js 几秒前 一小时后

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

    const intervals = [
        { seconds: 60, label: 'minute' },
        { seconds: 3600, label: 'hour' },
        { seconds: 86400, label: 'day' },
        { seconds: 604800, label: 'week' },
        { seconds: 2592000, label: 'month' },
        { seconds: 31536000, label: 'year' }
    ];

    for (const interval of intervals) {
        if (diffInSeconds < interval.seconds) {
            const value = Math.floor(diffInSeconds / (interval.seconds / 60));
            return `${value} ${interval.label}${value > 1 ? 's' : ''} ago`;
        }
    }

    return past.toLocaleString();
}

// 示例用法
const date = new Date(Date.now() - 3600 * 1000); // 一小时前的时间
console.log(timeAgo(date)); // 输出 "1 hour ago"
