How to convert result from Date.now() to yyyy/MM/dd hh:mm:ss ffff?
提问by RollRoll
I'm looking for something like yyyy/MM/dd hh:mm:ss ffff
我正在寻找类似的东西 yyyy/MM/dd hh:mm:ss ffff
Date.now()returns the total of milliseconds (ex: 1431308705117).
Date.now()返回总毫秒数（例如：1431308705117）。
How can I do this?

You can use the Dateconstructor which takes in a number of milliseconds and converts it to a JavaScript date:
您可以使用Date构造函数，该构造函数需要几毫秒并将其转换为 JavaScript 日期：
var d = new Date(Date.now());
d.toString() // returns "Sun May 10 2015 19:50:08 GMT-0600 (MDT)"
In reality, however, doing Date(Date.now())does the same thing as Date(), so you really only have to do this:
然而，实际上，Date(Date.now())does 与做同样的事情Date()，所以你真的只需要这样做：
var d = new Date();
d.toString() // returns "Sun May 10 2015 19:50:08 GMT-0600 (MDT)"

You can use native JavaScript Date methods to achieve that or you can use a library like Moment.js.
您可以使用原生 JavaScript Date 方法来实现这一点，也可以使用像Moment.js这样的库。
It is a simple as:
这是一个简单的：
moment().format('YYYY/MM/D hh:mm:ss SSS')
If you are going use a lot of date formatting/parsing in your application then I definitely recommend using it.
如果您要在应用程序中使用大量日期格式/解析，那么我绝对推荐使用它。

You can use Date().toISOString(), i.e.:
您可以使用Date().toISOString()，即：
let d = new Date().toISOString();
alert(d);
Output:
输出：
2015-05-11T01:56:52.501Z

function formatted_date()
{
var result="";
var d = new Date();
result += d.getFullYear()+"/"+(d.getMonth()+1)+"/"+d.getDate() +
" "+ d.getHours()+":"+d.getMinutes()+":"+
d.getSeconds()+" "+d.getMilliseconds();
return result;
}
console.log(formatted_date())
Output: "2015/5/10 22:5:26 429"
输出：“2015/5/10 22:5:26 429”

function millisecondsToHuman(ms) {
const seconds = Math.floor((ms / 1000) % 60);
const minutes = Math.floor((ms / 1000 / 60) % 60);
const hours = Math.floor(ms / 1000 / 60 / 60);
const humanized = [
pad(hours.toString(), 2),
pad(minutes.toString(), 2),
pad(seconds.toString(), 2),
].join(':');
return humanized;
}
function pad(numberString, size) {
let padded = numberString;
while (padded.length < size) padded = `0${padded}`;
return padded;
}
