如何将用户输入的换行符从TextArea保存到数据库？

function saveToDatabase() {
  const textArea = document.getElementById('inputText');
  const text = textArea.value;
  const formattedText = text.replace(/\r?\n/g, '
');

  // 将formattedText发送到服务器，以便将其保存到数据库
}

const express = require('express');
const mysql = require('mysql');
const bodyParser = require('body-parser');

const app = express();
app.use(bodyParser.urlencoded({ extended: false }));

const connection = mysql.createConnection({
  host: 'localhost',
  user: 'your-username',
  password: 'your-password',
  database: 'your-database'
});

connection.connect();

app.post('/save-text', (req, res) => {
  const text = req.body.text;

  connection.query('INSERT INTO your-table (text) VALUES (?)', [text], (error, results) => {
    if (error) {
      console.error(error);
      res.status(500).send('Error saving text to database');
    } else {
      res.send('Text saved to database');
    }
  });
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
