微博时间显示js

function timeAgo(timestamp) {
  const current = new Date();
  const past = new Date(timestamp);
  const diffInSeconds = Math.floor((current - past) / 1000);

  if (diffInSeconds < 60) {
    return '刚刚';
  } else if (diffInSeconds < 3600) {
    const minutes = Math.floor(diffInSeconds / 60);
    return `${minutes}分钟前`;
  } else if (diffInSeconds < 86400) {

    const date = past.toLocaleDateString();
    const time = past.toLocaleTimeString([], { hour: '2-digit', minute: '2-digit' });

}

// 使用示例
const postTime = new Date('2023-04-01T15:30:00').getTime();
console.log(timeAgo(postTime));

setInterval(() => {
  const updatedTime = timeAgo(postTime);
  document.getElementById('timeElement').textContent = updatedTime;
}, 60000); // 每分钟更新一次
