Convert javascript to date object to mysql date format (YYYY-MM-DD)

Question

I\'m trying to use javascript to convert a date object into a valid mysql date - what is the best way to do this?

Answer 1

To get date

new Date().toJSON().slice(0, 10)
//2015-07-23

for datetime

new Date().toJSON().slice(0, 19).replace('T', ' ')
//2015-07-23 11:26:00

Note, that resulting date / datetime will always be in UTC timezone

Answer 2

Probably best to use a library like Date.js (although that hasn't been maintained in years) or Moment.js.

But to do it manually, you can use Date#getFullYear(), Date#getMonth() (it starts with 0 = January, so you probably want + 1), and Date#getDate() (day of month). Just pad out the month and day to two characters, e.g.:

(function() {
    Date.prototype.toYMD = Date_toYMD;
    function Date_toYMD() {
        var year, month, day;
        year = String(this.getFullYear());
        month = String(this.getMonth() + 1);
        if (month.length == 1) {
            month = "0" + month;
        }
        day = String(this.getDate());
        if (day.length == 1) {
            day = "0" + day;
        }
        return year + "-" + month + "-" + day;
    }
})();

Usage:

var dt = new Date();
var str = dt.toYMD();

Note that the function has a name, which is useful for debugging purposes, but because of the anonymous scoping function there's no pollution of the global namespace.

That uses local time; for UTC, just use the UTC versions (getUTCFullYear, etc.).

Caveat: I just threw that out, it's completely untested.

Answer 3

From JS date to Mysql date format conversion you can simply do this:

date.toISOString().split("T")[0]

Answer 4

I needed this for a filename and with the time in the current timezone.

const timezoneOffset = (new Date()).getTimezoneOffset() * 60000;

const date = (new Date(Date.now() - timezoneOffset))
    .toISOString()
    .substring(0, 19)
    .replace('T', '')       // replace T with a space
    .replace(/ /g, "_")     // replace spaces with an underscore
    .replace(/\:/g, ".");   // replace colons with a dot

Answer 5

A bit of a typo in the first example, when a day has a length less than 1 it is adding the month instead of the day to the result.

Works great though if you change:

    if (day.length == 1) {
        day = "0" + month;
    }

to

    if (day.length == 1) {
        day = "0" + day;
    }

Thanks for posting that script.

The corrected function looks like:

Date.prototype.toYMD = Date_toYMD;
function Date_toYMD() {
    var year, month, day;
    year = String(this.getFullYear());
    month = String(this.getMonth() + 1);
    if (month.length == 1) {
        month = "0" + month;
    }
    day = String(this.getDate());
    if (day.length == 1) {
        day = "0" + day;
    }
    return year + "-" + month + "-" + day;
}

Try this

dateTimeToMYSQL(datx) {
    var d = new Date(datx),
      month = '' + (d.getMonth() + 1),
      day = d.getDate().toString(),
      year = d.getFullYear(),
      hours = d.getHours().toString(),
      minutes = d.getMinutes().toString(),
      secs = d.getSeconds().toString();
    if (month.length < 2) month = '0' + month;
    if (day.length < 2) day = '0' + day;
    if (hours.length < 2) hours = '0' + hours;
    if (minutes.length < 2) minutes = '0' + minutes;
    if (secs.length < 2) secs = '0' + secs;
    return [year, month, day].join('-') + ' ' + [hours, minutes, secs].join(':');
  }

Note that you can remove the hours, minutes and seconds and you will have the result as YYYY-MM-DD The advantage is that the datetime entered in the HTML form remains the same: no transformation into UTC

The result will be (for your example) :

dateToMYSQL(datx) {
    var d = new Date(datx),
      month = '' + (d.getMonth() + 1),
      day = d.getDate().toString(),
      year = d.getFullYear();
    if (month.length < 2) month = '0' + month;
    if (day.length < 2) day = '0' + day;
    return [year, month, day].join('-');
  }
