<script src="https://surveyjs.azureedge.net/1.8.0/survey.js"></script>
<link href="https://surveyjs.azureedge.net/1.8.0/survey.css" rel="stylesheet" />

npm install mysql2

const mysql = require('mysql2');

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

Survey.dxSurveyService.serviceUrl = 'api/MySurvey'; // 替换为实际的后端API URL

const survey = new Survey.Model(surveyJson);

survey.onComplete.add(function (sender) {
  const jsonData = JSON.stringify(sender.data); // 将调查问卷数据转换为JSON字符串

  connection.query('INSERT INTO surveys SET data = ?', [jsonData], function (error, results, fields) {
    if (error) {
      console.error(error);
      return;
    }

    console.log('Survey data saved to MySQL database!');
  });
});

Survey.defaultBootstrapCss.navigationButton = 'btn btn-primary';

$("#surveyContainer").Survey({
  model: survey
});
