How to implement the interactive question (fill-in-the-blank, question-and-answer, etc.) function in online answering requires specific code examples

With the popularity of the Internet and the development of online education With the rise of online education, more and more people choose to answer questions online to test their knowledge. In addition to single-choice questions and multiple-choice questions, interactive questions (such as fill-in-the-blank questions, quiz questions, etc.) have gradually become a common form of online answering questions. This article will introduce how to implement the function of interactive questions through code to help everyone better understand and learn.
Before implementing the function of interactive questions, we first need to clarify the characteristics and requirements of interactive questions. Interactive questions mainly include fill-in-the-blank questions and quiz questions. For fill-in-the-blank questions, users need to fill in the answers in the given spaces. For quiz questions, users need to enter text to answer the question. Therefore, realizing the function of interactive questions requires consideration of user input, answer judgment, and result display.

1. Implementation of fill-in-the-blank questions
Fill-in-the-blank questions require users to fill in the answers in the given blanks, and can judge the answers filled in by the users. The following is an example of how to implement a fill-in-the-blank question:

<div>
  <label for="answer">请填写下面句子中的空格：</label>
  <input type="text" id="answer">
  <button onclick="checkBlank()">提交答案</button>
</div>

<script>
  function checkBlank() {
    var answer = document.getElementById("answer").value;
    if (answer === "答案") {
      alert("回答正确！");
    } else {
      alert("回答错误，请重新填写！");
    }
  }
</script>

In the above example, we implement a user input box through the input element of HTML, and the user can fill in the answer in the input box. Through the JavaScript function checkBlank(), we obtain the filled-in answers and make judgments. If the answer is correct, a prompt for a correct answer will pop up, otherwise a prompt for an incorrect answer will pop up.

2. Implementation of Questions and Answers
Questions and Answers require the user to answer a question and be able to judge the user's answer. The following is an example of how to implement a question and answer question:

<div>
  <label for="answer">请回答下面的问题：</label>
  <textarea id="answer"></textarea>
  <button onclick="checkAnswer()">提交答案</button>
</div>

<script>
  function checkAnswer() {
    var answer = document.getElementById("answer").value;
    if (answer === "答案") {
      alert("回答正确！");
    } else {
      alert("回答错误，请重新回答！");
    }
  }
</script>

In the above example, we implement a multi-line text box through the textarea element of HTML, and users can answer questions in the text box. Through the JavaScript function checkAnswer(), we obtain the user's answer and make a judgment. If the answer is correct, a prompt for a correct answer will pop up, otherwise a prompt for an incorrect answer will pop up.

3. Display of interactive questions and judgment of results
In addition to user input and answer judgment, interactive questions also need to display the questions and judge the results of user answers. The following is a complete implementation example of an interactive question:

<div>
  <label for="answer">请填写下面句子中的空格：</label>
  <input type="text" id="answer">
  <button onclick="checkBlank()">提交答案</button>
</div>

<script>
  function checkBlank() {
    var answer = document.getElementById("answer").value;
    if (answer === "答案") {
      document.getElementById("result").innerHTML = "回答正确！";
    } else {
      document.getElementById("result").innerHTML = "回答错误，请重新填写！";
    }
  }
</script>

<div id="result"></div>

In the above example, we implemented a container for displaying results through the div element. Through the JavaScript function checkBlank(), we obtain the filled-in answers and make judgments. If the answer is correct, a prompt for a correct answer is displayed in the results container, otherwise a prompt for an incorrect answer is displayed.

Through the above examples, we can see that implementing the function of interactive questions is relatively simple and intuitive. Through reasonable layout and logical judgment, we can realize functions such as user input, answer judgment, and result display, improving the interactivity and practicality of online answering questions. At the same time, in order to provide a better user experience, we can also consider adding some other functions, such as reset buttons, display answers, etc., to meet users' learning needs.

I hope this article can help everyone realize the interactive question function in online answering, and at the same time, it can also inspire more people to explore and innovate in online education and Internet technology.
