如何在EJS中通过MySQL值显示不同的块？

const express = require('express');
const ejs = require('ejs');
const mysql = require('mysql');

const connection = mysql.createConnection({
  host: 'localhost',
  user: 'root',
  password: 'password',
  database: 'database_name'
});

connection.connect((err) => {
  if (err) throw err;
  console.log('Connected to MySQL database');
});

const app = express();

app.set('view engine', 'ejs');

app.get('/', (req, res) => {
  connection.query('SELECT * FROM table_name', (err, results) => {
    if (err) throw err;
    res.render('index', { data: results });
  });
});

<% data.forEach((item) => { %>
  <% if (item.value === 'value1') { %>
    <div>Block 1</div>
  <% } else if (item.value === 'value2') { %>
    <div>Block 2</div>
  <% } else { %>
    <div>Default Block</div>
  <% } %>
<% }) %>
