const date = new Date();
const formattedDate = date.toLocaleDateString('zh-CN', {
  year: 'numeric',
  month: '2-digit',
  day: '2-digit'
});
console.log(formattedDate); // 输出格式如 "2023/04/05"

const date = new Date();
const isoDate = date.toISOString();
console.log(isoDate); // 输出格式如 "2023-04-05T12:34:56.789Z"

function formatDate(date) {
  const year = date.getFullYear();
  const month = (date.getMonth() + 1).toString().padStart(2, '0');
  const day = date.getDate().toString().padStart(2, '0');
  return `${year}-${month}-${day}`;
}

const date = new Date();
console.log(formatDate(date)); // 输出格式如 "2023-04-05"

const date = new Date();
const options = {
  timeZone: 'Asia/Shanghai',
  year: 'numeric',
  month: '2-digit',
  day: '2-digit'
};
const formattedDate = new Intl.DateTimeFormat('zh-CN', options).format(date);
console.log(formattedDate); // 输出格式如 "2023/04/05"
