我如何映射对象中的字符串，其中空字符串被视为空行并且每个字符串限制为一行

Question

{
"ptr0": [
    "Interviewer: Nancy Carolyn Camp Foster (NF)",
    "",
    "Interviewee: Edith Mills (EM)",
    "",
    "NF: Well it's kind of interesting to observe how students have turned out who've",
    "gone through Bristow schools. We lose track, we don't really realize and",
    "",
    "Other Persons: Lucy Mae Mills (LM) Unknown Woman (WS)"
        ]
}

我正在尝试在浏览器的 jsx 中映射上述 objecttrans 对象 ptr0，我希望对象中的空字符串被视为空行，并且对象中的每个字符串限制为一行，我正在尝试这样的事情在浏览器 jsx 中显示：

采访者：Nancy Carolyn Camp Foster (NF)

受访者：伊迪丝·米尔斯 (EM)

NF：好吧，观察学生们如何证明谁
有点有趣上过布里斯托学校。我们迷路了，我们没有真正意识到并且

其他人：Lucy Mae Mills (LM) 无名女子 (WS)

我调用脚本组件的组件

<Transcript
                transcript={objecttrans.ptr0.map(pt=>{          
                return   pt               
        })}
        />

成绩单组件

return (
    <>
      <div className="content">
           <p>{props.transcript}</p>
      </div>
    </>
  );

Answer 1

使用换行符将行数组连接成一个字符串：

const text = lines.join('\n');

然后将文本放入 preformatted text element <pre> instead of a paragraph element <p> 中，并根据需要设置样式。

const lines = [
  "Interviewer: Nancy Carolyn Camp Foster (NF)",
  "",
  "Interviewee: Edith Mills (EM)",
  "",
  "NF: Well it's kind of interesting to observe how students have turned out who've",
  "gone through Bristow schools. We lose track, we don't really realize and",
  "",
  "Other Persons: Lucy Mae Mills (LM) Unknown Woman (WS)",
];

const text = lines.join('\n');

document.querySelector('pre').textContent = text;

<pre></pre>

Answer 2

您的代码似乎在执行您希望它执行的操作。如果您的问题是未显示新行，则可以在字符串为空时 return 一个 br 元素。类似于：

objecttrans.ptr0.map(pt => pt || <br />

const Transcript = props => <div className="content">
  <p>{props.transcript}</p>
</div>;


const objecttrans = {
  "ptr0": [
    "Interviewer: Nancy Carolyn Camp Foster (NF)",
    "",
    "Interviewee: Edith Mills (EM)",
    "",
    "NF: Well it's kind of interesting to observe how students have turned out who've",
    "gone through Bristow schools. We lose track, we don't really realize and",
    "",
    "Other Persons: Lucy Mae Mills (LM) Unknown Woman (WS)"
  ]
};

ReactDOM.render(
  <Transcript
    transcript={objecttrans.ptr0.map(pt => pt || <br />)}
  />, document.body
);
