javascript输入字段返回"；关于；而不是控制台中的值

我在JavaScript中遇到问题。 我想在提交表单时从一系列单选按钮中获取值。
但是我总是在上得到

的值，而不是应该是“A”、“B”或“C”的值，我不知道它为什么会这样

这是js

const questionContainer = document.querySelector('#js-question-container');

const quizz = document.querySelector('.js-quizz');

const result = document.querySelector('.js-score');

const getQuestions = (callback) => {
    const request = new XMLHttpRequest();
    request.addEventListener('readystatechange', (() => {
        // console.log(request, request.readyState);
        if (request.readyState === 4 && request.status === 200) {
            const data = JSON.parse(request.responseText);
            callback(undefined, data);

        } else if (request.readyState === 4) {
            callback("Les données n'ont pas pu etre chargées", undefined);
        }

    }))
    request.open('GET', './questions.json');
    request.send();
}

getQuestions((err, data) => {
    console.log('callback fired !');
    console.log(err, data);

    let output = '';
    data.forEach(question => {
        output += `<p class="lead">${question.title}</p>`;
        question.answers.forEach(answer => {
            output += `<div class="form-check ${answer.value}">
            <input type="radio" class="form-radio answer${question.id}" name="q${question.id}" "value=${answer.value} ${shouldBeChecked(answer.id)}>
                <label class="form-check-label" for= "q${question.id}">${answer.sentence}</label>
        </div >`;
        });
        questionContainer.innerHTML = output;
        tryToDelegate();
        formSubmission(question);
    })
});

const formSubmission = (question) => {

    quizz.addEventListener('submit', e => {
        e.preventDefault();
        let score = 0;
        const userAnswers = [quizz.q0.value, quizz.q1.value, quizz.q2.value, quizz.q3.value];

        console.log('useranswers',userAnswers[3]);
        const correctAnswers = ["A", "B", "B", "B"];
        const nbQuestions = correctAnswers.length;
        let commentText = document.querySelector('.js-comment-text');

        userAnswers.forEach((answer, index) => {
            if (answer === correctAnswers[index]) {
                score += 1 / nbQuestions;
            }
            console.log('answer',answer, score);
            result.classList.remove('d-none');
            switch (score * 100) {
                case 0:
                    commentText.textContent = "Flatten by the ninja";
                    scrollToTop();
                    break;
                case 25:
                    commentText.textContent = "That's a pity score, please improve !";
                    scrollToTop();
                    break;
                case 50:
                    commentText.textContent = "On the way to the success !";
                    scrollToTop();
                    break;
                case 75:
                    commentText.textContent = "You nearly beat the ninja !";
                    scrollToTop();
                    break;
                case 100:
                    commentText.textContent = "The ninja is KO !";
                    scrollToTop();
                    break;
                default:
                    commentText.textContent = '';
            }

            let outputScore = 0;
            const timer = setInterval(() => {
                result.querySelector('.js-score-inner').innerHTML = `Your score is < span class="display-4 text-primary" > ${outputScore} %</span > `;
                if (outputScore === (score * 100)) {
                    clearInterval(timer)
                } else {
                    outputScore++;
                }

            }, 10);
        });
    })
}

let scrollToTop = () => {
    const topXOffset = document.querySelector('#top').offsetLeft;
    const topYOffset = document.querySelector('#top').offsetTop;

    window.scrollTo(topXOffset, topYOffset);
}
const tryToDelegate = () => {
    quizz.querySelectorAll('.form-check').forEach(item => {
        item.addEventListener('click', () => {
            item.querySelector('input[type="radio"]').setAttribute('checked', 'checked');
            var el = item.nextElementSibling;
            console.log(el);
        });
    })
}
const shouldBeChecked = element => {
    if (element === 0) {
        return 'checked';
    } else {return '';}
}

const questionContainer=document.querySelector（“#js questionContainer”）；
const quizz=document.querySelector（'.js quizz'）；
const result=document.querySelector（'.js score'）；
const getQuestions=（回调）=>{
const request=new XMLHttpRequest（）；
request.addEventListener（'readystatechange'，（（）=>{
//日志（request，request.readyState）；
if（request.readyState==4&&request.status==200）{
const data=JSON.parse（request.responseText）；
回调（未定义，数据）；
}else if（request.readyState==4）{
回调（“未定义的不可撤销的交易”）；
}
}))
open（'GET'，'./questions.json'）；
request.send（）；
}
getQuestions（（错误，数据）=>{
log（'callback fired！'）；
console.log（错误、数据）；
让输出=“”；
data.forEach（问题=>{
输出+=`
${question.title}
`；
问题.答案.forEach（答案=>{
输出+=`
对我来说，在第34行，你有问题

name=“q${question.id}”value=${answer.value}${shouldbecked（answer.id）}-值中存在问题

name=“q${question.id}”value=“${answer.value}${shouldbecked（answer.id）”}应该是
Post您的代码或部分代码，而不是github url“我不知道它为什么会这样。”-因为
上的
是单选按钮使用的默认值，如果您没有明确指定不同的值。并且通过弄乱value属性周围部分的语法，实际上您没有指定值。@04FS。好的，我知道了，只是额外的双引号弄乱了我的代码。我应该买新眼镜：）
