如何保存片段onButtonClick并在下一次程序启动时加载

localStorage.setItem('buttonClickData', JSON.stringify(data));

var savedData = JSON.parse(localStorage.getItem('buttonClickData'));

document.cookie = "buttonClickData=" + JSON.stringify(data);

var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
  var cookie = cookies[i].trim();
  if (cookie.indexOf('buttonClickData=') === 0) {
    var savedData = JSON.parse(cookie.substring('buttonClickData='.length, cookie.length));
    break;
  }
}

// 假设已经连接到MySQL数据库
var sql = "INSERT INTO buttonClickData (data) VALUES (?)";
connection.query(sql, [JSON.stringify(data)], function (error, results, fields) {
  if (error) throw error;
  console.log('Data saved successfully');
});

// 假设已经连接到MySQL数据库
var sql = "SELECT data FROM buttonClickData ORDER BY id DESC LIMIT 1";
connection.query(sql, function (error, results, fields) {
  if (error) throw error;
  var savedData = JSON.parse(results[0].data);
});
