我对 JS 和 HTML5 有点陌生。我正在创建一个简单的测验，只是为了它。我知道需要使每个问题都可以独立于其他问题标记为“正确”。我怎样才能通过 JS，甚至 CSS/HTML5 做到这一点？我觉得我需要更改 jquery 文件，但我对如何做有点困惑。测验非常完美，就像我想要的那样，但是当用户选择答案时，我想显示正确或错误。谢谢!

var checkAnswers = function() {

answers.each(function(i) {

var answerString = answerString + answers[i].value;
});
checkIfCorrect(answerString);
};
var checkIfCorrect = function(theString) {

我不知道我是否理解得很好，但是你用 onChange 事件尝试过吗？首先我建议用你的正确答案创建 JSON 文件，并且在每个复选框之后必须是答案元素。像这样:
jQuery('your-form your-input').on('change', function(e) {
e.preventDefault();
var actualAnswer = (jQuery(this).val() == 'your-correct-answer-in-json') ? 'Correct' : 'Incorrect';
/* add actualAnswer to element, for example with parent and find answer element to actual input */
});
关于javascript - 选择单选按钮并显示正确，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45987643/
