js中的date对象格式化

const date = new Date();
console.log(date.toLocaleString()); // 输出类似于 "2023/10/5 下午3:24:00"

const options = { year: 'numeric', month: 'long', day: 'numeric' };
console.log(date.toLocaleString('zh-CN', options)); // 输出类似于 "2023年10月5日"

const formatter = new Intl.DateTimeFormat('zh-CN', {
  year: 'numeric',
  month: '2-digit',
  day: '2-digit',
  hour: '2-digit',
  minute: '2-digit',
  second: '2-digit'
});
console.log(formatter.format(new Date())); // 输出类似于 "2023/10/05 15:24:00"

const date = new Date();
const year = date.getFullYear();
const month = String(date.getMonth() + 1).padStart(2, '0');
const day = String(date.getDate()).padStart(2, '0');
const hours = String(date.getHours()).padStart(2, '0');
const minutes = String(date.getMinutes()).padStart(2, '0');
const seconds = String(date.getSeconds()).padStart(2, '0');

const formattedDate = `${year}-${month}-${day} ${hours}:${minutes}:${seconds}`;
console.log(formattedDate); // 输出类似于 "2023-10-05 15:24:00"

import { format } from 'date-fns';
import { zhCN } from 'date-fns/locale';

const date = new Date();
console.log(format(date, 'yyyy-MM-dd HH:mm:ss', { locale: zhCN })); // 输出类似于 "2023-10-05 15:24:00"
