format javascript date as yyyy-mm-dd code example

Example 1: javascript date today dd mm yyyy

var today = new Date();
var dd = String(today.getDate()).padStart(2, '0');
var mm = String(today.getMonth() + 1).padStart(2, '0'); //January is 0!
var yyyy = today.getFullYear();

today = mm + '/' + dd + '/' + yyyy;
document.write(today);

Example 2: java script print date in YYYY-MM-DD HH:MM:SS format

let date_ob = new Date();

// adjust 0 before single digit date
let date = ("0" + date_ob.getDate()).slice(-2);

// current month
let month = ("0" + (date_ob.getMonth() + 1)).slice(-2);

// current year
let year = date_ob.getFullYear();

// current hours
let hours = date_ob.getHours();

// current minutes
let minutes = date_ob.getMinutes();

// current seconds
let seconds = date_ob.getSeconds();

// prints date & time in YYYY-MM-DD HH:MM:SS format
console.log(year + "-" + month + "-" + date + " " + hours + ":" + minutes + ":" + seconds);

Example 3: convert date format from yyyy-mm-dd to dd-mm-yyyy using value javascript

date.value.split("-").reverse().join("-");      //"2021-01-17" --> 17-01-2021

Example 4: get date format javascript

    let data= new Date(dataD)
    let month = data.getMonth() + 1
    let day = data.getDate()

    if(day<=9)
      day = '0' + day
