js转换string转时间戳

// 示例字符串
let dateString = "2023-10-05T14:48:00.000Z";

// 使用Date.parse()方法
let timestamp = Date.parse(dateString);
console.log(timestamp); // 输出: 1696507680000

// 或者使用new Date()构造函数
let dateObject = new Date(dateString);
let timestamp2 = dateObject.getTime();
console.log(timestamp2); // 输出: 1696507680000

let dateString = "2023-10-05 14:48:00"; // 错误的格式
dateString = dateString.replace(' ', 'T'); // 转换为正确的ISO格式
let timestamp = Date.parse(dateString);
console.log(timestamp); // 正确输出

let dateString = "2023-10-05T14:48:00+08:00"; // 包含时区信息
let dateObject = new Date(dateString);
let timestamp = dateObject.getTime();
console.log(timestamp); // 输出正确的时间戳
