隐藏日期字符串到datetime

Question

I have my date string as 17-06-2017 and I want to create it in format 2017-06-14 10:49:50 to insert in mysql database, nut I'm not able to do it like :

var now = new Date(2017-06-17).toISOString().slice(0, 19).replace('T', ' ');

Gives

"1970-01-01 00:00:01"

And

var now = new Date(17-06-2017).toISOString().slice(0, 19).replace('T', ' ');

Gives

"1969-12-31 23:59:57" ;

Need some accurate calculations here, don't understand what I'm doing wrong.

Answer 1

将日期括入这样的字符串中：

new Date("2017-06-17")

Answer 2

Well what you are doing inside the brackets here is a simple subtraction: new Date(17-06-2017) this will spit out a negative number. What you want to do is something like that:

 var now = new Date(2017,06,17).toISOString().slice(0, 19).replace('T', ' '); console.log(now) 

Answer 3

I would recommend using moment.js , it is the best library to work with dates , format , timezones.

let now = new Date();
let formattedDate = moment(now).format("YYYYMMDD HHMISS");

Answer 4

你可以用片刻做

var date=moment(yourdate).format(yourformat)
