我如何隨機化我的問題？ 我在別處找不到答案

Question

// create questions
var questions = [
    new Question("Which one is not an object oriented programming language?", ["Java", "C#","C++", "C"], "C"),
    new Question("Which language is used for styling web pages?", ["HTML", "JQuery", "CSS", "XML"], "CSS"),
    new Question("There are ____ main components of object oriented programming.", ["1", "6","2", "4"], "4"),
    new Question("Which language is used for web apps?", ["PHP", "Python", "Javascript", "All"], "All"),
    new Question("MVC is a ____.", ["Language", "Library", "Framework", "All"], "Framework")
];


// create quiz
var quiz = new Quiz(questions);

如何在創建測驗時隨機化 ^^^ [Math.floor(math.random()*]不起作用

Answer 1

嘗試這個：

// create questions
var questions = [
    new Question("Which one is not an object oriented programming language?", ["Java", "C#","C++", "C"], "C"),
    new Question("Which language is used for styling web pages?", ["HTML", "JQuery", "CSS", "XML"], "CSS"),
    new Question("There are ____ main components of object oriented programming.", ["1", "6","2", "4"], "4"),
    new Question("Which language is used for web apps?", ["PHP", "Python", "Javascript", "All"], "All"),
    new Question("MVC is a ____.", ["Language", "Library", "Framework", "All"], "Framework")
];


// create quiz
let randomQuestion = questions[Math.floor(Math.random()*questions.length)]
var quiz = new Quiz(randomQuestion);
