var d = new Date("2011-04-20T09:30:51.01");
d.getHours(); // => 9
d.getMinutes(); // =>  30

var d = new Date(); // for now
d.getHours(); // => 9

Short and simple:

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 hours later (use milisec: sec==1000):

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 days before:

2天前：

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

Get and set the current time efficiently using javascript

使用javascript有效地获取和设置当前时间

I couldn't find a solution that did exactly what I needed. I wanted clean and tiny code so I came up with this:

我找不到完全满足我需要的解决方案。我想要干净而小巧的代码，所以我想出了这个：

(Set once in your master.js and invoke when required.)

（在 master.js 中设置一次并在需要时调用。）

PURE JAVASCRIPT

纯Java脚本

function timeNow(i) {
  var d = new Date(),
    h = (d.getHours()<10?'0':'') + d.getHours(),
    m = (d.getMinutes()<10?'0':'') + d.getMinutes();
  i.value = h + ':' + m;
}

<a onclick="timeNow(test1)" href="#">SET TIME</a>
<input id="test1" type="time" value="10:40" />

UPDATE

更新

There is now sufficient browser support to simply use: toLocaleTimeString

现在有足够的浏览器支持来简单地使用： toLocaleTimeString

For html5type timethe format must be hh:mm.

对于html5类型time，格式必须是hh:mm.

function timeNow(i) {
  i.value = new Date().toLocaleTimeString([], {hour: '2-digit', minute:'2-digit'});
}

<a onclick="timeNow(test1)" href="#">SET TIME</a>
<input id="test1" type="time" value="10:40" />

Do you mean:

你的意思是：

var curr_hour = d.getHours();
var curr_min = d.getMinutes();

回答by Hamfri

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;
}

回答by Parvez Rahaman

This how you can do it.

这是你如何做到的。

const date = new Date();
const time = date.toTimeString().split(' ')[0].split(':');
console.log(time[0] + ':' + time[1])
