How to generate a wrong answer book for online answering questions

In today's information age, answering questions online has become a common task for many students and educators. Wrong questions have always been one of the problems in the learning process. Many people hope to easily generate a wrong answer book for online answers so that they can better review and master knowledge. This article will introduce how to realize the generation function of online answer error book through programming, and provide specific code examples.

Step one: Build a web interface
Generating an online answer book requires a web interface to display questions and answers. You can use HTML and CSS to design a simple interface to ensure that questions and answers are clearly visible. The following is a simple example:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>生成在线答题错题本</title>
    <style>
        /* 网页样式 */
        body {
            font-family: Arial, sans-serif;
        }
        
        .question {
            font-weight: bold;
        }
        
        .answer {
            margin-left: 20px;
        }
    </style>
</head>
<body>
    <h1>在线答题错题本</h1>
    <div id="questions-container"></div>

    <script src="script.js"></script>
</body>
</html>

Copy after login

Step 2: Prepare question data
In order to facilitate the generation of wrong question books, you need to prepare some question data. You can use JavaScript to define an array containing questions and answers. The following is a simple example:

let questions = [
    {
        question: '1 + 1 = ?',
        answer: '2'
    },
    {
        question: '5 + 3 = ?',
        answer: '8'
    },
    // 其他题目...
];

Copy after login

Step 3: Generate questions
After the web page is loaded, use JavaScript to dynamically add the question data to the web page. The following is a simple example:

window.onload = function() {
    let questionsContainer = document.getElementById('questions-container');

    for (let i = 0; i < questions.length; i++) {
        let questionDiv = document.createElement('div');
        questionDiv.classList.add('question');
        questionDiv.textContent = questions[i].question;

        let answerDiv = document.createElement('div');
        answerDiv.classList.add('answer');
        answerDiv.textContent = '答案：' + questions[i].answer;

        questionsContainer.appendChild(questionDiv);
        questionsContainer.appendChild(answerDiv);
    }
};

Copy after login

Step 4: Add wrong question recording function
In order to facilitate students to record wrong questions, a button can be added to mark wrong questions when answering questions. The following is a simple example:

<button onclick="markAsWrong(0)">错题</button>

Copy after login

function markAsWrong(index) {
    let questionDiv = document.getElementsByClassName('question')[index];
    questionDiv.style.color = 'red';
}

Copy after login

Through the above steps, we can implement a simple error book generation function for online answering questions. When answering questions, students can click the button to mark wrong questions, and the corresponding questions on the web page will turn red. Students can review and strengthen their knowledge based on the generated wrong question books.

It should be noted that the above example is a very simple implementation, and actual applications may require more functions and complete design. I hope the above content will be helpful to you, and I wish you good results in your studies!
