In the field of education and training, online question answering has become a commonly used tool. By answering questions online, students can study and test conveniently, and teachers and trainers can better understand students' learning progress and ability levels. However, simply providing a question-answering function does not fully meet the needs of users.

Use JavaScript to write code: Use JavaScript to write code to connect the answer result data and the interface to achieve a visual display of answer results.

3. Example code example
The following is a simple code example that demonstrates how to achieve a visual display of answer scores:

HTML code:

<!DOCTYPE html>
<html>
<head>
    <title>答题成绩</title>
    <link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
    <h1>答题成绩</h1>
    <div id="result"></div>
    <script src="script.js"></script>
</body>
</html>

CSS code (style.css):

body {
    font-family: Arial, sans-serif;
}

h1 {
    text-align: center;
}

#result {
    width: 500px;
    height: 200px;
    margin: 0 auto;
    border: 1px solid #ccc;
    padding: 20px;
}

JavaScript code (script.js):

var correctAnswers = 8; // 正确答题数量
var wrongAnswers = 2; // 错误答题数量
var unansweredQuestions = 0; // 未答题数量

var score = correctAnswers * 10; // 每题10分

var resultDiv = document.getElementById("result");
resultDiv.innerHTML = "正确答题数量：" + correctAnswers +
                      "<br>错误答题数量：" + wrongAnswers +
                      "<br>未答题数量：" + unansweredQuestions +
                      "<br>得分：" + score;

Running the above code will display a simple answer score interface in the browser, showing Statistics and scores of answer results.
