON CAKE"
      ],
      "correctAnswers": [
        "sunflower"
      ],
      "random": true,
      "timeLimit": "24"
    },
    {
      "number": 1,
      "question": "⭐️ ➕  =❓ ",
      "answers": [
        "STAR FISH",
        "iPhone",
        "MOON CAKE",
        "HOT DOG"
      ],
      "correctAnswers": [
        "STAR FISH"
      ],
      "random": true,
      "timeLimit": "20"
    },
    {
      "number": 7,
      "question": " ➕ ☎ = ",
      "answers": [
        "SUNGLASSES",
        "SUNFLOWER",
        "HOUSEPAINT",
        "IPHONE"
      ],
      "correctAnswers": [
        "IPHONE"
      ],
      "random": true,
      "timeLimit": 15
    },
  ]
};

const { questions } = array;

// Find by number
const correctAnswersByNumber = qNumber => {
  const q = questions.find(({ number }) => number === qNumber);
  if (!q) {
    return false;
  }

  return q.correctAnswers;
};
console.log(correctAnswersByNumber(3)); // Question by number === 3

// Random question
const randomCorrectAnswers = questions[Math.floor(Math.random() * questions.length)].correctAnswers;
console.log(randomCorrectAnswers);

Answer 2

使用随机选择一个随机问题。然后显示正确的属性。

var data = {
  "questions": [
    {
      "number": 3,
      "question": "☀️ ➕  = ?",
      "answers": [
        "sunflower",
        "BIRTHDAY",
        "iPhone",
        "MOON CAKE"
      ],
      "correctAnswers": [
        "sunflower"
      ],
      "random": true,
      "timeLimit": "24"
    },
    {
      "number": 1,
      "question": "⭐️ ➕  =❓ ",
      "answers": [
        "STAR FISH",
        "iPhone",
        "MOON CAKE",
        "HOT DOG"
      ],
      "correctAnswers": [
        "STAR FISH"
      ],
      "random": true,
      "timeLimit": "20"
    },
    {
      "number": 7,
      "question": " ➕ ☎ = ",
      "answers": [
        "SUNGLASSES",
        "SUNFLOWER",
        "HOUSEPAINT",
        "IPHONE"
      ],
      "correctAnswers": [
        "IPHONE"
      ],
      "random": true,
      "timeLimit": 15
    },
  ]
};


// Let's choose a random question
let question = data['questions'][Math.floor(Math.random() * data['questions'].length)];


console.log(question.question, question.correctAnswers)

如何从与 JavaScript (JSON) 在同一行的另一个值中找到值？

How can I find the value from another value in the same line with JavaScript (JSON)?
