以指定格式输出日期字符串

Question

I have seen a lot of posts about parsing strings into dates, but not such definitive answers about the other direction, dates into strings of the desired format.

I have a Javascript Date (which I made from Date(unixtimestamp) ) and I want a string that looks like 'YYYY-MM-DD HH:MM' . Sure, I could get year, month, day, hour, and min and manually make the string with the dashes and colon, but that's multiple lines where I wonder if a single line of someone else's code will do.

Any thoughts?

Date.toISOString returns almost what you want.

var d= new Date();
var s= d.toISOString();

/* returned value: (String) 2014-07-28T18:26:46.550Z */

You can tinker with the return in the same line of code-

var d= new Date();
var s= d.toISOString().replace('T', ' ').slice(0, 16);

/* returned value: (String) 2014-07-28 18:26 */

or even:

(new Date(1406571989450)).toISOString().replace('T', ' ').slice(0, 16);

/* returned value: (String) 2014-07-28 18:26 */
