如何获取两个日期和时间之间的差异并显示时间

// 获取两个日期和时间的值
var date1 = new Date("2022-01-01 12:00:00");
var date2 = new Date("2022-01-02 14:30:00");

// 将日期和时间转换为时间戳
var timestamp1 = date1.getTime();
var timestamp2 = date2.getTime();

// 计算时间戳之间的差异
var diff = Math.abs(timestamp2 - timestamp1);

// 将差异的毫秒数转换为天、小时、分钟和秒的组合
var days = Math.floor(diff / (24 * 60 * 60 * 1000));
var hours = Math.floor((diff % (24 * 60 * 60 * 1000)) / (60 * 60 * 1000));
var minutes = Math.floor((diff % (60 * 60 * 1000)) / (60 * 1000));
var seconds = Math.floor((diff % (60 * 1000)) / 1000);

// 显示差异时间
console.log("时间差异：" + days + "天 " + hours + "小时 " + minutes + "分钟 " + seconds + "秒");
