How to design a simple online question answering interface
How to design a simple online question answering interface requires specific code examples
With the rapid development of the Internet and information technology, online answering questions has become a way for people to study and take exams. One of the important ways. Designing a simple online question answering interface can help users learn and test effectively. This article will introduce the design process of a simple online question answering interface and provide specific code examples.
1. Interface layout design
A good interface layout can improve the user experience and efficiency. In the design of the answer interface, a three-column layout is usually used. The left column is used to display the question list, the middle column is used to display the details and options of the current question, and the right column is used to display the answers and statistical information of the questions the user has done. The specific code examples are as follows:
<!DOCTYPE html>
<html>
<head>
<title>在线答题</title>
<style>
.sidebar {
float: left;
width: 20%;
padding: 10px;
}
.content {
float: left;
width: 60%;
padding: 10px;
}
.status {
float: left;
width: 20%;
padding: 10px;
}
</style>
</head>
<body>
<div class="sidebar">
<!-- 题目列表 -->
</div>
<div class="content">
<!-- 当前题目的详细内容和选项 -->
</div>
<div class="status">
<!-- 答题情况和答题统计信息 -->
</div>
</body>
</html>2. Question list design
The question list is used to display all questions. The user can click on the questions in the list to switch the currently displayed question content. When designing a question list, an unordered list is usually used and a click event is set for each list item. When the user clicks on a list item, the current question content is switched. The specific code examples are as follows:
<div class="sidebar">
<ul id="question-list">
<li><a href="#" onclick="changeQuestion(1)">题目1</a></li>
<li><a href="#" onclick="changeQuestion(2)">题目2</a></li>
<li><a href="#" onclick="changeQuestion(3)">题目3</a></li>
</ul>
</div>
<script>
function changeQuestion(questionId) {
// 根据题目id获取对应的题目内容和选项
// 更新题目内容和选项的显示
}
</script>3. Question content and option design
The question content and options are used to display the detailed content and options of the current question for users to choose answers. When designing question content and options, a form is usually used and a radio or multi-select box is set for each option in the form. The specific code examples are as follows:
<div class="content">
<h2 id="题目标题">题目标题</h2>
<form id="question-form">
<input type="radio" name="option" value="A"> 选项A <br>
<input type="radio" name="option" value="B"> 选项B <br>
<input type="radio" name="option" value="C"> 选项C <br>
<input type="radio" name="option" value="D"> 选项D <br>
<input type="button" value="提交" onclick="submitAnswer()">
</form>
</div>
<script>
function submitAnswer() {
// 获取用户选择的答案
// 根据用户答案判断对错
// 更新答题情况和答题统计信息显示
}
</script>4. Answering situation and answering statistical information design
Answering situation and answering statistical information are used to display the answering situation and answering statistical information that the user has done. When designing to display the answer status, an ordered list is usually used, and a style is set for each list item to represent the user's answer status. When designing to display answer statistics, a table is usually used to display the total number of answers, the number of correct answers, and the number of wrong answers. The specific code examples are as follows:
<div class="status">
<h3 id="答题情况">答题情况</h3>
<ol id="answer-list">
<!-- 用户答题情况 -->
</ol>
<h3 id="答题统计">答题统计</h3>
<table id="answer-statistics">
<tr>
<th>总数</th>
<th>正确</th>
<th>错误</th>
</tr>
<tr>
<td id="total-count">0</td>
<td id="correct-count">0</td>
<td id="wrong-count">0</td>
</tr>
</table>
</div>
<script>
function submitAnswer() {
// 获取用户选择的答案
// 根据用户答案判断对错
// 更新答题情况和答题统计信息显示
// 更新题目列表中当前题目的样式
}
</script>Through the above code examples, we can implement a simple online question answering interface. When the user clicks on the question list, the currently displayed question content and options are switched. When the user selects an answer and clicks the submit button, it determines whether it is right or wrong based on the user's answer, and updates the display of answer status and answer statistics. In this way, users can easily answer questions online. Of course, the above is just a simple example, and the actual online question answering interface may require more functions and interaction design to meet actual needs.
