以下是我的代码

    
    var indents = [];

    for (var i = 0; i < questions.length; i++) {

        indents.push(<span><p>问题: {[questionWrongSelection[i], `你的答案: ${wrongAnswer[i]}`, `正确答案:\n ${rightAnswer[i]}`]}</p></span>);
    }

这是 div 的样式-

    <div className='wrongselection'>
        <hr />
        <h3>错误答案</h3>
        <p>
            <p>
                {indents.map(indent=><div>{indent}</div>)}
            </p>
        </p>
    </div>
我尝试使用 .map 方法但由于某种原因它对我不起作用或者我可能使用方法不对任何帮助将不胜感激

英文:

I am creating a quiz app. I want to display result as follows

> Question:
Your Answer:
Correct answer:

But currently my code is displaying in a line like this (please see image link to view actual results):-

>Question: Your Answer: Correct Answer:
Image Link: https://ibb.co/30v89qS

below is my code

var indents = [];
for (var i = 0; i < questions.length; i++) {
indents.push(<span><p>Question: {[questionWrongSelection[i], `Your Answer: ${wrongAnswer[i]}`, `Correct Answer:\n ${rightAnswer[i]}`]}</p></span>);
}

And this is how the div looks:-

<div className='wrongselection'>
<hr />
<h3>Wrong Answers</h3>
<p>
<p>
{indents.map(indent=><div>{indent}</div>)}
</p>
</p>
</div>

I tried .map method but for some reason it is not working for me or may be I am using it in a wrong way. Any help will be highly appreciated.

只需将每个单独的<p>标签中的内容括起来。

var indents = [];
for (var i = 0; i < questions.length; i++) {
indents.push(
<span>
<p>问题:{questionWrongSelection[i]}</p>
<p>你的答案:{wrongAnswer[i]} </p>
<p>正确答案:{rightAnswer[i]}</p>
</span>
);
}
英文:

Just enclose the contents on each separate <p> tags.

var indents = [];
for (var i = 0; i < questions.length; i++) {
indents.push(
<span>
<p>Question: {questionWrongSelection[i]}</p>
<p>Your Answer: {wrongAnswer[i]} </p>
<p>Correct Answer: {rightAnswer[i]}</p>
</span>
);
}

答案2

得分: 0

var indents = [];

for (var i = 0; i < questions.length; i++) {
  indents.push(
    <div className="result">
      <div>
        <strong>Question:</strong> {questionWrongSelection[i]}
      </div>
      <div>
        <strong>Your Answer:</strong> {wrongAnswer[i]}
      </div>
      <div>
        <strong>Correct Answer:</strong> {rightAnswer[i]}
      </div>
    </div>
  );
}

每个问题、答案和正确答案都包含在类名为 "result" 的

中。然后,您可以应用以下 CSS 样式以实现列布局:

.result {
  display: flex;
  flex-direction: column;
  margin-bottom: 10px;
}

.result div {
  margin-bottom: 5px;
}

请确保在您的组件中包括这些 CSS 样式,或者将其放入一个单独的 CSS 文件中,然后在您的组件中进行导入。display: flex; 属性与 flex-direction: column; 创建了结果的列布局,而 margin-bottom 属性为每个结果之间添加了一些间距。

最后,在您的组件中渲染 indents 数组:

return <div>{indents}</div>;

希望这对您有所帮助!


<details>
<summary>英文:</summary>

var indents = [];

for (var i = 0; i < questions.length; i++) {
indents.push(
<div className="result">
<div>
<strong>Question:</strong> {questionWrongSelection[i]}
</div>
<div>
<strong>Your Answer:</strong> {wrongAnswer[i]}
</div>
<div>
<strong>Correct Answer:</strong> {rightAnswer[i]}
</div>
</div>
);
}

 each question, answer, and the correct answer is wrapped inside a &lt;div&gt; with the class name &quot;result&quot;. You can then apply CSS styles to achieve the column layout
css below - 

.result {
display: flex;
flex-direction: column;
margin-bottom: 10px;
}

.result div {
margin-bottom: 5px;
}

Make sure to include the CSS styles in your component or in a separate CSS file that is imported into your component. The display: flex; property with flex-direction: column; creates a column layout for the results, and the margin-bottom properties add some spacing between each result.
Finally, render the indents array in your component:

return <div>{indents}</div>;


Hope this will help!!
