使用 html 标签包装 textarea 内容

Question

I'm using the following form to save text files on server:

<form action="***.php" method="post">
   <textarea class="chrr" name="text" placeholder="Text" required></textarea>
   <button type="submit">SAVE</button>
</form>

With the following javascript code, I correct the textarea input:

const form = document.forms[0];
const string = document.getElementsByClassName("chrr");

form.oninput = () => {
   string[0].value = correct(string[0].value);
};

function correct(string) {
   string = string.replace(/  +/g, ' ');
   string = string.replace(/—|–/g, '-');
   string = string.replace(/‘|’/g, "'");
   string = string.replace(/“|”/g, '"');
   string = string.replace(/…/g, '...');
   return string;
};

Now I would like to wrap every single text line with "p" tags. So, if I paste in the textarea:

First line...
Second line...
Third line...

The text should automatically become:

<p>First line...</p>
<p>Second line...</p>
<p>Third line...</p>

How can I achieve this result with pure JavaScript (no jQuery)?

You can split the string with \n , then map the string to wrap that with the element ( p ). Finally join them:

 var str = `First line... Second line... Third line...`; str = str.split('\n').map(s => `<p>${s}</p>`).join('\n'); console.log(str);
