js代码获取当前时间

let now = new Date();
console.log(now);

let now = new Date();

let year = now.getFullYear();    // 年
let month = now.getMonth() + 1;  // 月（注意月份从0开始，所以需要+1）
let day = now.getDate();         // 日
let hours = now.getHours();       // 小时
let minutes = now.getMinutes();   // 分钟
let seconds = now.getSeconds();   // 秒

console.log(`${year}-${month}-${day} ${hours}:${minutes}:${seconds}`);

let now = new Date();
let localTime = now.toLocaleString();
console.log(localTime);

let options = { timeZone: 'Asia/Shanghai', year: 'numeric', month: '2-digit', day: '2-digit', hour: '2-digit', minute: '2-digit', second: '2-digit' };
let formatter = new Intl.DateTimeFormat('zh-CN', options);
console.log(formatter.format(new Date()));

function getCurrentTime() {
    let now = new Date();
    let year = now.getFullYear();
    let month = String(now.getMonth() + 1).padStart(2, '0');
    let day = String(now.getDate()).padStart(2, '0');
    let hours = String(now.getHours()).padStart(2, '0');
    let minutes = String(now.getMinutes()).padStart(2, '0');
    let seconds = String(now.getSeconds()).padStart(2, '0');

    return `${year}-${month}-${day} ${hours}:${minutes}:${seconds}`;
}

console.log(getCurrentTime());
