以下是我的做法:(希望能帮助到别人) 我正在做的是验证用户在HTML时间输入中输入的时间不是过去:

let inputTime = value; // from time input in html (06:29)

const splittedInputTime = inputTime.split(':');

let currentDate = new Date();
currentDate.setHours(splittedInputTime[0]);
currentDate.setMinutes(splittedInputTime[1]);

const finalInputTime = currentDate.toTimeString().split(" ")[0];

const currentTime = new Date().toTimeString().split(" ")[0];

// Returns a boolean (true/ false)
let validTime = finalInputTime >= currentTime;

function getCurrentTime(){
    var date = new Date();
    var hh = date.getHours();
    var mm = date.getMinutes();

    hh = hh < 10 ? '0'+hh : hh; 
    mm = mm < 10 ? '0'+mm : mm;

    curr_time = hh+':'+mm;
    return curr_time;
}

这对我来说很有效，但这取决于你点击Date()时得到的结果:

Date().slice(16,-12)

简短而简单:

new Date().toLocaleTimeString(); // 11:18:48 AM
//---
new Date().toLocaleDateString(); // 11/16/2015
//---
new Date().toLocaleString(); // 11/16/2015, 11:18:48 PM

4小时后(使用milisec: sec==1000):

new Date(new Date().getTime() + 4*60*60*1000).toLocaleTimeString(); // 3:18:48 PM or 15:18:48

2天前:

new Date(new Date().getTime() - 2*24*60*60*1000).toLocaleDateString() // 11/14/2015

var today = new Date();  //gets current date and time
var hour = today.getHours();         
var minute = today.getMinutes();
var second = today.getSeconds();

看看这些Date方法…
