如何在Javascript/HTML中存储输入值

localStorage.setItem('inputValue', inputValue);

var storedValue = localStorage.getItem('inputValue');

document.cookie = "inputValue=" + inputValue;

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

sessionStorage.setItem('inputValue', inputValue);
// 或
localStorage.setItem('inputValue', inputValue);

var storedValue = sessionStorage.getItem('inputValue');
// 或
var storedValue = localStorage.getItem('inputValue');

// 连接数据库
var mysql = require('mysql');
var connection = mysql.createConnection({
  host: '数据库主机地址',
  user: '数据库用户名',
  password: '数据库密码',
  database: '数据库名'
});
connection.connect();

// 存储输入值
var sql = "INSERT INTO input_values (value) VALUES (?)";
connection.query(sql, [inputValue], function (error, results, fields) {
  if (error) throw error;
  console.log('Stored input value successfully');
});

// 获取存储的值
var sql = "SELECT value FROM input_values";
connection.query(sql, function (error, results, fields) {
  if (error) throw error;
  var storedValue = results[0].value;
  console.log('Retrieved input value:', storedValue);
});

// 断开数据库连接
connection.end();
